Introduction of sodium formate

Sodium formate, slightly acid odor, soluble in water and glycerin, slightly soluble in ethanol. Melting point 253 ℃ (anhydrous), toxic, strong thermal decomposition of hydrogen and sodium oxalate. Sodium formate as leather industry, chrome tanning method of camouflage acid catalyst and stable synthetic agent for printing and dyeing industry, reducing agent for the production of sodium hydrosulfite, oxalic acid and formic acid.

Sodium formate room temperature is white or light yellow crystalline solid, slightly deliquescent, slight formic acid odor, hygroscopic. High temperature decomposition into sodium oxalate and hydrogen, followed by sodium carbonate. Dissolved in about 1.3 parts water, soluble in glycerine, slightly soluble in ethanol, octanol, and insoluble in ether, the aqueous solution was neutral, pH 7. The relative density of 1.92. M.p. 253 ℃. Irritation. Goods often containing two molecules of water of crystallization.

Sodium formate as leather industry, chrome tanning method of camouflage acid catalyst and stable synthetic agent for printing and dyeing industry, reducing agent for the production of sodium hydrosulfite, oxalic acid and formic acid. Metal precipitates, can be formed in the solution of trivalent metal complex ions. A buffer action, the pH can be corrected acid.

Sodium formate can also be used alkyd paints, plasticizers, high explosives, acid-proof materials, aviation lubricants, adhesives, additives.
