Abstract

"COMPOSIçõES MULTICOMPONENTES CONTENDO QUITOSANA E MéTODOS PARA PREPARAR AS MESMAS". Um método para preparar sais multicomponentes de um composto em solução aquosa inclui as etapas de primeiro selecionar pelo menos um ácido fraco, então selecionar pelo menos uma primeira base fraca, misturar uma quantidade molar equivalente do ácido fraco com a base fraca em água para formar uma solução aquosa, adicionar pelo menos uma segunda base fraca à solução e, finalmente, misturar a solução aquosa para produzir uma composição de sal multicomponente.
