METHOD AND DEVICE FOR THE CONTINUOUS, SINGLE-STEP METHOD AND DEVICE FOR THE CONTINUOUS, SINGLE-STEP PRODUCTION OF A HOMOGENEOUS SOLUTION OF CELLULOSE PRODUCTION OF A HOMOGENEOUS SOLUTION OF CELLULOSE IN HYDROUS TERTIARY AMINOXIDES IN HYDROUS TERTIARY AMINOXIDES

摘要

The invention relates to a method and to a device for the continuous, single - step production of a homogeneous solution of cellulose in hydrous aminoxides on the basis of cellulose and aqueous aminoxides, preferably N- methylmorpholino-N-oxide (NMMO), at temperatures in the range of from 50 to 130 ~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.
