METHOD FOR PRODUCING DICHLOROPROPANOL FROM GLYCEROL WHEREIN THE GLYCEROL COMES EVENTUALLY FROM CONVERSION OF ANIMAL FAT IN BIODIESEL PRODUCTION

摘要

PROBLEM TO BE SOLVED: To provide a method for producing dichloropropanol from a starting material being glycerol obtained from a regenerable raw material such as a fat or an oil of vegetable or animal origin.;SOLUTION: The method for producing dichloropropanol comprises reacting glycerol being a crude or refined one with a chlorinating agent such as hydrogen chloride in the presence of a catalyst based on a 5 or 6C carboxylic acid, a fatty acid such as octanoic acid, a carboxylic acid such as glutaric acid or tri- or tetra-carboxylic acid, or a carboxylic acid derivative such as an adipic acid derivative.;COPYRIGHT: (C)2009,JPO&INPIT
