ABSTRACT:
This invention relates to an improvement to a process for synthesizing cellulose aminomethanate which comprises slurrying cellulose in an aqueous caustic solution, in the presence of urea; steeping the slurried mixture for a time sufficient to permit swelling of the cellulose for uniform distribution of the urea; and, neutralizing the caustic solution of the steeped slurry by treatment with an acid neutralizing solution. When cellulose aminomethanate is manufactured from product prepared in accord with this process, it has a uniform distribution of substituent throughout the cellulose at the molecular level and comprises a suitable product for manufacturing sausage casing.
