Abstract
Formamide is made by the action of ammonia on an alkyl formate at a pressure exceeding atmospheric pressure. Liquid ammonia is preferably used, but gaseous ammonia or a strong aqueous ammonia may be employed; in the latter case more or less ammonium formate is formed at the same time. When the pressure is released the heat of the reaction serves to evaporate the alcohol formed, leaving a residue of nearly pure formamide. Methyl formate, which may be obtained by the action of carbon monoxide on methyl alcohol or as a bye-product in the catalytic hydrogenation of oxides of carbon to methyl alcohol, is the alkyl formate preferably employed. The alkyl formate may be produced in the same reaction chamber as the formamide by the action of carbon monoxide on methyl alcohol in the presence of an alkali metal or alcoholate; the ammonia required for the production of formamide being introduced at the same time or subsequently.
