<p>A method for producing a glyceryl ether, including the steps of feeding a compound represented by the general formula (I):
wherein R is a hydrocarbon group having 1 to 20 carbon atoms, a part or all of the hydrogen atoms of which may be substituted with a fluorine atom; OA, which may be identical or different, is an oxyalkylene group having 2 to 4 carbon atoms; and p is the number of from 0 to 20,
and water to a reactor, and subjecting the compound to a hydrolytic reaction under conditions that water is in a subcritical state or a supercritical state; and wherein the method includes the step of (1) collecting water from a reaction mixture after the hydrolytic reaction, adjusting a pH of the water to 3.5 or more, and feeding the collected water to the reactor; or (2) subjecting water collected from a reaction mixture after the hydrolytic reaction to a filtration treatment with a reverse osmosis membrane, and feeding the resulting treated water as a recycled water to the reactor.</p> |
