PROCESSO PARA A RECUPERACAO DE RODIO,QUE ESTA CONTIDO EM LIGACAO COMPLEXA COM UM COMPOSTO ORGANICO DE FOSFORO(III),NOS RESIDUOS DA DESTILACAO DE PRODUTOS DA SINTESEOXO

摘要

A process for the recovery of rhodium from distillation residues of crude products from the oxo synthesis with rhodium complexed with an organic phosphorous III compound comprising treating the said distillation residues with oxygen or an oxygen containing gas in the presence of an alkali metal salt of a monocarboxylic acid of 2 to 5 carbon atoms at 60 DEG to 120 DEG C. at atmospheric or elevated pressure to form a water-soluble rhodium compound and extracting the mixture with water to obtain an aqueous phase containing the water soluble rhodium compound in a very simple manner without any substantial loss of rhodium.
