SU418462A1 - METHOD FOR PREPARING C ^ –C ^ 1 OLEFIN MIXTURE The invention relates to a process for producing a mixture of C4 – Ce olefins with a predominance of alpha isomers, which are widely used as monomers and intermediates in the synthesis of plastics and rubber. —Cb by sodimerization of ethylene with propylene at a temperature of 100–160 ° C and a pressure of 40 atm in the presence of trialkylaluminium, for example, triethylaluminium or diethylaluminium chloride, and a transition metal compound, for example, nickel chloride or its oxide. The known method relates to a low yield of alpha-olefins and an insufficiently high degree of conversion of propylene. In order to increase the yield of alpha-olefins, it is proposed to use nickel palmitate as a compound of the transition metal. Example. 250 ml (180 g) of a catalyst consisting of a 3% solution of triethylalu-5 mini in n-decape and nickel palmitate (A1: N1 = 500: 1) is placed in a 2 l autoclave pre-freed from moisture and oxygen, equipped with a magnetic stirrer (1400 rpm). Then 235 g10 propylene (99.5% purity) and 157 g ethylene (99.8% purity) are fed. The molar ratio is 1: 1. Heated to the desired temperature and stirred for 20 hours. Together with alpha-olefins C4 — Sb, a small amount of al-15 fa-olefins Cs — Ce is formed. - Google Patents
