摘要

"METHOD FOR PREPARING DICLOROPROPANOLS 1,3-DICLORO-2-PROPANOL AND 2,3-DICLORO-1-PROPANOL, AND APPLIANCE FOR CARRYING OUT THE METHOD". A highly selective catalytic hydrochloride method of glycerine and / or monochloropropanediols to dichloropropanol 1,3dichloro-2-propanol and 2,3-dichloro-1-propanol products performed in at least one continuous reaction zone at reaction temperatures in the range from 70 to 140 198 C and with continuous removal of reaction water, liquid feeds containing at least 50% by weight of glycerine and / or monochloropropanediols. The method may be performed in a continuous-operation single-stage circulation reactor or a cascade of liquid-gas type continuous-flow reactors.
