Abstract

Un processo continuo per la produzione di ossamide si basa sull'ossidazione, catalitica dell'acido cianidrico con ossigeno o aria in forte eccesso in una soluzione di nitrato di rame in acqua-acido acetico.Il processo è realizzato in un reattore tubolare verticale con riciclo continuo di parte della sospensione di ossamide dal fondo alla testa del reattore.
