Abstract

"PROCESSO PARA A PREPARAçãO DE MONOACILIDRAZINAS". Esta invenção fornece um processo conveniente para a preparação de monoacilidrazinas de ácidos carboxílicos ou seus sais e hidrazina ou hidrazina substituída na presença de uma 1,3,5-triazina substituída por pelo menos um cloro ou flúor. A monoacilidrazina resultante pode ainda ser convertida em uma diacilidrazina, ou repetindo-se efetivamente a reação, ou através da reação com um cloreto de ácido carboxílico.
