Abstract
Procedimiento para disgregar materiales lignocelulósicos por cocción con una mezcla acidificada a base de 70 a 30 partes de agua y 30 a 70 partes de un disolvente orgánico, a presión y a una temperaturas en el intervalo de 160 a 210ºC, caracterizado porque se utiliza como disolvente orgánico un alcohol alifático de bajo peso molecular, soluble en agua, y como ácido un ácido orgánico, a saber, ácido oxálico, maleico, orto-ftálico, L-málico, succínico, nicotínico, salicílico o trifluoroacético, o un ácido fuerte tamponando con una de sus saltes tampón neutras, a saber, ácido clorhídrico, ácido sulfúrico, ácido nítrico o ácido fosfórico, o bien se utiliza como disolvente orgánico una cetona alifática de bajo peso molecular y como ácido uno de los ácidos fuertes anteriormente mencionados, se mantiene en pH de la mezcla acidificada en el intervalo de 1,7 a 3,5, y, después de una impregnación inicial del material lignocelulósico, se conservan las condiciones indicadas durante al menos 3 minutos,después de la cocción se extrae el líquido de cocción , se lava el residuo, se separan por destilación disolvente orgánico y productos de disgregación volátiles del líquido de cocción extraído y luego se condensan el disolvente y los productos de disgregación separados y se separan de la solución remanente en los productos de disgregación no volátiles.
