PROBLEM TO BE SOLVED: To easily obtain a hydroxyether compound useful as a lubricant or the like without using an organohalide and generating salt or the like as by- product by reacting a specific alcohol with a carbonyl compound in a hydrogen atmosphere having a specific hydrogen pressure in the presence of a specific catalyst at a specific temperature, and thereafter, conducting hydrogenolysis of the thus obtained product. SOLUTION: This compound such as 1,3-dihexyl glyceryl ether is obtained by reacting (A) a polyhydric alcohol (except monohydric and dihydric alcohols) such as glycerol with (B) a carbonyl compound such as hexylaldehyde (C) in a hydrogen atmosphere having a hydrogen pressure of ordinary pressure to 2 Mpa, (D) in the presence of a palladium-based catalyst such as Pd-C, at 10-200 deg.C, and thereafter, conducting hydrogenolysis of the thus obtained product. In the above reaction, when the component B is added through dripping from the beginning, it is desirable to allow the component C to flow into the system and the reaction temperature is pref. 100-200 deg.C and reaction time pref. 2-25 h, and furthermore it is desirable that the dripping amount of the component B is 2-4 molar times the component A when it is a trihydric alcohol. |
