    • Process for manufacturing dichloropropanol according to which: a) in a liquid reaction medium containing water, which is in contact with a gaseous phase, glycerol is reacted with hydrogen chloride under a partial pressure of hydrogen chloride in the gaseous phase greater than 0.2 bar absolute, and b) at least part of the liquid reaction medium and optionally part of the gaseous phase from step (a) is (are) subjected to at least one separation operation and, prior to said separation operation, the part of the liquid reaction medium and the part of the gaseous phase from step (a) is (are) subjected to: bi) at least one treatment for reducing the weight ratio between the hydrogen chloride and the water in the part of the liquid reaction medium so as to attain a ratio less than or equal to the weight ratio between the hydrogen chloride and the water in the binary azeotropic hydrogen chloride/water composition at total pressure of the separation operation, and/or bii) at least one treatment for reducing the weight ratio between the water and the dichloropropanol in the part of the liquid reaction medium so as to attain a ratio less than or equal to the weight ratio between the water and the dichloropropanol in the ternary water/dichloropropanol/hydrogen chloride azeotrope at total pressure of the separation operation.
    • 制备二氯丙醇的方法,其中:a)在含有与气相接触的水的液体反应介质中,甘油与氯化氢分压在氯化氢分压 (b)至少部分液体反应介质和任选地来自步骤(a)的部分气相进行至少一次分离操作,并且在所述分离操作之前, 将来自步骤(a)的液体反应介质的一部分和气相的一部分进行:b1)至少一种处理,用于降低部分液体中氯化氢和水之间的重量比 反应介质中,以便在分离操作的总压力下获得小于或等于二元共沸氯化氢/水组合物中氯化氢和水之间的重量比的比率,和/或bii)至少 一种处理是降低部分液体反应介质中水与二氯丙醇之间的重量比,以获得小于或等于三元水/二氯丙醇/氯化氢中水与二氯丙醇之间的重量比的比率 在分离操作的总压力下共沸。
