Effect of Wet and Dry Heat on Structure of Cellulose

Effect of Wet and Dry Heat on Structure of Cellulose SUMMARY Heating of cellulose (purified cotton and cuprammonium‐regenerated cellulose) under nitrogen in the presence of liquid water at 100° and at 150°C brought about a small amount of hydrolysis and some dehydration, the extent of which was directly proportional to the temperature. Heating in the absence of water caused a much greater amount of hydrolysis and dehydration, which was particularly marked at the higher temperature. Heating affects the amorphous regions of cellulose more than the crystalline regions; hence changes are more evident in the less crystalline regenerated cellulose than in purified cotton cellulose. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Food Science Wiley

Abstract

SUMMARY Heating of cellulose (purified cotton and cuprammonium‐regenerated cellulose) under nitrogen in the presence of liquid water at 100° and at 150°C brought about a small amount of hydrolysis and some dehydration, the extent of which was directly proportional to the temperature. Heating in the absence of water caused a much greater amount of hydrolysis and dehydration, which was particularly marked at the higher temperature. Heating affects the amorphous regions of cellulose more than the crystalline regions; hence changes are more evident in the less crystalline regenerated cellulose than in purified cotton cellulose.
