  • Method for controlling oxygen level during continuous xanthation of alkali cellulose
    Patent number: 4076934
    Abstract: The amount of oxygen present during the continuous xanthation of alkali cellulose with carbon disulfide is narrowly controlled by continuously purging the alkali cellulose with nitrogen prior to entry of the alkali cellulose into the xanthator. Preferably, the nitrogen is metered into the alkali cellulose near the bottom of the feeder hopper before being fed into the xanthator, thereby allowing air entrained therein to be displaced by the nitrogen as it transfuses through the alkali cellulose.
