PROCESS FOR PRODUCING BUTENE OLIGOMER

摘要

A process for producing a butene oligomer which comprises: polymerizing a butane/butene mixture fraction in the presence of an acid catalyst to yield oligomers; and then either (1) fractionating the oligomers by distillation to obtain a desired fraction and subjecting the fraction to hydrogenation and then deodorizing treatment or (2) hydrogenating the oligomers, subsequently fractionating the oligomers by distillation to obtain a desired fraction, and deodorizing the fraction. By this process, a butene oligomer which is odorless and has excellent oxidative stability can be produced.
