三乙醇胺催化合成正丁基苯基醚

Catalytic Synthesis of n-Butylphenylether with Triethanol Amine

采用３．０ｇ三乙醇胺为相转移催化剂，在６．０ｇ氢氧化钠，１．０ｍｌ水存在下，将０．１ｍｏｌ苯酚和０．２ｍｏｌ溴丁烷回流反应２．０ｈ，得正丁基苯基醚，收率为９２．０％

This paper reported that with 3.0 g N(CH 2CH 2OH) 3 as phase transfer catalyst and in the presence of 6.0 g NaOH and 1ml H 2O, 0.1 mol PhOH reacts with 0.2 mol CH 3CH 2CH 2CH 2Br under reflux, after 2.0 h 92.0% PhOCH 2CH 2CH 2CH 3 could be obtained.
