| titleOfInvention | Continuous production method of benzoin dimethyl ether and production device used for the method |
| abstract | The invention provides a preparation method and production equipment of benzoin dimethyl ether, and effectively solves the problems of low production efficiency, poor production stability and safety of the existing production method. The preparation method of the present invention comprises: (1) putting dioxane, benzil, and dimethyl sulfate into the mixing kettle respectively, opening and stirring to mix evenly, the mixing kettle is usually filled with frozen brine, and then the solid sodium methoxide and the above-mentioned materials are placed in the mixing kettle. Fast reaction in the pipeline reactor, the reaction temperature is controlled at 0 ℃ ~ 15 ℃; (2) the reacted material enters the receiving kettle, the receiving kettle directly removes the solvent dioxane through the thin film evaporator, and the removed solvent enters the dioxane Ring storage tank, the feed liquid directly flows into the alkaline washing kettle through the thin film evaporator; (3) The alkaline washing kettle is always prepared with dilute alkaline solution, which is kept at 60°C to 80°C. (4) Deionized water is added to the crystallization kettle, cooled to room temperature, and the material is cooled and crystallized to obtain the product benzoin dimethyl ether. |
