Method and device for the continuous, single-step production of a homogeneous solution of cellulose in hydrous tertiary aminoxides

   
   

A method and a device for the continuous, single-step production of a homogenous solution of cellulose in hydrous aminoxides on the basis of cellulose and aqueous aminooxides, preferably N-methylmorpholino-N-oxide (NMMO), at temperatures in the range of from 50 to 130.degree. C. under a vacuum and water evaporation. The cellulose and the NMMO are dosed separately to the device, mixed while sheared, the water is evaporated until the mixture is dissolved, the solution is homogenized and directly fed to the consumer via screw conveyors, pumps and filters.

Un método y un dispositivo para la producción continua, single-step de una solución homogenous de la celulosa en aminoxides acuosos en base de la celulosa y los aminooxides acuosos, preferiblemente N-methylmorpholino-N-o'xido (NMMO), en las temperaturas en la gama de a partir del 50 a 130.degree. C. bajo un vacío y evaporación del agua. La celulosa y los NMMO se dosifican por separado al dispositivo, mezclado mientras que está esquilada, se evapora el agua hasta que se disuelve la mezcla, la solución se homogeneiza y alimentó directamente al consumidor vía transportadores, bombas y filtros del tornillo.
