Abstract

Patente de Invenção:<B>"PROCESSO E APARELHO PARA A PREPARAçãO DE OXIáCIDOS DE FóSFORO A PARTIR DE FóSFORO ELEMENTAR"<D>. Processo para preparação de um oxiácido fosforoso compreendendo contato de fósforo elementar com água em presença de um catalisador eficaz para promover a oxidação de fósforo por reação com água. O uso de um catalisador de metal nobre, tal como, Pd sob agitação moderada e condições severas baixas é eficaz para preparação de oxiácido P(III) em seletividade alta. Outros metais de platina, e óxidos, sais, fosfetos e compostos de coordenação de metais de platina, metais do Grupo IB e matais do Grupo VIII, podem ser também usados como catalisadores. Vários aparelhos e esquemas de processo para preparação de ácido fosfórico e fosforoso são também revelados.
