Abstract

MéTODO PARA EXTRAçãO DE NáILON DE MATERIAIS DE RESìDUOS. A presente invenção refere-se a um método para recuperação de náilon a partir de um material contendo, náilon por colocação em contato do material contendo náilon com um solvente contendo alcanol, em temperatura elevada e em uma pressão mais elevada do que a pressão de equilíbrio do solvente contendo alcanol na temperatura elevada, por meio do que se dissolve o náilon no solvente contendo alcanol, remoção do solvente contendo alcanol contendo náilon dissolvido de quaisquer sólidos não dissolvidos, e diminuição da temperatura do solvente contendo alcanol contendo náilon dissolvido, para precipitar o náilon dissolvido.
