摘要
2,6-二异丙基萘(2,6-DIPN)是一种重要的化合物,可用于制取高级聚酯材料和液晶聚合物。本文论述了由萘经选择性烷基化生成2,6-DIPN的研究进展,着重阐述了合成2,6-DIPN所用催化剂的研究;还总结了从异构体中分离2,6-DIPN的方法,并对吸附分离法做了详细阐述;指出由萘作原料,沸石分子筛作催化剂制备2,6-DIPN是石油萘生产的理想的技术方向。
The paper describes the research progress of the preparation methods of 2,6-diisopropylnaphthalene(2,6-DIPN) by the selective alkylation of naphthalene and propylene,and emphasizes on the research development of the catalyst of the synthesis.Subsequently introduces the separation technology of 2,6-DIPN from diisopropylnaphthalene mixtures,among which special details are given to the method of adsorption separation.The paper also points out that the ideal technology of petroleum naphthalene production is preparing 2,6-DIPN from naphthalene and propylene on the zeolite molecular sieve.
