METHOD FOR PRODUCING OF POLYOLEFIN SUCCINIMIDE Russian patent published in 2017 - IPC C08F8/32 C08F8/46 C10L1/224 C10M149/22 C08G73/10 

FIELD: oil-and-gas industry.

SUBSTANCE: invention relates to basic organic and petrochemical synthesis, in particular to the method for producing of polyolefin succinimide used for prevention of formation of carbon deposits on parts of internal combustion engines. The method includes the step of alkenyl succinic anhydride synthesis in a reactor with a stirrer with preheating of reaction mixture components, polyolefin succinimide synthesis stage. At the stage of synthesis of polyolefin succinimide oligomers of unsaturated hydrocarbons C₂-C₄ with the molecular weight 260-1500 and polyethylene polyamine solution with hetero organic compound with the gross formula C_xH_yO_nN_m.

EFFECT: method simplifies the process, reduces power consumption and duration of the process, and minimizes the formation of homopolymers of maleic anhydride and polymers insoluble in oil and increases the yield of finished product.
