摘要
本文报道了一种合成二缩水甘油醚的简便方法。不同于 Bartok 综述中的常规合成法,本法使用相转移催化剂,避免了常规方法中试剂前处理工作,并且将合成路线简化为一步.此法合成的乙二醇二缩水甘油醚和丁二醇二缩水甘油醚产率分别为33.4%和40.7%。气相色谱和色质联用谱分析粗产物发现相转移催化法合成产物主要是二缩水甘油醚。红外光谱分析也印证了色质联用谱结果。
One step synthesis of diglycidyl ethers using phase transfer catalyst without pretreatment of the reactants is reported.The yields of ethylene glycol digly- cidyl ether and 1,4-butylene-glycol diglycidyl ether prepared by this method were 33. 4% and 40. 7%,respectively.The components of their raw products were studied by gas chromatography and gas chromatography-mass spectrometry.It was found that products were mainly the diglycidyl ethers without trace of non-glycidyl ether chain extension products found in BF_3·Et_2O/KOH method.The IR spectra was well ac- cordant with the results of GC/MS spectra.
