Use

It is colorless, odorless and oily liquid with slight ammonia-odor when containing impurities. It has hygroscopicity property. It has a relative molecular mass of 45.04. It has the relative density being 1.1334, the melting point being 2.55 ℃, the boiling point being 210.5 ℃, the refractive index being 1.4475, the flash point being 154 ℃ and the viscosity being 3.76mPa ? s (20 ℃). It is insoluble in ether and chlorinated solvents, slightly soluble in benzene and is miscible with water, methanol, ethanol, acetic acid, acetone, dioxane, ethylene glycol, phenol and low grade ester. This product can dissolve the casein but does not dissolve albumin. This product can dissolve casein, dextrose, corn protein, gelatin, glue, resin, starch, lignin, cellulose acetate, nylon, and some inorganic salts: the chloride compounds of copper, lead, zinc, tin, cobalt, iron, aluminum and nickel and also some kinds of sulfates and nitrates. At room temperature, formamide has a low hydrolysis rate. Raising the temperature or the addition of acid, alkali can all accelerate the hydrolysis rate. In the presence of a catalyst, being heated to less than 35 ℃ can decompose and release hydrogen cyanide. Formamide contains two active functional groups, namely the carbonyl and amide groups. It is easy to have chemical reaction to produce a lot of nitrogen-containing heterocyclic compound. Formamide can also react with a mineral acid to generate formic acid and ammonium salt. In the presence of a catalyst, it can react with organic halide or alcohol to form formic esters. This product can also react with β-diketone, β-imino ketone, aliphatic acyloin, arene acyloin as well as heterocyclic acyloin. It can also form complex with cobalt, copper and nickel salts. Formamide, in case of strong dehydrating agent such as phosphorus pentoxide, it can generate hydrogen cyanide. It can react with phosphorus pentasulfide to generate sulfur formamide. Formamide has strong corrosion effect on copper, brass, lead and rubber, therefore the storage and transportation should be paid attention. The main purposes: formamide can be used as the softener and solvent of animal glue and paper. It can also be used as the solvent of the spinning of the acrylonitrile copolymer, the polymerization of unsaturated amine polymerization and the production of pharmaceuticals as well as the solvent for extraction of grease and the dissolving items mentioned above. As intermediates, it can be applied the synthesis of imidazole, pyrimidine, 1, 3, 5-triazine, caffeine, theophylline and theobromine. Furthermore, it can also be used as the raw material of making dyes, spices, paints, adhesives, textile and paper treatment agent as well as the production of formic acid, dimethyl formamide and so on.
