A method for the preparation of dichloropropanol in the form of 1,3-dichloro-2-propanol and 2,3-dichloro-1-propanol is characterized in that hydrochloric acid salinization is carried out by glycerin and gaseous hydrogen chloride under the catalysis of carboxylic acid, which is characterized in that at least one of the hydrochloric acid salinization reactions is carried out. The reaction zone is continuous at a reaction temperature of 70-140 ℃, and the liquid feed contains at least 50% by weight of glycerol by continuous removal of water from the reaction.<br>
