Properties:Sodium formate, HCOONa, is the sodium salt of formic acid, HCOOH. It usually appears as a white deliquescent powder.
Sodium formate is used in several fabric dyeing and printing processes. It is also used as a buffering agent for strong mineral acids to increase their pH, as a food additive (E237), and as a de-icing agent.
In structural biology, sodium formate can be used as a cryoprotectant for X-ray diffraction experiments on protein crystals, which are typically conducted at a temperature of 100K to reduce the effects of radiation damage.
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. 3. In dyeing/Printing fabrics and paper. 4. Tanning of leather: Sodium formate stabilize the chromium, resulting in better leather quality. It is used for better penetration and tanning time reducing. 5. Deicing chemical: Sodium formate is less corrosive and undergoes fast melting action relative to other deicing chemicals. 6. Buffering agent: Sodium formate improves both desulfurization efficiency and increasing lime absorbent utilization. 7. Animal feed additive: Sodium formate is an efficient feed additive as it improve digestibility. 8. 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 Packaging:25/50/1000kgs bags or as customer's require
Storage:
Store in a cool, dry warehouse to prevent the hot and humid.
