Definitions

  • the invention relates to novel complex compounds of boric acid, salicylic acid or its derivatives and silver, method of their preparation, and a preparation containing these compounds for use against moulds, fungi and ligniperdous insects.
  • Silver and its compounds are very efficient preparations against moulds and fungi or general disinfectants.
  • the mechanism of action of silver, which is applied mainly in colloidal form, is not fully understood.

C. Bailar, Jr. et al., Eds., Pergamon Press, Oxford, 1973).
  • Commercially available are also organometallic compounds of silver which exhibit these properties, too.
  • metal-free derivatives of both series exhibit biological effects, e.g., 4-aminosalicylic acid has strong antibacterial effects (for overview of these compounds see e.g., The Merck Index, An Encyclopedia of Chemicals, Drugs, and Biologicals, 12 th edition, Merck Research Laboratories, 1996), which can probably be ascribed to the formation of the zwitterionic form ( + H 3 N-C 6 H 3 (OH)-COO ⁇ ).
  • the drawback of the compounds A and B consists in that they actually are pigments, which poorly penetrate into the substrate treated and can be easily removed from its surface.
  • boric acid or its salt are efficient preparations against ligniperdous (wood-destroying) insects; these compounds act as protecting agents against moulds, fungi and ligniperdous insects also in nature (e.g., in roots of plants).
  • the disadvantage of both these boron compounds is that they are soluble in water, so that the protection of a material that is exposed to the action of water is not long- lasting.
  • esters of boric acid e.g., the ester of boric acid and glycerol, which have similar effects and are less soluble in water and readily soluble in ethanol (Sciarra, Elliot, J. Am. Pharm. Assoc. (Sci. Ed.) 49, 116 (1960)).
  • their biological efficiency, particularly against moulds is low, and the mould will be destroyed neither by boric acid nor by borax once the substrate has already been attacked by the mould.
  • Boric acid (H 3 BO 3 ) is known to be a weak monoprotic acid of a limited solubility in water, which does not act as a proton donor but acts as a Lewis acid.
  • Salicylic acid or its derivatives form tetrahedral complexes with boric acid at the ratio of 1 : 1 or 2 : 1 (see Reaction in the boric acid-salicylic acid system.
  • Distinct disinfecting effects are also exhibited by cationic, i.e. basic dyestuffs, in which the chromophore carries a positive charge counterbalanced by a simple anion.
  • cationic i.e. basic dyestuffs
  • the best known representatives e.g., are Crystal violet and Gentian violet (for a toxicological study, see H. C. Hodge et a/., Toxicol. Appl. Pharmacol. 22, 1 (1972)).
  • these compounds bind to phosphate group, thereby preventing the formation of adenosine triphosphate and, hence, the nutrition of the cell.
  • All tetraalkyl- or tetraaryl-ammonium compounds i.e.
  • the drawback of the solutions known so far consists either in the insolubility of the active components and the prevention of the saturation of the material treated, or - on the contrary, - in their high solubility and readily washing out from the material treated.
  • individual components possess specific activities, i.e. they are only efficient against some kinds of pest microorganisms, as described herein above.
  • Object of the present invention are new complex compounds of boric acid, salicylic acid or its derivatives and silver of general formula I,
  • Object of the invention is further a method of preparation of the complex compound of general formula I, consisting in preparation of a solution of one molar unit of boric acid and two molar units of salicylic acid or its derivative in a polar solvent under stirring, whereas the concentration of salicylic acid or its derivative in the solution is in the range of 0.2-50 % wt.
  • the solution is prepared at the temperature ranging from 0 0 C to the boiling point of the polar solvent used, then one molar unit of silver nitrate is added with stirring into the solution of boric acid and salicylic acid or its derivative, and the resulting solution is cooled to the temperature of 0-25 0 C, and the formed precipitate of the complex compound is then collected by filtration and dried at the temperature of 25-80 0 C.
  • the solution of boric acid and salicylic acid or its derivative in the polar solvent is prepared at room temperature.

  • Object of the invention is further a preparation for killing moulds, fungi and ligniperdous insects, which contains as an active agent at least one complex compound of general formula I, solvents and optionally suitable auxiliary substances.
  • the above described compounds of general formula I are insoluble in water. On the other hand, they are soluble in mixtures of water and alcohol, the solubility in alcohol being the higher, the longer the aliphatic chain R is. Hence, they are applied in the form of these solutions, wherein the active agent (complex compound I) penetrates by diffusion into the material treated. After a certain period of time, the complex compound I is gradually decomposed and silver is produced by the reduction (ethanol acts on Ag + as a reducing agent); the silver in atomic form is then evenly distributed throughout the material, which brings very high biological efficiency with it. Of course, silver is also insoluble in water; therefore, it cannot be washed out from the treated material by water or by organic solvents. Boric acid and salicylic acid or its derivative has fungicidal effects in the material treated, too. Thus, the preparation acts not only as a preventive protection of the material, but also as a highly efficient killer of harmful micro-organisms.

  • the preparation according to this invention can be stabilised by an addition of hydrogen peroxide.
  • Hydrogen peroxide prevents the reduction and the formation of silver in the solution.
  • This preferred preparation is prepared by first preparing the required hydrogen peroxide solution in water and then adding alcohol and finally adding the complex compound of general formula I.
  • the preparation of this invention contains 0.001- 10 % wt. of the complex compound of general formula I, 25 - 98 % wt. of C 2 to C 3 alcohol, and 2 - 75 % wt. of water, and optionally further auxiliary substances, such as dyestuffs and stabilisers.
