Abstract: A method for recovery of a product fraction from a mixture comprising an impurity and linear alpha olefins, the method comprising: introducing the mixture into a distillation column, wherein an overhead stream is separated from a bottom stream, wherein the overhead stream comprises a Cn product, a Cn+x product, and an impurity, wherein n is an integer from 4 to 30, wherein x is an integer from 0 to 26; directing the overhead stream into a fractionation column; and separating a Cn product fraction and a Cn+x product fraction in the fractionation column, wherein the Cn+x product fraction comprises at least a portion of the impurity, wherein, when an amount of the impurity is greater than 1 part per million in the Cn+x product fraction, at least a portion of the collected Cn+x product fraction is recycled to the distillation column.

Abstract: A method for purifying 1-hexene is disclosed. The method can include contacting a first stream containing 1-hexene and 2-ethyl-1-butene with an isomerization catalyst containing an comprising an alumina, silica-alumina, a zeolite, or an ion exchange resin, or any combinations thereof, under conditions sufficient to selectively isomerize at least a portion of 2-ethyl-1-butene into 3-methyl-2-pentene and form a second stream containing 1-hexene and 3-methyl-2-pentene, and separating the second stream into a third stream containing 1-hexene and a fourth stream containing 3-methyl-2-pentene.
