Abstract
Glycidyl ethers are made by dehydrohalogenating a chlorohydrin ether of an alcohol with an alkaline dehydrohalogenating agent in the presence of epichlorohydrin as a solvent. The said alcohol may be a mono-, di-, tri- or polyhydric alcohol, including dihydroxy alkyl ethers of dihydric phenols, examples being specified. The alcohol is reacted with epichlorohydrin in the presence of a condensation catalyst, such as a BF3 catalyst, to introduce at least one chlorohydrin ether group into the alcohol. The catalyst is deactivated by use of minute amounts of alkali and water. Then there is added to the chlorohydrin ether epichlorohydrin in the proportion of at least one mol of epichlorohydrin per mol of chlorohydrin ether, and up to 20 mols of epichlorohydrin can be used. The dehydrohalogenating agent is preferably caustic alkali, but alkali metal complexes and salts such as sodium silicate, sodium aluminate and sodium zincate are mentioned. The amount of alkali used is only a slight excess over that required to react with the chlorine of the chlorohydrin ether.
