Formic acid（HCOOH）MF: HCOOH, MW: 46.03, colorless transparent liquid with a strong pungent acidic odor (similar to formic acid fumes). Naturally occurs in secretions of insects such as ants and bees, as well as certain plants. Its molecule contains an aldehyde group, exhibiting some properties of aldehydes—it can reduce silver ammonia solution to form a silver mirror and decolorize potassium permanganate solution. Formic acid exhibits typical carboxylic acid properties alongside strong acidity and reducing power, capable of undergoing aldol-like condensation reactions.

Chemical Raw Materials Sector:
– Synthesis of formic acid esters (e.g., methyl formate, ethyl formate) used as intermediates for solvents, fragrances, and plasticizers
– Preparation of formamide and dimethylformamide (DMF), widely employed as organic synthesis solvents
– Production of oxalic acid, urotropine, and other chemical products as key C1 chemical intermediates
Pharmaceutical and Pesticide Sector:
– HCOOH serves as an acidifying agent and solvent in synthesizing penicillin and cephalosporin antibiotics
– Preparation of intermediates for insecticides (e.g., pyrethroids), fungicides, and herbicides
Leather and Textile Industry:
– It functions as an acidifying agent and deliming agent, replacing sulfuric acid
– Used as a dyeing aid (pH regulator), wool shrinkage treatment agent, and reducing agent for vat dyes
Formic acid serves as a natural rubber coagulant to replace acetic acid;
Other Applications:
– HCOOH functions as a preservative and acidity regulator
– HCOOH serves as fuel for direct formic acid fuel cells (DFAFC);
– Used to remove rust and scale from metal surfaces.
