This invention provides an improved process for the preparation of an aluminum alkyl chain growth product by the chain growth reaction of alpha-olefins on aluminum alkyl, the improvement comprising catalyzing the chain growth reaction that is a partially oxidized aluminum alkyl.

Alpha-olefin catalyst and process

A process for separating a mixture of aluminum alkyl and alpha-olefin, said process comprising contacting a silica modified inorganic membrane filter with said mixture and recovering, as the permeate, an alpha-olefin fraction which contains a lower concentration of aluminum alkyl than in said mixture, as the retentate, an aluminum alkyl fraction which contains a higher concentration of aluminum alkyl than in said mixture.

Separation of aluminum alkyls from olefins using modified inorganic

A process for separating a mixture of aluminum alkyl and alpha-olefin comprises contacting, under an elevated pressure of at least about 300 psig, an organic solvent stable, polyphenylene oxide-derived membrane with said mixture and recovering as the permeate an alpha-olefin fraction which contains a lower concentration of aluminum alkyl than in the starting mixture.

Separation of aluminum alkyls from olefins using polyphenylene oxide

An improved process for making olefins from a lower olefin such as ethylene and an alkyl aluminum by chain growth employes a butene displacement reaction using mixing device such as a static mixer which permits efficient operation of the displacement reaction at moderate pressures where the reactants form a two-phase vapor-liquid system or a vapor system.
