Kind Code:
A1
Abstract:
A method for producing diisobutylene by bringing a raw mixed C4 fraction into contact with a solid acid catalyst, the method being characterized by comprising: a step (a) for an oligomerization reaction of isobutene; a step (b) for distillation to separate an unreacted C4 fraction and an oligomer fraction including a generated C8 fraction; and a step (C) for distillation to purify the diisobutylene in the C8 fraction, the conversion rate of the isobutene in the mixed C4 fraction being controlled to a range 60-95%.
