摘要： When ethylene is telomerized to produce alpha-olefins in the presence of an organo-aluminum catalyst, the aluminum catalyst is present in the normally liquid alpha-olefin product and must be removed prior to distillation of that product. This removal is accomplished in two zones. Water is added to the alpha-olefin product containing the organo-aluminum catalyst in a first zone to produce an aqueous phase containing a suspension of aluminum hydroxide and an organic phase containing the alpha-olefins. After removal of the organic phase, a sufficient amount of an aqueous solution of a polyacrylamide in anionic form is added to the aqueous phase to result in at least 90 percent of the aluminum hydroxide settling in a time period of less than ten minutes at ambient conditions.
