Sodium formate CAS 141-53-7 (also known as formic acid sodium salt), also known as formic acid sodium salt, contains two crystalline waters in the crystal, hence it is also known as sodium formate dihydrate, sodium formate dihydrate, or sodium formic acid dihydrate. Sodium formate is the simplest organic carboxylate, which is a white crystal or powder with a slight odor of formic acid. Slightly deliquescent and hygroscopic. Easily soluble in approximately 1.3 parts of water and glycerol, slightly soluble in ethanol and octanol, insoluble in ether. Its aqueous solution is alkaline. When heated, sodium formate decomposes into hydrogen gas and sodium oxalate, followed by the formation of sodium carbonate. Sodium formate is mainly used for the production of insurance powder, oxalic acid, and formic acid. Used as a camouflage acid in the chrome tanning process in the leather industry, as a catalyst and stabilizing synthetic agent, and as a reducing agent in the printing and dyeing industry. Sodium formate is harmless to the human body and has irritating effects on the eyes, respiratory system, and skin. The molecular formula is CHO2Na, and the chemical structural formula is HCOONa, HCOONa · 2H2O.
