It is an important element of the invention that the reactants be added in such quantities that the proper ratios are present for forming the double salts rather than complexes or mixtures. In connection with the object of preparingthe' double salts, rather than complexes, we have made the following observations:'
- the double salts used in the present invention are distinguished from complexes by reason of the fact that in the double salts the metal is not coordinated with amino nitrogen, whereas in the complex it is coordinated with amino nitrogen.
- one class of the double salts used'in the present invention may be structurally'po rtrayed as follows:

- the reaction to form the double salts used in the present invention may be carried out without special apparatus. It may be conducted in any convenient vessel adapted to contain the reactants. The reaction proceeds spontaneously merely by mixing or contacting the reactants in the presence of moderate heat. To facilitate contact it is desirable to dissolve the reactants in a suitable liquid solvent which is a mutual solvent for the reactants, i.e., a solvent which will dissolve each of the reactants. Preferably, the solvent should not enter into, or interfere with, the desired reaction. Generally, solvents having a minor proportion of water are suitable, as, for example, 95% aqueous ethanol. Various low molecular weight organic solvents will be suitable for the reaction, in particular the low alcohols and ketones and the lower homologs of toluene, and the like. Mixtures of such solvents may likewise be employed.
- the reaction is favored with a moderate amount of heat, although it is quite satisfactory to conduct the reaction at room temperature. Higher and lower temperatures may be employed, but at relatively high temperatures there is an undesirable tendency toward breakdown of the double salts. It is advisable to agitate and stir the reaction mixture until the reaction is substantially completed.
- reaction There is considerable variation in the length of time required for completion of the reaction. In some cases the reaction is completed almost instantaneously while in other cases several hours are required for completion. In any case, it will be clear that it is not necessary to react all of the reacting materials in order to obtain a satisfactory product. In other words, the reaction may be terminated as soon as the desired quantity of product is obtained.
- the product may be isolated from the reaction zone by any suitable method.
- the reaction mixture may be cooled so as to cause precipitation or crystallization of the product and the mixture then filtered or decanted to isolate the product. Also, it will be satisfactory to evaporate the solvent and thereby leave the desired product as a residue.
- the double salts are used as an active ingredient in compositions for combating fungal attack.
- Such compositions can take the form of emulsions, solutions, powders, etc.
- the double salts are not applied in full strength, but instead are combined with an inert carrier so that a fungistatic but non-phytotoxic concentration of the double salts can be applied. It has been found that there is a considerable margin of safety between active and phytotoxic concentrations.
- an effective fungistatic or fungitoxic action is obtained in concentrations ranging from to 100 parts per million, whereas no phytotoxicity is exhibited in concentrations of 1,000 parts per million or more, and in the hardier plants concentrations as high as 5,000 and 6,000 parts per million produce no phytotoxicity.
- concentrations are in terms of solutions or suspensions which are sprayed on plants and that such concentrations are subject to upward adjustment when used in connection with dry, powdered compositions which are applied by dusting on plants.

6 Claims. (Cl. 167 -22)' This invention relates to fungicidal compositions containing as the essential active ingredient the double salts of heavy metal salts and certain amine hydrohalides.
The novel compounds of the present invention comprise a carrier and an effective concentration of a double salt of a heavy metal salt and an amine hydrohalide, said amine-having the formula RRR' N, wherein R is an aliphatic hydrocarbon radical having from 8 to 20 carbon atoms and R is either hydrogen or an aliphatic hydrocarbonradical having from 1 to 20 carbon atoms.
The double salts which form a part of the compounds of this invention are produced, generally, by forming a solution containing an amine and a hydrogen halide gas such as hydrogen chloride and adding a solution containing a heavy metal salt. It is an important element of the invention that the reactants be added in such quantities that the proper ratios are present for forming the double salts rather than complexes or mixtures. In connection with the object of preparingthe' double salts, rather than complexes, we have made the following observations:'
(1) When long-chainN-substituted amines are used with heavy metal salts, the resulting double salts or complexes in most cases involve 2 moles of the amine for each mole of heavy metal compound.
p (2) When primary or secondary amines are mixed with heavy metal salts, complexes between the two substances are formed unless sufficient hydrogen halide is present to neutralize or block all the nitrogen atoms and thus prevent the formation of complexes or coordination compounds. c
(3) Therefore, in order to prepare double salts of primary or secondary amines, it is necessary to add enough moles of hydrogen halide to neutralize or block all of the amino groups. lnother Words, for each mole of heavy metal salts, it is necessary to add 2 moles of hydrogen halide along with the 2 moles of amine. The double salt used in the present invention therefore involves a 222:1 molar ratio of aminezhydrogen halidezheavy metal salt.
Although in the foregoing description the carrying out of the reaction is described in terms of adding three ingredients, namely, the amine, the hydrogen halide, and the heavy metal salt, it will be understood that the invention also contemplates the use of equivalent procedures and materials such as, for example, the use of an amine hydrohalide instead of the amine and the hydrogen halide separately.
Structurally, the double salts used in the present invention are distinguished from complexes by reason of the fact that in the double salts the metal is not coordinated with amino nitrogen, whereas in the complex it is coordinated with amino nitrogen. Thus, as an illustration, one class of the double salts used'in the present invention may be structurally'po rtrayed as follows:
The structural formula for the above may be given as follows:
(RRRNH) +(MX wherein R is an aliphatic hydrocarbon radical having from 8 to 20 carbon atoms and R is either hydrogen or an aliphatic hydrocarbon radical having from 1 to 20 carbon atoms, X is halide, and M is a heavy metal.
As a further means of distinguishing the double salts of this invention, the color may be employed as an identifying factor in the case of some of the heavy metal compounds. Thus, for example, when copper is used as the heavy metal, the double salts of the present invention under normal conditions have a characteristic yellow color, as distinguished from the dark blue or purple color of secondary amine copper chloride complexes or the light blue color of primary amine copper chloride complexes.
Any suitable heavy metal may be used as a component of the double salts contemplated by the present invention. Such metals are to be found in groups I-B, IIB,VIB, VII-B, and VIII of the periodic chart of the elements. As specific examples, we may use the salts of heavy metals such as copper, chromium, tin, Zinc, cadmium, mercury, manganese, iron, cobalt, and nickel. The use of copper, cadmium, zinc, manganese, and iron salts is preferred. Although we prefer to use halides as the anionic portion of the heavy metal salts, it will be understood that other suitable anions such as acetate, sulphate, nitrate, and oxalate may also be used.
Any primary, secondary, or tertiary saturated or unsaturated amine, containing at least'one long chain aliphatic group having from 8 to 20 carbon atoms, will serve as a starting material in forming the double salts used in the present invention. The amine starting material may be represented generally by the formula RRR'N wherein R is an aliphatic hydrocarbon radical having from 8 to 20 carbon atoms and R' is either hydrogen or an aliphatic hydrocarbon radical of from 1 to 20 carbon atoms. As representative members of R in the above formula, the following may be mentioned: octyl, decyl, dodecyl, dodecenyl, tetradecyl, tetradecenyl, hexadecyl, hexadecenyl, octadecyl, octadecenyl, and octadecadienyl. The R may also constitute mixtures of long chain aliphatic radicals such as those found in natural fatty acid mixtures obtained from coconut oil, cottonseed oil, soybean oil, or lard oils. Thus, for example, there may be used talloW-amines (derived from tallow and in which tallow comprises a mixture of the following radicals: dodecyl, tetradecyl, tetradecenyl, hexadecyl, hexadecenyl, octadecyl, octadecenyl, octadecadienyl, and eicosyl); cocoamines (derived from coconut oil and in which coco comprises a mixture of hexyl, octyl, decyl, dodecyl, tetradecyl, hexadecyl, octadecyl, octadecenyl, and octadecadienyl radicals); and soya-amines (derived from soybean oil and in which soya comprises a mixture of hexadecyl, octadecyl, eicosyl, octadecenyl, octadecadienyl, and octadecatrienyl radicals). Hereinafter, the terms tallow, coco, and soya are meant to refer to the respective mixtures of radicals set forth above.
The R in the above amine formula may be either hydrogen or an aliphatic hydrocarbon radical of from 1 to 20 carbon atoms. The aliphatic hydrocarbon radical may thus be any of the radicals falling under the definition of R given above and in addition may comprise members such as methyl, ethyl, propyl, butyl, hexyl, and mixtures thereof.
The reaction to form the double salts used in the present invention may be carried out without special apparatus. It may be conducted in any convenient vessel adapted to contain the reactants. The reaction proceeds spontaneously merely by mixing or contacting the reactants in the presence of moderate heat. To facilitate contact it is desirable to dissolve the reactants in a suitable liquid solvent which is a mutual solvent for the reactants, i.e., a solvent which will dissolve each of the reactants. Preferably, the solvent should not enter into, or interfere with, the desired reaction. Generally, solvents having a minor proportion of water are suitable, as, for example, 95% aqueous ethanol. Various low molecular weight organic solvents will be suitable for the reaction, in particular the low alcohols and ketones and the lower homologs of toluene, and the like. Mixtures of such solvents may likewise be employed.
According to the preferred practice, the reaction is favored with a moderate amount of heat, although it is quite satisfactory to conduct the reaction at room temperature. Higher and lower temperatures may be employed, but at relatively high temperatures there is an undesirable tendency toward breakdown of the double salts. It is advisable to agitate and stir the reaction mixture until the reaction is substantially completed.
There is considerable variation in the length of time required for completion of the reaction. In some cases the reaction is completed almost instantaneously while in other cases several hours are required for completion. In any case, it will be clear that it is not necessary to react all of the reacting materials in order to obtain a satisfactory product. In other words, the reaction may be terminated as soon as the desired quantity of product is obtained.
Following the desired reaction the product may be isolated from the reaction zone by any suitable method. For example, the reaction mixture may be cooled so as to cause precipitation or crystallization of the product and the mixture then filtered or decanted to isolate the product. Also, it will be satisfactory to evaporate the solvent and thereby leave the desired product as a residue.
In the present invention, the double salts are used as an active ingredient in compositions for combating fungal attack. Such compositions can take the form of emulsions, solutions, powders, etc. When used on growing plants, the double salts are not applied in full strength, but instead are combined with an inert carrier so that a fungistatic but non-phytotoxic concentration of the double salts can be applied. It has been found that there is a considerable margin of safety between active and phytotoxic concentrations. For example, with most of the compounds falling within the scope of this invention, an effective fungistatic or fungitoxic action is obtained in concentrations ranging from to 100 parts per million, whereas no phytotoxicity is exhibited in concentrations of 1,000 parts per million or more, and in the hardier plants concentrations as high as 5,000 and 6,000 parts per million produce no phytotoxicity. This permits the fungicidal composition of this invention to be sprayed or dusted on plants without danger of phytotoxicity due to over concentrations. It will be understood that the above concentrations are in terms of solutions or suspensions which are sprayed on plants and that such concentrations are subject to upward adjustment when used in connection with dry, powdered compositions which are applied by dusting on plants.
