    • 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.
    • 公开了新型(多)硫化羧酸化合物,它们的制备及其作为润滑油添加剂的用途。 这样的新型羧酸化合物更特别是以下通式的酯:(R3-OC(O) - )qR2(-C(O)O-(CH2)m-CH3-z( - (CH2)n-Sx-R1) z)p(1)其中R1是具有1至30个碳原子的饱和或不饱和的一价脂族基; 数x等于或大于1; z等于1或2; 当z为1时,n为0〜5的整数,m为0〜0.5的整数,m + n为1〜10的整数。 当z为2时,n为1〜5的整数,m为0〜5的整数,m + n为1〜10的整数。 R2是具有1至31个碳原子并且p + q的化合价的烃基; R3是氢原子或具有1至30个碳原子的脂族基团; p是1至4的整数; 并且q为0〜3的整数,p + q为1〜4的整数。它们是通过用(多)硫化一元醇将羧酸R2(-COOH)p + q酯化得到的:(R1-Sx- (CH 2)n - )z CH 3 -Z-(CH 2)m -OH以及可能的醇R 3 OH。 它们用作润滑油中的抗磨和极压添加剂。
