Sodium formate
Classification :
PRODUCT DETAILS
Sodium formate;Formic acid sodium salt, also known as sodium formate, crystallization contains two crystal water, so also known as sodium dihydrate, sodium dihydrate, sodium formatehydrate.Sodium formate is the simplest organic carboxylate, white crystal or powder, slightly formic acid smell.Slightly deliquescence and hygroscopicity.Soluble in about 1.3 parts of water and glycerin, slightly soluble in ethanol, octanol, insoluble in ether.The aqueous solution is alkaline.When heated, sodium formate breaks down into hydrogen and sodium oxalate, which then forms sodium carbonate.Sodium formate is mainly used in the production of insurance powder, oxalic acid and formic acid.Used in leather industry as camouflage acid in chrome tanning process, catalyst and stabilizer, reducing agent in printing and dyeing industry.Sodium formate is harmless to humans and can irritate the eyes, respiratory system and skin.The molecular formula is CHO2Na, and the chemical structural formula is HCOONa, HCOONa·2H2O.

Application:
1)Raw material
Sodium formate chemically reduces other components by donating an electron or electrons. Formic acid and oxalic acid are prepared from sodium formate. Sodium formate is used in the manufacture of sodium hydrosulfite, a common reductive bleaching chemical.
2) Reductive bleaching agent
Sodium formate is used to improve the brightness and color in dyeing/printing fabrics and paper.
3) Tanning of leather
Sodium formate stabilize the chromium, resulting in better leather quality. It is used for better penetration and tanning time reducing
4) Deicing chemical
Sodium formate is less corrosive and undergoes fast melting action relative to other deicing chemicals.
5) Buffering agent
Sodium formate improves both desulfurization efficiency and increasing lime absorbent utilization.
6) Sodium formate is also used in liquid detergent as a builder or an enzyme stabilizer. It is used in dyeing, in electroplating, in silage preservation.
