Abstract

PROCEDIMIENTO PARA PREPARAR UN COMPUESTO DE CELULOSA SOLUBLE EN ALCALIS. SE HACE REACCIONAR CELULOSA CON UREA A TEMPERATURA ELEVADA, TRATANDO LA CELULOSA CON UREA DISUELTA EN AMONIACO LIQUIDO, PENETRANDO EL AMONIACO EN LA CELULOSA A LO LARGO DE SUS ELEMENTOS CRISTALINOS Y LLEVANDO A LO LARGO DE LOS MISMOS LA UREA DISUELTA, TRAS DE LO CUAL LA UREA SE SEPARA POR EVAPORACION, Y LA CELULOSA CONTENIENDO UREA SE CALIENTA A UNA TEMPERATURA SUFICIENTEMENTE ALTA PARA LA REACCION ENTRE LA CELULOSA Y LA UREA, FORMANDO ASI CARBAMATO DE CELULOSA SOLUBLE EN ALCALIS.
