| Abstract: | Highly substituted cationic starch was prepared by microwave radiation in dry process. In this preparation, starting materials mixed with high speed stirrer, potassium hydroxide used as catalyst and discontinuous heated by microwave radiation at temperature 60~85°C to give 0.35~0.50 degree of substitution cationic starch. The conversion of cationic reagent reached 95%. The product is soluble in water. It is pasted when it meets water. |
