Method for converting polyhydroxylated aliphatic hydrocarbons into chlorohydrins |
| abstract |
The invention concerns a method for preparing chlorohydrin which consists in (a) reacting a polyhydroxylated aliphatic hydrocarbon, an ester of a polyhydroxylated aliphatic hydrocarbon, or a mixture thereof, with a chlorinating agent to obtain a mixture containing chlorohydrin, esters of chlorohydrin and water; (b) subjecting at least one fraction of the mixture obtained at step (a) to a distillation and/or stripping treatment to obtain one part concentrated in water, in chlorohydrin and in ester of chlorohydrin; (c) subjecting at least one fraction of the part obtained at step (b) to a separation process in the presence of at least one additive to obtain a portion concentrated in chlorohydrin and in esters of chlorohydrin and which contains less than 40 wt. % of water. |
