Preparation of linear olefin products

摘要

In a process for preparing linear olefins which comprises polymerizing an ethylene containing gas in the presence of a catalyst comprising the reaction product of a transition metal halide and an aluminum alkyl compound in the presence of a diluent and maintaining the mole ratio of ethylene to olefin reaction product at a relatively high level so as to produce a product comprising at least 90 mole % linear olefins, the process is improved and the product purity is maintained by killing the activity of the catalyst prior to the occurrence of deleterious side reactions which tend to reduce the product purity.
