ABSTRACT:
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:
