    • There is provided a process for producing high-purity diisobutylene with a high reaction selectivity in which a mixed C4 fraction is contacted with an oligomerization catalyst to subject isobutene to oligomerization at one stage. The present invention relates to a process for producing diisobutylene by contacting a mixed C4 fraction as a raw material with a solid acid catalyst, which includes the steps of (a) isobutene oligomerization; (b) subjecting the resulting reaction products to distillation to separate the unreacted C4 fraction and an oligomer fraction including a C8 fraction produced from each other; and (c) purification of diisobutylene from the C8 fraction by distillation, in which a conversion of isobutene contained in the mixed C4 fraction upon conducting the step (a) is controlled to a range of from 60 to 95%.
    • 提供了一种生产具有高反应选择性的高纯度二异丁烯的方法,其中混合的C4级分与低聚催化剂接触以使异丁烯在一个阶段进行低聚。 本发明涉及通过使作为原料的混合C4馏分与固体酸催化剂接触来制备二异丁烯的方法,其包括以下步骤:(a)异丁烯低聚; (b)使所得反应产物蒸馏以分离出未反应的C4馏分和包含彼此产生的C8馏分的低聚物馏分; 和(c)通过蒸馏从C8馏分纯化二异丁烯,其中在步骤(a)中将混合的C4馏分中所含的异丁烯的转化率控制在60至95%的范围内。
