摘要:
The present invention relates to a method of producing butene-1. According to the invention, the method of producing butene-1 resides in dimerizing ethylene in the presence of a complex organometallic catalyst of the formula (RO)3TiR''.AlR2''''OR + AlR2''''R'', where R is an alkyl radical with the number of carbon atoms from 2 to 4, R'' R or H, R'''' is the same as R, or of a catalyst of the formula Ti(OR)4 + AlR2''''R'' and modifiers such as (C5H5)2TiCl2, oxygen, metaphenylenediamine or N-phenyl- Beta naphthylamine, in the medium of solvents such as n-heptane, ndecane, toluene, diethyl ether, ethyl chloride, vinylbutyl ether, tetrahydrofuran, diphenyl ether, methylphenyl ether and their mixtures. The invention will find application in petrochemical processing.
摘要:
A catalyst for polymerization and copolymerization of olefins is a binary system consisting of a complex compound formed by a halide of a transition metal belonging to Groups IVA-VA of the periodic system with polyglycolic ethers of mono- or polyfunctional alcohols, or polyglycolic esters of carboxylic acids or their anhydrosorbitols, in combination with aluminumorganic compounds. The said complex compounds are prepared by the interaction between said ethers (esters) and halides of transition metals in organic solvents in an inert medium.
