Abstract
"PROCESSO PARA EXTRAIR NáILON DOS MATERIAIS RESIDUAIS". A invenção refere-se a um processo para recuperar náilon de um material contendo náilon pelo contacto do material contendo náilon com um solvente contendo alcanol a temperatura elevada e a uma pressão maior do a pressão de equilíbrio do solvente contendo alcanol a temperatura elevada, dissolvendo deste modo o náilon no solvente contendo alcanol, removendo o náilon dissolvido contendo solvente contendo alcanol de quaisquer sólidos não dissolvidos e reduzindo a temperatura do náilon dissolvido contendo solvente contendo alcanol para precipitar o náilon dissolvido.
