ACTIVATION OF THE Ti(OC4H9)4-Al(C2H5)C CATALYTIC SYSTEM IN THE SELECTIVE DIMERIZATION OF ETHYLENE TO 1-BUTENE BY THE GRIGNARD REAGENT

Article abstract of DOI:10.1007/BF00863808

The effect of an organomagnesium compound on the dimerization of ethylene to 1-butene was studied. The organomagnesium compound increases the catalytic activity of the Ti(OC4H9)4-Al(C2H5)3 system by 5-10 times. A high degree of selectivity (up to 99percent) with respect to 1-butene was obtained. This makes it possible to eliminate a series of technological difficulties involved in the industrial production of 1-butene. The kinetics of the reduction of Ti(OC4H9)4 by butylmagnesium chloride were studied by ESR and polarography. Keywords: dimerization, kinetics, ethylene, organomagnesium compound, 1-butene, selectivity, catalytic activity, polarography, reduction.
