METHOD OF PRODUCING DICHLOROPROPANOLS FROM GLYCERINE Russian patent published in 2009 - IPC C07C29/62 C07C31/36 B01J12/00

Abstract RU 2356878 C2

FIELD: chemistry.

SUBSTANCE: present invention relates to the method of producing dichloropropanols 1,3-dichloro-2-propanol and 2,3-dichloro-1-propanol through hydrochlorination of glycerine and/or monochloropropanediols by gaseous hydrogen chloride with carboxylic acid catalysis. Hydrochlorination is carried out at least in a single continuous reaction zone at reaction temperature 70-140°C and continuous removal of reaction water by distillation at low pressure. The liquid raw material contains at least 50 wt % glycerine and/or monochloropropanediols. The invention also pertains to versions of the apparatus for realising the method of producing dichloropropanols.

EFFECT: target products with high output and high selectivity of the reaction system.
