<P>PROBLEM TO BE SOLVED: To provide a continuous process for preparing an appropriate chlorohydrin. <P>SOLUTION: A composition includes water, hydrogen chloride, 1,3-dichloropropan-2-ol and 2,3-dichloropropan-1-ol. A continuous process for producing dichloropropanol, wherein glycerol, an ester of glycerol or a mixture thereof is reacted with a chlorinating agent and an organic acid in a liquid reaction medium whose steady-state composition comprises glycerol, an ester of glycerol whose sum content, expressed as moles of glycerol, is greater than 2 mol% and less than or equal to 30 mol%, the percentage being based on the organic part of the liquid reaction medium, can provide the composition including water, hydrogen chloride, 1,3-dichloropropan-2-ol and 2,3-dichloropropan-1-ol. <P>COPYRIGHT: (C)2013,JPO&INPIT |
