GENERAL DESCRIPTION & APPLICATIONS

Formamide, HCONH2 is an amide derived from formic acid, the simplest and lowest mole weight carboxylic acid in which a single hydrogen atom is attached to the carboxyl group (HCOOH). Amide is a group of organic chemicals with the general formula RCONH2 in which a carbon atom is attached to oxygen in solid bond and also attached to an hydroxyl group, where R is hydrogen in formamide. Formamide is an transparent hygroscopic oily liquid with an ammonia odor. It is soluble in water and alcohol; melting point 2.5 C, boiling 210 C. Formamide is obtained by heating ethyl formate with ammonia or by heating ammonium formate with urea. Formamide is used in the synthesis of medicine, pesticide, animal glue and other organic compound. It is used as a solvent which ionizes water-insoluble compounds. It is used as a softening agent for paper and fiber. It is widely used in the fields of the spice, dye, plastic as well as textile industries.
