摘要： Butene-1 is prepared by 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 napthylamine, 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.
