Application of 22094-18-4, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 22094-18-4, name is 1,3-Dibromo-2,2-dimethoxypropane, This compound has unique chemical properties. The synthetic route is as follows.
Under a nitrogen atmosphere, a 5L three-neck flask was charged with a starting material, ethanesulfonamide (163.5 g, 1.5 mol).Anhydrous potassium carbonate (275.8g, 2.0mol) and anhydrous DMF (1L) were stirred for 30min.Then 1,3-dibromo-2,2-dimethoxypropane (SM) (259.9 g, 1.0 mol) was added,Stir for 30 min, then raise the temperature of the reaction system to 95-100 C.20-22 hours at this temperature,Then cool to room temperature.After that, the pH was adjusted to 2 to 3 with 0.1N HCl, and the mixture was stirred well for 2-3 hours. Then, 2L of water was added to the system to precipitate a lot of off-white solid, which was filtered and dried to obtain 134.1 g of a solid. The yield was 82.3. %.
The chemical industry reduces the impact on the environment during synthesis 1,3-Dibromo-2,2-dimethoxypropane. I believe this compound will play a more active role in future production and life.
