Abstract
Se divulga un método para la producción de carbamato de celulosa en fase acuosa que comprende los pasos de: a) disponer de materia prima de celulosa; b) disponer de urea; c) mezclar celulosa y urea para obtener una mezcla; d) someter la mezcla a una presión reducida de no más de 350 mbar(a); e) calentar la mezcla hasta una temperatura de 130 a 150ºC para someter a la celulosa a una reacción con la urea para formar carbamato de celulosa; f) liberar la presión; g) recuperar el carbamato de celulosa, y h) lavar el carbamato de celulosa con agua.
