Abstract

"MéTODO PARA O TRATAMENTO DE UM MATERIAL QUE CONTEM LIGNINA, PRODUTO, LìQUIDO IÈNICO E UTILIZAçãO DO MESMO". Expõe-se um método para o tratamento de um material que contém lignina, tal como polpa de madeira, bagaço e outros materiais derivados de plantas, que compreende contactar o material que contém lignina com um líquido iónico para extrair a lignina do mesmo. o líquido iónico é adequadamente um sal de imidazólio, triazólio, pirazólio, piridina, pirrolidínio, piperidina, amónio, fosfónio ou sulfónio substituído ou não-substituído de um sulfonato de arilo substituído ou não-substituído, tal como um sal de líquido iónico de um sulfonato de xileno.
