METHOD OF PRODUCING POLYETHYLENE SUCCINIMIDE Russian patent published in 2012 - IPC C08F8/32 C08F8/46 C10L1/224 C10M149/22 C08G73/10 

FIELD: chemistry.

SUBSTANCE: method of producing polyethylene succinimide involves a step for synthesis of alkenyl amber anhydride, a step for mixing the alkenyl amber anhydride with industrial oil, a step for mixing polyethylene polyamine with industrial oil and a step for synthesis of polyethylene succinimide. The novelty lies in that the step for synthesis of alkenyl amber anhydride, preliminary heating is carried out for 20-50 minutes, and holding at temperature 160-175°C is carried out for 50-60 minutes, the alkenyl amber anhydride is mixed with industrial oil in weight ratio 1:(0.70-0.79), polyethylene polyamine is mixed with industrial oil while heating to 100-106°C in weight ratio 1:(1.94-2.6), wherein preliminary mixing of the obtained solutions of alkenyl amber anhydride and polyethylene polyamine in industrial oil at the step for synthesis of polyethylene succinimide is carried out at temperature 90-110°C.

EFFECT: invention increases output of polyethylene succinimide and reduces power consumption of the process.
