Abstract

For producing solutions of cellulose in water-containing tertiary amine oxides from a suspension of cellulose in an aqueous solution of the tertiary amine oxide by supplying heat under reduced pressure, the suspension having a viscosity between 50 and 15,000 Pas.sec, measured in a relative system, is spread as a layer or film over a heating surface and transported until a homogeneous solution of the cellulose is formed, the feeding of the suspension and the take-off of the homogeneous solution being carried out continuously. These solutions can be produced in an indirectly heated vessel which is provided with a stirring device and can be evacuated and which is designed as a cylindrical container (2) with a centrally mounted stirrer shaft (7) and stirrer blades (8) attached thereto, the radial distance (13) of the stirrer blades (8) from the inside wall (1) of the container (2) being at most 20 mm, and an inlet (11) for the cellulose suspension being provided in the upper part of the container and an outlet (12) for the homogeneous cellulose solution being provided at the lower end. <IMAGE>
