ABSTRACT:
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).sub.3 TiR' .AlR.sub.2 "OR + AlR.sub.2 "R', where R is an alkyl radical with from 2 to 4 carbon atoms, R' = R or H, R" is the same as R, or a catalyst having the formula Ti(OR).sub.4 + AlR.sub.2 "R' and modifiers such as (C.sub.5 H.sub.5).sub.2 TiCl.sub.2, oxygen, metaphenylenediamine or N-phenyl-.beta.-naphthylamine, in the medium of solvents such as n-heptane, n-decane, toluene, diethyl ether, ethyl chloride, vinylbutyl ether, tetrahydrofuran, diphenyl ether, methylphenyl ether and mixtures thereof.
The invention will find application in petrochemical processing.
