PURPOSE: To produce the titled substance in one step and high yield, by reacting allyl alcohol with epichlorohydrin and a solid alkali while removing produced water by the azeotropic distillation with epichlorohydrin.
CONSTITUTION: 1mol of allyl alcohol is made to react with 1W3mol of epichlorohydrin in the presence of a solid alkali in a binary phase comprising a solid phase and a liquid phase under boiling to obtain the objective substance. The produced water is removed from the system by forming an azeotropic mixture with the epichlorohydrin used as a raw material. The reaction temperature is preferably 30W60°C, and the reaction pressure is controlled (generally 40mmHgW 1atm) so as to keep the boiling state at the above temperature. The reaction mixture may be added to 0.1W3.0g of an organic amine, a quaternary ammonium salt (e.g. tetramethylammonium chloride), etc. per 100g of allyl alcohol.
