Abstract
Improved process for the production of 2,3-dichloro-1-propanol in high yield by chlorinating allyl alcohol with chlorine, which is characteristic in that the chlorination reaction proceeds by introducing simultaneously allyl alcohol and chlorine gas and optionally hydrogen chloride gas into the reaction system containing aqueous hydrochloric acid without necessity of extreme cooling and/or pressure.
Claims6
In a process for the production of 2,3-dichloro-1-propanol comprising reacting allyl alcohol and chlorine gas in aqueous hydrochloric acid, the improvement comprises using an aqueous solution of hydrochloric acid having a concentration of 25 to 40% by weight and carrying out the reaction of allyl alcohol and chlorine gas by supplying allyl alcohol and chlorine gas simultaneously to the reaction system.
