【Abstract】 This paper deals with the dry method condition of making starch sodium alkenylsuccinate under the condition of microwave radiation. It mainly discussed the influences of several important parameters to the product. These parameters were the amount of dodecenly succinic anhydride, the amount of Na2CO3 and the amount of water added to the slurry as well as the reaction time, and the optimum conditions were obtained.更多还原
