Sodium formate

　　Main Uses

　　Chemical Intermediate: A key raw material for the preparation of formic acid (via acidification reaction); synthesis of oxalic acid (ethanedioic acid): sodium formate undergoes high-temperature dehydrogenation to generate sodium oxalate, which is then acidified to obtain oxalic acid: \(\ce{2HCOONa \xrightarrow{200-250℃} Na2C2O4 + H2↑}\) used in the production of sodium hydrosulfite, pentaerythritol, and other chemical products.

　　Leather and Textile Industry: Used as a reducing agent for chrome tanning agents in leather tanning to make leather soft and wear-resistant; used as a reducing agent and mordant in the printing and dyeing industry to help dyes adhere to fibers and improve dyeing uniformity.

　　Construction and Building Materials: Used as a concrete early strength agent and antifreeze agent to accelerate cement hydration reactions, improve early concrete strength, and lower the freezing point (suitable for winter construction).

　　Other Fields: Used in the pharmaceutical industry for synthesizing sedatives, preservatives, etc.; used as an additive in drilling fluids in oil drilling to regulate pH and inhibit harmful microorganisms; used as a preservative and acidulant in the feed industry (dosage must be controlled).
