Abstract

1-Butene is obtained using a catalyst system comprising (a) a reducing Al compound HX Al N (R1) (R2) where R1, R2 independently are 1-10C hydrocarbon and X = H or halogen, e.g. Cl, Br or I and (b) Ti(OR)4 where R4 = 1 - 10C hydrocarbon. Reaction is preferably in a solvent chosen from (cyclo)aliphatic and aromatic hydrocarbons, under 1 - 100 atm. pressure. Example: 5 atm. C2H4 introduced to autoclave at 65 degrees C containing 51.0 m moles H2AlN(CH3)2 in 100 cm3 toluene. 17.0 m moles Ti(O-isoC3H7)4 in 15 cm3 toluene were added. Pressure raised to 20 atm. C2H4; agitation continued for 3 hrs. 94% C2H4 was converted to 1-butene; 0.6 g. high density polyethylene was obtained also.
