Method of producing butene-1

Method of producing butene-1

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 o...

Zusammenfassung: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, n-decane, toluene, diethyl ether, ethyl chloride, vinylbutyl ether, tetrahydrofuran, diphenyl ether, methylphenyl ether and their mixtures.
