(Colussi et al., 2015). Acetylation using acetic anhydride at the concentration of 10% at the pH of 8.5 had been successfully applied to improve the physicochemical properties ofjack beanstarch (Betancur et al., 1997). After a 30-min reaction, the acetyl value reached 2.34%, and thus the...
Acetylation involves the reaction of hydroxyl groups with acetic anhydride (or acetyl chloride) to form acetate esters. In the case of glucose, all five hydroxyl groups will react with acetic anhydride to form glucose penta-acetate. Step 4: Drawing the Structure of Glucose Penta-Acetate1. Start...
