1-已烯是低密度聚乙烯合成的第二共聚单体。多数国家采用乙烯齐聚工艺路线制备1-已烯。其催化剂制备麻烦,选择性较低,工艺过程较复杂,不易工业化。国内尚处于实验室研制阶段,需要的1-己烯靠进口。根据中国的国情,有较丰富的正己醇来源,笔者进行了正己醇脱水制备正己烯的试探工 1-Hexene is the second comonomer for LDPE synthesis. Most countries use ethylene oligomerization process to prepare 1-hexene. The preparation of the catalyst is troublesome, the selectivity is low, the process is complicated and the industrialization is not easy. Domestic is still in the laboratory development stage, the need of 1-hexene by import. According to China’s national conditions, there is a richer source of n-hexanol, the author conducted a n-hexanol dehydration n-hexene to try
