Product Detail

Formic acid is an organic substance, commonly known as formic acid, which is the simplest carboxylic acid. It is a colorless and pungent liquid. AC is a weak electrolyte, but its aqueous solution is weakly acidic and corrosive, and can stimulate skin blistering. It is commonly found in the secretions of bees, certain ants, and caterpillars. It is an organic chemical raw material and is also used as a disinfectant and preservative.

1. Leather processing: Formic acid is one of the important chemicals in the leather processing industry. It can be used in processes such as hair removal, catalytic dyeing and tanning.

2. Chemical synthesis: Formic acid is an important raw material for the synthesis of other chemicals. It can be used to prepare formate, acetic acid, formaldehyde, acetaldehyde and other organic compounds, which are widely used in medicine, agriculture, cosmetics, plastics and chemical industries.

3. Catalyst: chemical formic acid can be used as a catalyst to catalyze esterification and dehydration reactions. It can accelerate the progress of various chemical reactions, and improve the efficiency and yield of the reaction.

4. Preservatives and flame retardants: Formic acid has antibacterial and antifungal effects, so it can be used as a preservative to extend the service life of the product. In addition, formic acid also has certain flame retardant properties, which can be used to increase the fire resistance of materials.

5. Water treatment: Formic acid can be used as a water treatment agent to purify, regulate water quality and control the growth of microorganisms in water.
