Abstract

"PROCESSO PARA MELHORAR O ìNDICE DE PUREZA DE COMPOSTOS DE HIDRóXIDO DE AMÈNIO QUATERNáRIO POR MEIO DE ELETRóLISE". A presente invenção refere-se a um processo para melhorar o índice de pureza de uma composição que compreende um composto de hidróxido de amónio quaternário, mediante eletrólise, usando membranas seletivas de cátions. O processo é particularmente adequado para melhorar o índice de pureza de uma solução aquosa que compreende hidróxido de tetrametilamónio que foi utilizado na produção de 4-aminodifenilamina, durante um número de ciclos de reação.
