- Abstract:
-
The oxidized acorn starch was prepared by using hydrogen peroxide as the oxidant agent and Cu(II)ions as the catalyst.The effects of pH,oxidant agent dosage,catalyst dosage,reaction temperature,andreaction time of the oxidation reaction were examined on the carboxyl percentage and the carbonyl percentageof the oxidized starch.The results showed that the oxidized acorn starch with 0.9140%carboxyl percentage U·sing 0.0524%of the catalyst dosage and with 0.9183%carboxyl percentage using 0.1244%of the catalystdosage,respectively,was obtained under such conditions of reaction as temperature being 45。C,time 3 h,pH=8,and 20%of hydrogen peroxide.
