Chemical property

This product can dissolve casein, but not albumin. It can also dissolve casein, glucose, zein, gelatin, animal glue, resin, starch, lignin, acetate fiber, nylon, and certain inorganic salts: chlorides of copper, lead, zinc, tin, cobalt, iron, aluminum, and nickel, certain sulfates, nitrates. At room temperature, the hydrolysis rate of formamide is very slow, and the hydrolysis can be accelerated by increasing the temperature or adding acids and bases. In the presence of catalyst, heating to below 35℃, hydrogen cyanide can be decomposed. Formamide has two active functional groups, namely carbonyl group and amide group, which are easy to chemical Chemicalbook reactions and generate many nitrogen-containing heterocyclic compounds. Formamide can react with inorganic acids to form formic acid and ammonium salts. In the presence of catalyst, it reacts with organic halides or alcohols to form formates. This product can also react with β-dione, β-imidone, aliphatic azoin, aromatic azoin, heterocycloin. It can be combined with cobalt salt, copper salt and nickel salt to form complex. When formamide meets with strong dehydrating agent such as phosphorus pentoxide, hydrogen cyanide can be formed. It reacts with phosphorus pentasulfide to form thioformamide. Formamide can strongly corrode copper, brass, lead and rubber, so it should be paid attention to when storing and transporting.

Purpose

Formamide is used as a softener and solvent for animal glue and paper, for spinning acrylonitrile copolymer, unsaturated amine polymerization, solvent in pharmaceutical production, solvent for purifying oil and the above mentioned dissolution projects. Used as an intermediate to synthesize Chemicalbook imidazole, pyrimidine, 1, 3, 5-triazine, caffeine, theanine, theobromine. Used as raw materials for dyes, spices, pigments, adhesives, textile additives, paper treatment agents, etc. Raw materials for the production of formic acid and dimethylformamide.
