Process for the preparation of sulphur-containing additives for use in lubricant compositions and a lubricant composition in which there is incorporated a sulphur-containing additive. |
摘要 |
<p>A process for the preparation of sulphur-containing additives for use in lubricant compositions, in which process an organic carboxylic acid, an ester and/or amide derived therefrom is/are sulphurized in a manner known in itself.
<??>The carboxylic acid or the acid from which the ester and/or amide are/is derived is obtained by telomerization under inert conditions of an ethylenically unsaturated compound in the presence of an at least trivalent manganese compound with a carbonyl compound whose alpha-carbon atom carries at least one hydrogen atom, with the proviso that
a. the carbonyl compound contains at least 60% by weight of a carboxylic anhydride;
b. a trivalent manganese compound is present in an amount of 10<-><3> to 10<-><1><0> moles;
c. the molar ratio of the converted amount of ethylenically unsaturated compounds to said trivalent manganese compound is at least 4.
<??>There is also provided a lubricant composition in which there is incorporated a sulphur-containing additive obtained by the above-process.</p> |
