Abstract

"PROCESSO PARA A PREPARAçãO DE UMA SOLUçãO AQUOSA DE HIDROXILAMINA LIVRE". Uma solução aquosa de hidroxilamina livre é preparada pelo tratamento de um sal de hidroxilamónio com amónia por um processo em contracorrente em uma coluna de esgotamento, por um processo no qual a hidroxilamina é liberada e ao mesmo tempo a solução obtida é separada, por destilação, em uma solução aquosa de hidroxilamina e uma fração com sal. O novo processo pode ser levado a efeito de uma forma simples e suave e em larga escala. O perigo de decomposição é minimizado devido à baixa carga térmica, à baixa concentração de hidroxilamina e ao curto tempo de residência no processo.
