  • Process for preparing low-viscosity, aqueous cellulose ether solutions
    Publication number: 20020168407
    Abstract: A process of preparing low-viscosity aqueous cellulose ether solutions is described. The process comprises: (a) dissolving high molecular weight cellulose ether in water to form a first solution; (b) admixing a catalytic amount of an acid into the first solution of step (a) to form a second solution; (c) subjecting the second solution of step (b) to high-frequency radiation having a frequency of 3 to 300,000 MHz, which results in raising the temperature of said second solution to a temperature of 60° C. to 150° C.; (d) cooling the frequency subjected second solution of step (c); and (e) neutralizing the cooled solution. Also described is a method of using the cellulose ether prepared in accordance with the method of the present invention as a coating material for solid pharmaceutical administration units, such as tablets.
