Abstract

PURPOSE: To dimerize ethylene in high activity based on catalyst, and to prepare butene-1 selectively, by using a catalyst comprising an orthotitanic acid ester through which a gas such as H2, N2, O2, etc. is previously passed and an organoaluminum compound.
CONSTITUTION: Ethylene is dimerized using a catalyst comprising an orthotitanic acid ester shown by the formula Ti(OR1)4(R1 is 1W10C hydrocarbon residue) and an organoaluminum compound shown by the formula AlR3 2(R2 is 1W10C aliphatic hydrocarbon residue), etc. In the dimerization, a gas such as hydrogen, nitrogen, oxygen, helium, neon, or argon is previously passed through the orthotitanic acid ester. A molar ratio of the organoaluminum compound to the orthotitanic acid ester is 1.5W20.
