Sodium Formate is also called sodium formate. The crystal contains two crystal waters, so it is also called sodium formate dihydrate, sodium formate dihydrate, sodium formate dihydrate. Sodium formate is one of the simplest organic carboxylates. It is white crystals or powder with a slight Formic Acid odor. Slightly deliquescent and hygroscopic. Soluble in about 1.3 parts of water and glycerin, slightly soluble in ethanol and octanol, insoluble in ether. Its aqueous solution is alkaline. When heated, sodium formate decomposes into hydrogen and sodium oxalate, and then generates sodium carbonate. Sodium formate is mainly used in the production of insurance powder, oxalic acid and Formic ACID. In the leather industry, it is used as a camouflage acid in the chrome tanning process, used as a catalyst and a stable synthetic agent, and a reducing agent in the printing and dyeing industry. Sodium formate is harmless to the human body and has irritating effects on eyes, respiratory system and skin.
