Description and Uses
Formamide is a colorless, viscous liquid with afaint ammonia odor. Molecular weight=45.05; Specificgravity (H2O:1)=1.13; Boiling point=(decomposes)210.5℃; Freezing/Melting point=2.5℃; Vapor pressure 50.1 mmHg at 30℃; Flash point=154℃. Autoignitiontemperature ≥500℃. Hazard Identification (based onNFPA-704 M Rating System): Health 2, Flammability 1,Reactivity 0. Good solubility in water.
Formamide is a good solvent for proteins and salts owing to its high dielectric constant. Its main applications are as a solvent in the chemical industry, as a softener for paper, as an intermediate for the manufacturing of formic acid and esters and hydrocyanic acid, and as a reaction medium.
