    摘要： PURPOSE: A manufacturing method of chlorohydrins is provided to improve the yield and the selectivity of chlorohydrins and to prevent the reduction of reaction speed, without using a lot of chlorinating agent or catalyst. CONSTITUTION: A manufacturing method of chlorohydrins comprises: a first reacting step reacting polyhydroxy aliphatic hydrocarbon with a chlorinating agent; a water removal step separating water, discharged from the first reacting step, to a water-rich layer and water-poor layer; and a second reacting step reacting the reactant with the chlorinating agent or additional chlorinating agent; a step of obtaining chlorohydrins concentrates by purifying the reactant discharged from last reacting step among the plurality of reacting steps; and an additional step of removing a catalyst from the chlorohydrins composition to the form of alkali metal salt, by contacting the chlorohydrins composition with alkaline compound.

    摘要： PURPOSE: A method for preparing chlorohydrins is provided to reduce reaction time and to increase a reaction rate by increasing reactivity to chlorination of polyhydroxy aliphatic hydrocarbon such as glycerol. CONSTITUTION: A method for preparing chlorohydrins by the reaction of polyhydroxy aliphatic hydrocarbon with a chlorination agent comprises a step of irradiating ultrasonic waves to a reaction mixture during the reaction. The polyhydroxy aliphatic hydrocarbon is a C2-20 compound in which 2 or more of hydroxyl groups are bonded with other carbon atoms. The chlorination agent comprises hydrogen chloride gas or hydrochloric acid.
