METHOD FOR DRY HYDROCHLORINATION OF MASS FROM GLYCEROL HYDROCHLORINATION WITH HYDROCHLORIC ACID AND DEVICE FOR DRY HYDROCHLORINATION OF MASS FROM GLYCEROL HYDROCHLORINATION WITH HYDROCHLORIC ACID

The invention relates to a method of dry hydrochlorination of mass from glycerol hydro¬ chlorination with hydrochloric acid and a device for dry hydrochlorination of mass from glycerol hydrochlorination with hydrochloric acid. According to the invention, in which the reaction of gaseous hydrogen chloride with non- reacted glycerol and monochlorohydrin isomers to a mixture of dichloropropanol isomers is carried out in a device for dry hydrochlorination in the pressure range of 5÷11 bar (a) at temperature of 120÷160°C, the method of dry hydrochlorination of mass from glycerol hydrochlorination with hydrochloric acid, consists in the following: the mass from glycerol hydrochlorination with hydrochloric acid is introduced into the dispersion zone of a device (1) for dry hydrochlorination, and the reaction is initiated by introduction of gaseous hydrogen chloride; a forced turbulent flow of the liquid mass with gaseous hydrogen chloride in the dis¬ persion zone is formed until a diphase mixture is obtained; the diphase mixture is introduced into the bubbling zone consisting of a column reac¬ tor (3) of the device (1), tangentially in relation to its internal circumference; gaseous hydrogen chloride bubbles are allowed to flow freely upwards in the bubbling zone of the device (1), in a column of liquid with a defined height, the mixture of dichloropropanol isomers obtained as a result of the reaction is carried off from the device (1 ). According to the invention, in which the reaction of gaseous hydrogen chloride with non- reacted glycerol and monochlorohydrin isomers to a mixture of dichloropropanol isomers is carried out in a column reactor (3), the device (1) for dry hydrochlorination of mass from glycerol hydrochlorination with hydrochloric acid, is characterized in that the device (1) includes a dispersion zone and a bubbling zone connected with it, while the bubbling zone consists of a column reactor (3).
