| titleOfInvention | A kind of dibromoethane microchannel efficient synthesis process |
| abstract | The invention relates to a microchannel efficient synthesis process of dibromoethane. First, inject liquid bromine into the preheater to form bromine vapor; then inject bromine vapor and ethylene into the microchannel reactor for reaction to realize gas-phase homogeneous reaction; control the reaction residence time, reaction temperature and pressure; finally, in the microchannel reactor The finished liquid is collected at the outlet to obtain 1,2-dibromoethane. The method adopts a preheater to convert the liquid bromine into bromine vapor, forms a gas phase homogeneous reaction, improves the mass transfer capacity, increases the reaction contact area, shortens the reaction time to the minute level, and improves the reaction efficiency. In addition, the synthesis reaction is carried out without a catalyst, which reduces the production cost, and at the same time, the conversion rate of liquid bromine reaches a maximum of 100%, and the content of the prepared 1,2-dibromoethane reaches a maximum of 99.8%, The highest yield was 98.5%. At the same time, the synthesis reaction in the microchannel reactor can realize continuous production, and the production process is safe and controllable. |
