Abstract

Liquid alpha-olefins predominating in normal olefins are obtained by polymerizing ethylene in the liquid phase in the presence of a hydrocarbon compound of a Group IIIA (non-transitional) metal at above 140 DEG C. and above 700 p.s.i. or P, whichever is the greater, where P, the pressure in p.s.i., is expressed by P= 33.5 T - 5,400, where T is the temperature in degrees C., recovering desired alpha-olefins and recycling undesired mono-olefins containing a vinyl group and, if desired, unreacted ethylene. Preferably, the pressure is below 4000 p.s.i. or P, whichever is lower, where P=60 T - 7700, and the temperature is 140-250 DEG C. An inert hydrocarbon, e.g. benzene, toluene or undecane, may be added in an amount of up to 14 litres per gram mol. of catalyst, preferably 0.1-5 litres and preferably the sum of the volume of diluent and half the volume of recycled vinyl olefins is at least 5 litres per gram mol. of catalyst. Preferably vinylidene olefins of the same molecular weight range as the desired product are added in amounts of 4-45 litres per gram mol. of catalysts, such olefins preferably being obtained from the product and recycled in a constant amount, any excess being discarded. Residence times of 0.25-10 hours are used. The product may be C12-C16 or C18-C24 and lower products are recycled.
