Process for the preparation N-alkyl-N,O-diacetyl hydroxylamine

摘要

Process for the preparation of N-alkyl-N,O-diacetyl hydroxylamine, for instance N-methyl-N,O-diacetyl hydroxylamine, by catalytic reduction of a nitroalkane, for instance nitromethane, in the presence of acetic anhydride. As catalyst preferably a platinum on alumina catalyst is used. The invention provides a simple one-step process for the preparation of N- alkyl-N,O-diacetyl hydroxylamine in a relatively concentrated reaction medium.
