METHOD OF SYNTHESIS OF APPLIED CATALYST USED FOR GAS-PHASE POLYMERIZATION OF ETHYLENE AND COPOLYMERIZATION OF ETHYLENE WITH α-OLEFINS Russian patent published in 1994 - IPC

Abstract RU 2007424 C1

FIELD: organic chemistry. SUBSTANCE: solution of organomagnesium compound of the general formula , where R′=C2H5, i=C4H9, R″=н=C4H9, i=C5H11; a = 0,01-0,1; b = 0,5-2,0, in chloro- benzene is interacted with CCl4 at mole ratio CCl4/Mg = 3-5 at 50-70 C following by treatment of solid product formed with solution of ethylaluminium chloride of the general formula (ElAlCl2,El2AlCl,El3Al2Cl3) and then - with solution of TiCl4 or VOCl3 at mole ratio Al/Mg = 0,5-2,0 and Ti(V)/Mo= 0,01-0,1 at 20-60 C. Method is used for synthesis of catalyst. EFFECT: improved method of synthesis. 1 tbl
