| titleOfInvention | Preparation method of epichlorohydrin |
| abstract | The invention provides a preparation method of epichlorohydrin, which comprises the following steps: the method comprises the steps of feeding chloropropene and hydrogen peroxide reversely by using a fixed bed catalytic reactor, maintaining a solvent in a reaction bed layer containing a catalyst by utilizing the balance of solvent gasification and condensation, and reacting chloropropene and hydrogen peroxide in the reaction bed layer to generate epoxy chloropropane. The preparation method provided by the invention is beneficial to promoting the chloropropene and hydrogen peroxide to fully react in the reaction bed layer, so that the epoxy chloropropane with higher purity is generated, meanwhile, the potential safety hazard is reduced, the problem that the catalyst is difficult to separate in the slurry bed reaction process is solved, the temperature control problem in the traditional fixed bed reaction is overcome, the reaction and the separation are combined in a fixed bed reactor, and the epoxy chloropropane is prepared with simple flow, low energy consumption and high efficiency. |
