Sodium Formate

Sodium formate is a white water-absorbing powder or crystal with a slight smell of formic acid. Soluble in water and glycerin, slightly soluble in ethanol, insoluble in ether; its aqueous solution is alkaline.

Under normal circumstances, sodium formate is safe to store, has hygroscopicity, and is easy to deliquesce. Attention should be paid to moisture during storage and transportation. It does not change the product properties when it absorbs moisture and agglomerates. It can be used normally after crushing.

It is a white or light yellow crystalline solid at room temperature, slightly deliquescent. Slightly smell of formic acid. Hygroscopic. It decomposes into sodium oxalate and hydrogen at high temperature, and then generates sodium carbonate. The relative density is 1.92. Melting point 253°C. Irritating.

Used as a camouflage acid in the leather industry, in the chrome tanning process, as a catalyst and stabilizing synthetic agent, as a reducing agent in the printing and dyeing industry, for the production of insurance powder, oxalic acid and formic acid. Precipitation of precious metals. Complex ions of trivalent metals can be formed in solution. Has a buffering effect and can correct the pH of strong acids.

Used in alkyd resin coatings, plasticizers, strong explosives, acid-resistant materials, aviation lubricants, adhesive additives.
