The hydrolysis reaction of acetic anhydride was enthalpically stabilized and entropically destabilized at mole fractions of acetonitrile greater than 0.17 and the reverse occurred at mole fractions less than 0.17. Activation enthalpy and entropy result in the reaction being less favorable to form ...
Cellulose is acetylated by contacting substantially dry fibres with acetic acid, limiting the amount of acid contained in the fibres to 10-60% by weight, by removal of excess acid if necessary; contacting the resulting swollen fibres with acetic anhydride at a temperature from ambient to 140 DEG...
