Problems solved by technology

[0005] Now, there is also a method that uses ethanol as a solvent to prepare sodium formate through the carbonylation reaction of carbon monoxide and sodium hydroxide at normal temperature and pressure, but the reaction speed is slow and the product yield is not high.
And there is no supporting production equipment, so it cannot be applied to industrial production

Description

Technical field [0001] The invention belongs to the technical field of chemical industry, and specifically refers to a device and method for synthesizing sodium formate. Background technique [0002] Sodium formate, chemical formula HCOONa·2H2O, slightly smell of formic acid. Easily soluble in water and glycerin, slightly soluble in ethanol. Melting point is 253°C (anhydrous), toxic. It is decomposed into hydrogen and sodium oxalate under strong heat. Used as camouflage acid in leather industry, chrome tanning method, used as catalyst and stabilizing synthetic agent, reducing agent in printing and dyeing industry, used in the production of sodium hydroxide, oxalic acid and formic acid. It is a white or light yellow crystalline solid at room temperature, slightly deliquescent. Slightly smell of formic acid. It is hygroscopic. At high temperature, it decomposes into sodium oxalate and hydrogen, and then produces sodium carbonate. Dissolved in about 1.3 parts of water. It is...
