Abstract
The invention concerns an improved process for the conversion of ethylene into but-1-ene, wherein the ethylene is brought into contact with a catalyst obtained by the interaction of an alkyl titanate, possibly mixed with an ether, with a compound of aluminium of the formula AlR.sub.3 or AlR.sub.2 H, and in the presence of an additive formed by at least one polyethylene glycol and/or one of its derivatives such as a monoether or a monoester of polyethylene glycol.
Claims21
A process for the conversion of ethylene to but- 1-ene, comprising contacting, in a reactor, under effective conditions, ethylene with a solution of a catalyst resulting from the interaction of at least one alkyl titanate with at least one aluminum compound of the formula AlR.sub.3 or AIR.sub.2 H, each of the residues R being a hydrocarbyl radical, the process being conducted in the presence of at least one additive which is polyethylene glycol or a monoether or monoester thereof.
