|Title:||Rapid starch acetylation at low temperature using iodine as catalyst|
|Abstract:||A method to prepare starch acetate using acetic anhydride (AA) is presented. The process was carried out at temperatures below 100 °C using iodine (I) as a catalyst. The effect of reaction temperatures, as well as AA/starch and I/starch weight ratio was analyzed. The results show that high degrees of substitution can be reached by this method and the initial amount of acetic anhydride has a substantial effect on reaction efficiency. For a weight ratio of acetic anhydride to native starch (AA/AN) equal to two, a substitution degree of 3 was reached for 30 min and 70 °C.|
