' SULFONIC ACE) CONDENSATION PRODUCTS AND IVETHODS F PRODUCING THE SAME No Drawing. Application August 3, 1954 Serial No. 447,665
Claims priority, application Germany August 4, 1953 15 Claims. (Cl. 260-2934) This invention relates to sulfonic acid condensation products and methods of producing the same, and more particularly to such products derived from sulfhydryl compounds and sultones.
We have found that valuable new organic compounds are obtained by subjecting organic sulfhydryl compounds which contain one or more aliphatic, cycloaliphatic or aromatic hydrocarbon radicals, bonded directly or through an oxygen, sulfur or nitrogen atom to a COSH or -CSSH group, to a condensation reaction with a sultone. The sulfhydryl compounds referred to are reacted with the sultones in the form of their mercaptides or in the presence of acid-binding agents. The term sultones as used herein refers to cyclic sulfonic acid anhydrides of oxyalkylsulfonic acids. The products produced by the condensation reaction in accordance with this invention are substituted alkylsulfonic acid salts.
sulfhydryl compounds which may be reacted in the form of their salts with sultones in accordance with'our invention include, for example, aliphatic or aromatic thiolacids and dithioacids having the general structural formulas wherein R is an aliphatic or an aromatic hydrocarbon radical.
However, sultones can also be reacted with derivatives of thiocarbonic acids in accordance with our invention to yield the desired sulfonic acid compounds. The derivatives of thiocarbonic acid concerned contain a free saltforming COSH group bonded to an aliphatic or aromatic hydrocarbon radical through an oxygen, sulfur or nitrogen atom, and have the general structural for mulas /SH /SH /SH C O O=O Cio O R S R NH R wherein R represents the aliphatic or aromatic hydrocarbon radical. Examples of such derivatives of thiocarbonic acids are thiocarbonic acid ethyl ester, thiocarbonic acid-monoethylamide, and the like.
Sultones may also be reacted in accordance with our invention with the corresponding derivatives of sulfthiocarbonic acid, i. e. those compounds which contain a free salt-forming CSSH group bonded through an oxygen, sulfur or nitrogen atom to an aliphatic or aroent w matic hydrocarbon radical. Such derivatives of sulfthiocarbonic acid have the general structural formulas wherein R represents an aliphatic or aromatic hydrocarbon radical.
Members of this group of compounds are primarily the ester salts of sulfthiocarbonic acid, known as xanthogenates, which can be readily prepared from organic oxycompounds and carbon disulfide. Examples of xanthogenates which may be employed in the reaction with sultones in accordance with our invention are methyl-, ethyl-, propyl-, allyl-, butyl-, amyland cetyl-xanthogenates, as well as phenyl-, cresyl-, naphthy1-, 4-chlorophenyl-, 2,4- dichlorophenyl-xanthogenates, and the like.
Other members of this group of compounds are the ester salts of trithiocarbonic acid, known as thioxantho-' genates, which can be readily prepared from mercaptides and carbon disulfide. Examples of thioxanthogenates which may be employed in the reaction with sultones in accordance with our invention are the salts of ethyl-trithiocarbonic acid, isobutyl-trithiocarbonic acid, phenyltrithiocarbonic acid, and the like.
Finally, those compounds which contain a nitrogen atom, such as the salts of dithiocarbamino acid or dithiocarbazic acid, obtained by reacting ammonia, organic amines or hydrazines with carbon disulfide, are also suitable for the reaction in accordance with our invention with sultones. Examples of such salts of dithiocarbamino acid or dithiocarbazic acid are dithiocarbamic acid, N,N- dimethyl-dithiocarbamic acid, N,N-diethyl-dithiocarbamic acid, N,N-pentamethylene-dithiocarbamic acid, N-ethyl- N-phenyl-dithiocarbamic acid, N-phenyl-dithiocarbamic acid, N-naphthyl-l-dithiocarbamic acid, N-4-chlorophenyldithiocarbamic acid, N-phenyl-dithiocarbazic acid, N,N- dimethyl-dithiocarbazic acid, ethylene-1,2-bis-dithiocarbamic acid, and the like.
Sultones which may be condensed with the above sulfhydryl compounds in accordance with our invention are 1,3-propane sultone or 1,4-butane sultone, or technical mixtures thereof. However, sultone derivatives comprising substituents attached to any one of the carbon atoms of the hydrocarbon chain may also be used. Such substituted sultones include, for example, 1,1-dimethyl-L3- propane sultone (isopentane sultone). Finally, sultones in which hydrogen atoms of a cycloaliphatic or aromatic ring form a part of the sultone ring may be employed in the condensation reaction in accordance with our invention to form sulfonic acid derivatives. Substituted sultones of this type include, for example, tolyl, 1,8- naphtho-sultone, and many others.
The condensation reaction between sultones and sulfhydryl compounds in accordance with our invention, in which the sulfhydryl group is a component of a strongly acid group, takes place surprisingly rapidly and goes virtually to its theoretical completion. In most instances it is not necessary to apply any special means to start the condensation reaction, and the reaction is so vigorous that external cooling means should be provided.
While it is possible to carry out the reaction with the reactants in contact with each other in their undiluted form, the employment of suitable solvents or diluents is recommended. Substances suitable for this purpose are, for example, organic solvents such as alcohols, ketones, cyclic ethers such as dioxane, or ether-alcohols such as tetrahydrofurfural, and many others.
The sulfonic acid salts formed by the condensation reaction in accordance, with our invention precipitate from the reaction mass in a very pure crystalline form when organic solvents or diluents are present. In contrast to the very unstable thioand dithio-compounds from which they are formed, the sulfonic acid salts produced by the reaction in accordance with this invention are surprisingly stable.
The sulfhydryl-sulfonic acid condensation products disclosed herein find their practical application in the field of accelerators for vulcanization processes and furthermore as pharmaceutical agents or intermediates for them.
The following examples will enable persons skilled in the artto understand our invention more completely. It is understood, however, that our invention is not limited to these examples or to the specific terms and conditions stated in said examples.

The crystalline reaction product was colorless, odorless, stable and formed a clear solution in water. The yield was very high.
Example V 11.0 parts by weight of ammonium salt of dithiocarbamic acid A mol), prepared in accordance with Freund and Barerach, Annalen 285, p. 201, were suspended in 200 parts by volume of isopropanol, and subsequently 12.2 parts by weight of 1,3-propane sultone A mol) were added to this suspension at 35 C.
