| titleOfInvention | A method of preparing halogen propyl alcohol and propylene oxide |
| abstract | It provides a kind of method for preparing halogen propyl alcohol, comprising the following steps: (1) halogen alcoholization: hydrogen halides, H being first added in reaction unit 2 O 2 , catalyst, after a period of time, be added propylene, carry out halogen alcoholization reaction and obtain halogen propyl alcohol.A kind of method that halogenohydrin method prepares propylene oxide is also provided, include the steps that claim 1 (1), it is characterized by: the method also includes: (2) are saponified: the hydroxide of the halogen propyl alcohol of step (1) and alkali metal being carried out saponification, separates and obtains propylene oxide and halogenated alkali metal salt；Optionally, (3) electrodialysis: the halogenated alkali metal salt that step (2) are obtained passes through bipolar membrane electrodialysis, obtains the hydroxide and hydrogen halides of alkali metal.Method of the invention prepares halogen propyl alcohol or propylene oxide with high selectivity and yield, and considerably reduces the discharge of waste water, waste residue. |
