Abstract

SìNTESE DE CAPROLACTAMA. A PARTIR DE LISINA Em várias modalidades, a presente invenção pode envolver um método de síntese de <244>-amino-<>-caprolactama. O método pode compreender o aquecimento de um sal de L-lisina em um solvente compreendendo um álcool. Em outras modalidades, a presente invenção pode envolver métodos para a síntese de e-caprolactama. Os métodos podem compreender o aquecimento de um sal de L-lisina em um solvente compreendendo um álcool e a desaminação do produto de reação. Em várias modalidades, a invenção pode incluir métodos de conversão de biomassa em náilon 6. Os métodos podem compreender o aquecimento de L-lisina em um solvente compreendendo um álcool para produzir <244>-amino-<>s-caprolactama, a desaminação para produzir <>-caprolactama e a polimerização em náilon 6,em que a L-lisina é derivada da biomassa. Em outras modalidades, a presente invenção pode incluir métodos de fabricação de náilon 6. Os métodos podem compreender a síntese de <>-caprolactama e, então, a polimerização, em que a <>-caprolactama é derivada de L-lisina.
