METHOD FOR PREPARING 1,3-DICHLOROPROPANOL-2 Russian patent published in 2005 - IPC

Abstract RU 2263656 C1

FIELD: organic chemistry, chemical technology.

SUBSTANCE: invention relates to the improved method for preparing 1,3-dichloropropanol-2 (α-dichlorohydrin-glycerol) used in producing glycerol fats, plastic masses and putties. Method involves hydrochlorination reaction of epichlorohydrin with gaseous hydrogen chloride carried out in reactor at temperature 20-25°C and this hydrochlorination reaction is carried out in the presence of saturated calcium chloride solution in water in the amount from 0.03% to 0.04% (by mass) of epichlorohydrin mass, volume rate feeding hydrogen chloride from 900 h^-1 to 1000 h^-1 and the equimole ratio of epichlorohydrin to hydrogen chloride. Method provides 99.4% yield of 1,3-dichloropropanol-2, to simplify technology due to the complete conversion of parent reagents and to exclude the recirculation stage of hydrogen chloride.

EFFECT: improved preparing method.
