| titleOfInvention | Method for producing dichloropropanol |
| abstract | Disclosed is a novel process which prevents contamination of dichloropropanol with hydrogen chloride and makes it possible to separate reaction products, water and dichloropropanol from unreacted raw materials. A) In a liquid reaction medium containing water in contact with the gas phase, glycerol is reacted with hydrogen chloride under a partial pressure of hydrogen chloride in the gas phase greater than 0.2 absolute bar; b) At least a part of the liquid reaction medium from step a) and optionally a part of the gas phase are subjected to at least one separation operation, and before said separation operation, said part of the liquid reaction medium from step a) and The gas phase portion is in bi) said portion of the liquid reaction medium to achieve a ratio below the weight ratio of hydrogen chloride to water in the binary azeotropic hydrogen chloride / water composition at the total pressure of the separation operation. At least one treatment to reduce the weight ratio of hydrogen chloride to water and / or bii) water and dichloromethane in a ternary water / dichloropropanol / hydrogen chloride azeotrope at the total pressure of the separation operation Heavy with propanol At least one method for producing dichloropropanol is subjected to treatment for lowering the weight ratio of water to dichloropropanol in the portion of the liquid reaction medium in order to achieve a ratio following ratio.
