    • PURPOSE: A method for preparing glycidyl ether compound is provided, to improve the production yield without a solvent by controlling the content ratio of an alcohol, epichlorohydrin, a phase transfer catalyst and an alkali metal a base. CONSTITUTION: The method comprises the steps of reacting an alcohol with epichlorohydrin without a solvent in the presence of an alkali metal base and an ammonium-based phase transfer catalyst. Preferably the glycidyl ether compound is an alkyl glycidyl ether represented by the formula 1a or a 1,3-dialkoxy-2-propanol represented by the formula 1b, wherein R1 and R2 are independent each other and is a saturated or unsaturated alkyl group or aromatic group containing the carbon chain or the carbon fluoride chain. Preferably the alcohol is primary, secondary or tertiary alcohol containing a saturated or unsaturated alkyl group of an aromatic group. The phase transfer catalyst is selected from an amine compound and an ammonium compound. The ratio of an alcohol, epichlorohydrin and a base is 1 : 0.8-4 : 0.8-4 by mol in the case of alkyl glycidyl ether of the formula 1a. And the ratio of an alcohol, epichlorohydrin and a base is 1 : 0.12-0.7 : 0.2-4 by mol in the case of 1,3-dialkoxy-2-propanol of the formula 1b. The ratio of a phase transfer catalyst to an alcohol is 0.0005-0.1 by mol.
    • 目的:提供缩水甘油醚化合物的制备方法,通过控制醇,表氯醇,相转移催化剂和碱金属碱的含量比,提高无溶剂的产率。 构成:该方法包括在碱金属碱和铵基相转移催化剂存在下,不用溶剂使醇与表氯醇反应的步骤。 优选地,缩水甘油醚化合物是由式1a表示的烷基缩水甘油醚或由式1b表示的1,3-二烷氧基-2-丙醇,其中R 1和R 2彼此独立并且是饱和或不饱和的烷基或芳族 含有碳链或碳氟链的基团。 优选地,醇是含有芳族基团的饱和或不饱和烷基的伯,仲或叔醇。 相转移催化剂选自胺化合物和铵化合物。 在式1a的烷基缩水甘油醚的情况下,醇,表氯醇和碱的比例为1:0.8-4:0.8-4摩尔。 在式1b的1,3-二烷氧基-2-丙醇的情况下,醇,表氯醇和碱的比例为1:0.1-0.7:0.2-4摩尔。 相转移催化剂与醇的比例为0.0005-0.1摩尔%。
