    摘要: Polysulphurized olefin compositions used as additives for gear oils, cutting oils, and as sulphurizing agents in organic media are obtained by a process comprising:a stage (1) in which at least one compound chosen from among sulphur dichloride and monochloride is reacted with at least one aliphatic monpolefin with 2 to 12 carbon atoms, thus forming an adduct;a stage (2) in which sulphurized hydrogen and at least one mercaptan is reacted with ammonium or alkali metal hydroxide dissolved in at least one aliphatic monoalcohol with 1 to 4 carbon atoms, which is substantially anhydrous, so as to give an alcoholic solution;a stage (3) in which contacting takes place between the adduct obtained in stage (1) and the alcoholic solution obtained in stage (2);a stage (4), in which the resulting mixture is heated and then the aliphatic monoalcohol is eliminated by distillation, while adding water in a quantity adequate for maintaining in solution the reagents and the mineral products formed during the reaction; anda stage (5) in which elimination takes place of the aqueous phase and recovery takes place of the organic phase mainly constituted by the polysulphurized olefin composition.

    摘要: Novel (poly)sulfurized carboxylic compounds, their preparation, and their use as additives to lubricating oils are disclosed. Such novel carboxylic compounds are more particularly esters of the general formula:[R.sup.3 --OC(O)--].sub.q R.sup.2 {--C(O)O--(CH.sub.2).sub.m --CH.sub.3-z [--(CH.sub.2).sub.n --S.sub.x --R.sup.1 ].sub.z }.sub.p (1)wherein R.sup.1 is a saturated or unsaturated monovalent aliphatic radical with 1 to 30 carbon atoms; the number x is equal to or greater than 1; z equals 1 or 2; when z equals 1, n is an integer from 0 to 5 and m an integer from 0 to 0.5, with m+n an integer from 1 to 10; when z equals 2, n is an integer from 1 to 5 and m an integer from 0 to 5, with m+n an integer from 1 to 10; R.sup.2 is a hydrocarbon radical with 1 to 31 carbon atoms and a valency of p+q; R.sup.3 is a hydrogen atom or an aliphatic radical with 1 to 30 carbon atoms; p is an integer from 1 to 4; and q is an integer from 0 to 3, with p+q being an integer from 1 to 4. They are obtained by esterifying carboxylic acid R.sup.2 (--COOH).sub.p+q with a (poly)sulfurized monoalcohol:[R.sup.1 --S.sub.x --(CH.sub.2).sub.n --].sub.z CH.sub.3-z --(CH.sub.2).sub.m --OHand possibly an alcohol R.sup.3 OH. They are used as anti-wear and extreme pressure additives in lubricating oils.
