production method | (1) is obtained by chlorination of glycerol. Glycerol and acetic acid were added to the reaction Pan, heated to 90-95 °c with stirring, and passed through dry hydrogen chloride gas until the reaction solution weight increased to 150% (theoretical value), which is the end point. The crude product was obtained by distillation under reduced pressure. After re-fractionation, the 128-132 °c (1.33-2.67kPa) fraction was collected to yield 3-chloro-1, 2-propanediol. (2) obtained by hydrolysis of epichlorohydrin. Epichlorohydrin was added into the reaction pot, stirred, diluted sulfuric acid was added to make the reaction solution acidic, and the temperature was raised and refluxed for 1H, and the obtained product was subjected to vacuum distillation to obtain a finished product. Raw material consumption quota: epichlorohydrin (>95%)1200kg/t, sulfuric acid 3kg/t. |
