[0001] This utility model relates to the field of sodium methoxide production technology, specifically a gas-liquid contact distillation column for the alkaline process of sodium methoxide production. Background Technology

[0002] Sodium methoxide has a wide range of applications, mainly in the production of sulfonamide drugs. Sodium methoxide can be produced through the alkaline process, which includes the production of liquid or solid sodium methoxide. The process mainly includes alkali dissolution, distillation, reaction, distillation, and drying of liquid sodium methoxide. It has many advantages, such as good final product quality, safe and reliable process, and the ability to achieve fully automated continuous production.
