ABSTRACT:
The invention relates to a process for the manufacture of glycidyl ethers of monohydric or polyhydric phenols with excess epichlorohydrin, wherein the monohydric or polyhydric phenols are reacted with excess epichlorohydrin, based on the phenolic hydroxyl group, in the presence of a catalyst specific for the formation of chlorohydrin ethers from phenols and epichlorohydrin, and of 0.2 to 8 % by weight of water, based on the reaction medium, until the conversion to chlorohydrin ethers is at least 10 %, preferably 50 - 90 %, based on the phenolic hydroxyl groups, and are then reacted by heating with 0.9 to 1.15 equivalents of a solid alkali metal hydroxide per phenolic hydroxyl group to give glycidyl ethers.
