    Abstract: The present invention provides the method for producing the alkyl glycidyl ether in the bipolar membrane electrodialyzer, including applying current to the composition (A) having a heterogeneous system (oil phase/aqueous phase) containing the chlorohydrin ether at a concentration of not less than 5% by weight, water, and the electrolyte in the electrodialyzer to convert the chlorohydrin ether to the alkyl glycidyl ether through the reaction with OH generated on the bipolar membrane and simultaneously to separate and collect the C1 side product in the form of HC1 (hydrochloric acid).

    Abstract: A process for producing a glyceryl ether which comprises supplying a compound represented by the general formula (I): (I) (wherein R represents a C1-20 hydrogen group in which part or all of the hydrogen atoms may have been replaced with a fluorine atom; OA's may be the same or different and each represents C2-4 oxyalkylene; and p is a number of 0-20) and water to a reactor and hydrolyzing the compound under such conditions that the water is in a subcritical or supercritical state. The process for glyceryl ether production includes: a step (1) in which the water is recovered from the reaction mixture resulting from the hydrolysis, regulated so as to have a pH of 3.5 or higher, and then supplied to the reactor; or a step (2) in which the water recovered from the reaction mixture resulting from the hydrolysis is filtered through a reverse osmosis membrane and the treated water obtained is supplied as recycle water to the reactor.

    Abstract: PROBLEM TO BE SOLVED: To provide an efficient method for producing a high-quality glyceryl ether using recycled water. SOLUTION: The method for producing the high-quality glyceryl ether comprises feeding a reactor with water and a glycidyl ether of the general formula(I)(wherein, R is a 1-20C hydrocarbon group with part or the total hydrogen atoms therein optionally substituted with fluorine atom(s); OA are same or different and each is a 2-4C oxyalkylene group; and p is 0-20) to hydrolyze the glycidyl ether under such conditions that the water is in a subcritical or supercritical state. This method involves the step of subjecting the water retrieved from the reaction mixture after hydrolysis reaction to filtration treatment with a reverse osmosis membrane and feeding the thus treated water into the reactor as recycled water.
