| titleOfInvention | A new process for synthesizing dimethyldichlorosilane |
| abstract | The invention relates to a new process for synthesizing dimethyldichlorosilane by disproportionation of methylchlorosilane by-products. The method uses γ - Al2O3 immobilized AlCl3 as a catalyst, and simultaneously adds zinc chloride and tin chloride The mixture of methyltrichlorosilane and trimethylchlorosilane or low boiling is added to the raw material tank, fed to the preheating section with nitrogen gas, the temperature of the preheating section is 50‑200 °C, and the raw materials are vaporized here and enter the reaction section , the temperature in the reaction section is maintained at 200-400°C, and the reaction pressure is 0-0.6Mpa. The residence time is 10-40s. After the reaction, the product is cooled by the condenser, and the cooled monomer enters the collection tank, and the tail gas is absorbed by alkali solution. The advantage of the present invention is that the content of dimethyldichlorosilane synthesized by this process is higher than the level of existing patents and related documents, and this process is simple to operate, can effectively reduce the discharge of "three wastes", and can be used continuously on a large scale Chemical treatment of methylchlorosilane by-products. |
