Abstract

Alkylation of phenol with tert-butanol in a displacement draining-film reactor on a heterogeneous catalyst, Beta zeolite, was studied. Optimum process conditions ensuring the maximal p-tert-butylphenol yield were determined: phenol : tert-butanol molar ratio (3–3.5) : 1, superficial liquid velocity 1.0–1.5 m³ m^–2 h^–1, and temperature 100–110°C. A procedure ensuring 100% conversion of tert-butanol and isobutylene (a by-product formed from tert-butanol) was suggested.

苯酚与叔丁醇在排水膜反应器中烷基化

摘要

研究了在多相催化剂 Beta 沸石上的置换排水膜反应器中，苯酚与叔丁醇的烷基化反应。确定了确保最大对叔丁基苯酚产量的最佳工艺条件：苯酚：叔丁醇摩尔比 (3–3.5) : 1，表观液体速度 1.0–1.5 m ³ m ^–2 h ^–1和温度 100–110 ℃。建议采用确保叔丁醇和异丁烯（由叔丁醇形成的副产物）100% 转化的程序。
