Process for producing a chlorohydrin, according to which (a) a multihydroxylated-aliphatic hydrocarbon, an ester of a multihydroxylated-aliphatic hydrocarbon, or a mixture thereof, is subjected to a reaction with hydrogen chloride in a reaction medium (b) continuous or periodic withdrawal from the reaction medium of a fraction comprising at least water, the chlorohydrin and hydrogen chloride, is carried out (c) at least part of the fraction obtained in step (b) is introduced into a distillation step wherein the ratio between the hydrogen chloride concentration and the water concentration of the fraction introduced into the distillation step is lower than the hydrogen chloride / water concentration ratio in the binary azeotropic composition hydrogen chloride/water at the temperature and pressure of the distillation. |
