| 摘 要： | 2,6二异丙基萘(2,6-DIPN)是一种重要的有机化工原料,可作为制备高性能聚酯-聚对萘二甲酸二乙酯(PEN)的原料.要满足生产聚酯对原料的高纯度要求(＞95%),必须对2,6-DIPN进行分离精制.综述了从二异丙基萘产品混合物中分离精制2,6-DIPN的方法,详细介绍了吸附分离法、络合分离法和高压结晶法,并指出了它们各自的优缺点及合理的提纯方向.

| Abstract: | As the material of poly (PEN), 2,6 - diisopropylnaphthalene (2,6 -DIPN) is a valuable compound. In order to provide the high purity (>95%) precursor for polymers, 2,6 -DIPN must be refined firstly. The refining methods of 2,6 -DIPN from the isomers of diisopropylnaphthalene were reviewed. The separation methods of adsorption, complex and crystallization with pressure were pointed out, and the specialties of each method and the suitable refining technology were discussed. |
