Abstract

PURPOSE: To prepare a monoalkylene glycol in high yield at a low temperature in a short time without by-production of polyalkylene glycols, by reacting an alkylene carbonate with water in the presence of molybdenum as a catalyst.
CONSTITUTION: An alkylene carbonate such as the formula I (R1WR4 are H, alkyl, aryl, etc.) is reacted with water at the ordinary temperature to 180°C under a pressure of 0W30kg/cm2G in the presence of a molybdenum catalyst to give the compound of formula II. The molybdenum catalyst is, e.g. molybdenum metal and/or a molybdenum compound (e.g. potassium molybdate, sodium molybdate, etc.), and its amount is ordinarily 0.05W10mol% on the basis of the amount of the alkylene carbonate. The amount of water is a little excess to the stoichiometric amount for the alkylene carbonate. If the amount is decreased to the stoichiometric amount, the energy for the purification process can be reduced.
