Abstract A process for preparing sodium biacetate features that in the absence of solvent, glacial acetic acid and sodium carbonate directly take part in reaction to obtain said sodium biacetate. The equipment for implementing said process has a dual-cylinder internal cavity whose dual cylinders are tangent, reversely rotating stirring axles at the circle centers of dual cylinders, and a cooling water channel between internal and external layers of main body. Its advantages are simple process, high productivity, low energy consumption and high yield up to 95-98%.
