Description
Formamidine acetate
It is obtained by condensation of triethyl orthoformate and glacial acetic acid by ammonia. Triethyl orthoformate was added to glacial acetic acid for heating, and reacted with ammonia for 1.5 h to precipitate white crystals, and then continue to pass ammonia for half an hour. The reactant was subjected to atmospheric distillation first, and then the alcohol was distilled off under reduced pressure and reduced pressure. Cold to 25 ° C, washed with anhydrous ethanol, filtered, dried to give methyl acetate.
