| 摘要 |
The invention concerns a method for making a chlorohydrin including the following steps: (a) reacting a polyhydroxylated aliphatic hydrocarbon, an ester of polyhydroxylated hydrocarbon, or a mixture thereof, and a chlorinating agent and an organic acid to obtain a mixture containing chlorohydrin and chlorohydrin esters; (b) subjecting at least part of the mixture obtained at step (a) to one or more treatments in steps subsequent to step (a); (c) adding polyhydroxylated aliphatic hydrocarbon at least at one of the steps subsequent to step (a), so that it reacts, at a temperature not less than 20 °C, with the chlorohydrin esters so as to form at least partly polyhydroxylated aliphatic hydrocarbon esters. |
