Abstract

método de dissolver materiais lignocelulósicos. a invenção descreve soluções contendo celulose e um método de dissolver materiais lignocelulósicos. no método, o material lingocelulósico é posto em contato com um ácido conjugado, formado por uma base orgânica forte e um ácido mais fraco, sob condições que são condutoras e pelo menos uma dissolução parcial dos componentes celulósicos do material lignocelulósico. foi encontrado que é possível recuperar pelo menos uma porção da parte dissolvida do material lignocelósico pela dissociação pelo menos parcial do ácido conjugado. além disso, é possível recuperar pelo menos uma porção da base orgânica dissociada e o ácido, para formar um ácido conjugado da base e ácido recuperado, e para reciclá-lo para uso nas primeiras etapas do método.
