Abstract: Process for preparing a chlorohydrin, comprising the following steps: (a) a polyhydroxylated aliphatic hydrocarbon, an ester of a polyhydroxylated aliphatic hydrocarbon or a mixture thereof whose alkali metal and/or alkaline earth metal content is less than or equal to 5 g/kg, a chlorinating agent and an organic acid are reacted so as to give a mixture containing at least chlorohydrin and by-products (b) at least part of the mixture obtained in step (a) is subjected to one or more treatments in steps subsequent to step (a) (c) at least one of the steps subsequent to step (a) consists in oxidation at a temperature greater than or equal to 800° C.
