METHOD FOR PRODUCTION OF LINEAR α-OLEFINS C-C Russian patent published in 1995 - IPC

Abstract RU 2032647 C1

FIELD: organic chemistry. SUBSTANCE: ethylene is oligomerized at 50-120 C and pressure 10-50 atm. The process is carried out in medium of aromatic hydrocarbon or halide hydrocarbon solvent in the presence of catalytic system. Said system contains compounds of zirconium, ethyl aliminiumsesquichloride and ether having formula R2O where R is alkyl C2-C5 phenyl. Molar ratio of mentioned above components is 1:(1-3):(12-30). Zr(R′COO)Cl4-n is used as said zirconium compound, R′-alkylC3-C16 n=2 or 3. Output of the process is 18.88 kg per 1 g Zr per 1 h. EFFECT: improves efficiency of the method. 1 tbl
