METHOD FOR PRODUCTION OF ALKENYLSUCCINIC ACID IMIDES Russian patent published in 2007 - IPC C08F8/32 C08F8/46 C08G73/10 C10M149/22 C10L1/22 

FIELD: organic chemistry, polymers.

SUBSTANCE: claimed method includes alkylation of maleic anhydride with C₁₀-C₃₀-poly-alpha-olefin having molecular mass of 700-1100 in presence of initiator, previously at 60-100°C for 1.0-1.5 h and further at 160-170°C for 3-4 h and holding at 175-180°C for 0.5 h in poly-alpha-olefin/maleic anhydride ratio of 1:1-1.1 followed by condensation of obtained alkylated succinic anhydride with mixture, containing polyethylene polyamines at 50-110°C for 1.-1.5 h and followed heating at 135-145 °C for 3.5-4 h in alkylated succinic anhydride/mixture (polyethylene polyamines) molar ratio of 1:1.1 in oil or aromatic hydrocarbons (such as industrial oils, ortho- or para-xylene, or solvents, such as xylene mixture, respectively). As mixture of polyethylene polyamines mixture of triehylenetetramine and tetraethylenepentamine in amount of 40-70 mass % and 20-50 mass %, respectively is used, and as initiator tert-butyl peroxide or methylethylketone peroxide in amount of 1-2.0 % based on the weight of starting poly-alpha-olefin and maleic anhydride is used.

EFFECT: simplified process; product of increased quality.
