Abstract

La presente invención proporciona un método para producir polisulfato de pentosán, incluyendo el método un primer paso de obtener un xilooligosacárido ácido de una materia prima derivada de plantas y un segundo paso de obtener polisulfato de pentosán del xilooligosacárido ácido. El primer paso incluye un paso de despolimerizar la materia prima derivada de plantas. El segundo paso incluye un paso de sulfatar el xilooligosacárido ácido. El método incluye además un paso de desacetilación en el que se agrega una base para alcanzar un pH de 11 o mayor. El paso de desacetilación es un paso efectuado después del paso de despolimerización. El método de producción de la presente invención puede proporcionar polisulfato de pentosán que tiene un bajo contenido de grupo acetilo y también produce de manera barata y eficiente polisulfato de pentosán con un alto rendimiento.
