摘要： 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.

摘要： A biological treatment system for removal of gaseous waste materials. The system comprises a column containing microorganisms which break down components of the waste materials; a pond in series with the column containing life forms in addition to the microorganisms in the column, which life forms provide essential nutrients for the microorganisms in the column; a treatment bed containing a reaction medium for removing undesirable biological metabolic by-products from the action of said microorganisms upon the gaseous waste materials; a fluid distribution means for circulating water between the pond, column and bed and a means for delivering gaseous waste materials through the column before such gaseous waste materials reach the pond.

摘要： This invention relates to an improvement to a process for synthesizing cellulose aminomethanate wherein cellulose is steeped in an aqueous urea containing solution, dried to form an intimate mixture of cellulose and urea of known composition, and heated to form the cellulose aminomethanate; the improvement comprising, heating the mixture to a temperature above about 125 degrees centigrade, measuring the weight loss of the mixture during heating, comparing the measured weight loss of the mixture during heating to the weight of an equivalent amount of ammonia released in accord with the reaction path:Cell-OH+CO(NH.sub.2).sub.2 .fwdarw.Cell-OCONH.sub.2 +NH.sub.3continuing heating until the total measured weight loss corresponds to the total weight of an amount of ammonia released in the reaction when from about 30 to about 100% of the total weight of urea present in the mixture reacts with cellulose. Cellulose aminomethanate manufactured in accord with this process, can be made having a uniform distributioon of substituent throughout the cellulose at the molecular level and comprises a consistently reproducable product for manufacturing sausage casing.

摘要： An improvement to the process for synthesizing cellulose aminomethanate is disclosed which comprises slurring cellulose in low concentrations of aqueous caustic solutions, in the presence of urea, and steeping the slurried mixture, at from about 2.degree. C. to about -15.degree. C., for a time sufficient to permit swelling of the cellulose and uniform distribution of the urea. Cellulose aminomethanate manufactured from product prepared in accord with this process, has a uniform distribution of aminomethanate throughout the cellulose at the molecular level and comprises a suitable product for manufacturing sausage casing.
