  • Hazard Note:Extremely Flammable/Corrosive/Harmful
  • 方法一:四甲基乙烯是由丙烯二聚而得到的,在二聚釜中投入丙烯,加入均相配合催化剂,在搅拌下进行催化聚合反应,当釜内压力降到0.01MPa以下时,即将物料停止反应,油层进行粗蒸,除去三聚和四聚的产物即C 9 ~C 19 。烯烃,收集53~75℃的馏分为粗产物,其中主要是2,3-二甲基丁烯-1,然后进行催化异构化,反应温度控制在85~90℃,使其中产物转变为2,3-二甲基丁烯-2,即四甲基丁烯-2,再进行精馏,收集71~74℃馏分,即成品2,3-二甲基丁烯-2,剩下的为其他的副产物C 6 烯烃。在二聚反应中丙烯的单程转化率>;90%,二聚选择性为80%,异构化转化率为79%。
