METHOD OF PRODUCING SULPHUR-CONTAINING ADDITIVE Russian patent published in 2011 - IPC C10M135/04

Abstract RU 2423413 C2

FIELD: chemistry.

SUBSTANCE: present invention relates to synthesis of sulphur-containing additives. Described is a method of producing a sulphur-containing additive by reacting α-olefins with elementary sulphur at high temperature in the presence of a nitrogen-containing catalyst, characterised by that the nitrogen-containing catalyst used is 2-[(hydroxymethyl)amino]-1-ethanol in amount of 0.05-0.10 wt % with respect to the C₁₀-C₁₂ α-olefin fraction.

EFFECT: high output of the sulphur-containing additive and simplification of the process.
