Reaction Conditions

Reaction Steps

A mixture of 87 grams (1.5 mols) of allyl alcohol and 1 milliliter of boron trifluoride-diethyl etherate is heated to 60° C. in a reaction vessel provided with reflux condenser, thermometer and dropping funnel. Within 45 minutes, 46.25 grams (0.5 mol) of epichlorohydrin are constantly added to said mixture. The reaction is exothermic. Thereafter the reaction mixture is rectified via a 40 centimeter silver-coated column, whereupon at first 55 grams of unreacted allyl alcohol are distilled off at 24° C. and a pressure of 15 millibars. By subsequent distillation at 0.08 millibars there are obtained 59.7 grams (79.3% of the theory) of (3-chloro-2-hydroxy-propyl)-allyl ether with a boiling point of 57° C. and a refractive index nD20 =1.4630.
