A vulcanization accelerator combination based on di-(C.sub.6 -C.sub.12 alkyl)dithiophosphates for vulcanizing non-polar rubbers, comprising the following components: (a) a di-(C.sub.6 -C.sub.12 alkyl)dithiophosphate; (b) one or more compounds selected from the group consisting of sulphenamides, thiazoles and carbamates; (c) sulfur and/or a sulfur donor; and (d) at least one additional accelerator compound having a specific chemical structure that is different from the chemical structure of component (a) and any of the compounds used as component (b) in said accelerator combination.

Accelerator combinations

A process for the phosphorylation of epoxides, in particular of epoxidised fatty acid esters, and the use of the phosphorylation products for the production of lubricants.

Phosphorylation of epoxides

Alkyl glycidol ether/dithiophosphoric acid addition products corresponding to the following general formula:

Metal-free dithiophosphoric acid derivatives

A method for improving the corrosion inhibition of lubricating oils especially those of vegetable origin which comprises adding an efficient amount of the reaction product of an epoxidized fatty acid ester, especially an epoxidized methyl ester of an unsaturated fatty acid and a sulphonic acid and a process for producing these reaction products.
