초록
Sodium cellulosates of cotton fabrics were prepared by means of an ion exchange reaction between the preswollen cotton fabrics and various sodium alkoxides in corresponding alcohol; sodium methoxide in methanol, sodium ethoxide in ethanol, sodium n-butoxide in n-butanol and sodium n-propoxide in n-propanol. As a result, the degree of sodium metallation (mol/AGU) was remarkably enhanced by the addition of dimethylsulfoxide (DMSO) or pyridine to the system as a cosolvent. And the demetallation reaction was significantly affected by the degree of acidity, electron donating power, Taft polar substituent constant
