| Abstract: | The starch maleat ester was prepared from tapioca starch by esterification with maleic anhydride with microwave irradiation.It mainly discussed the influence of several important parameters to the product.These parameters were the molar ratio of tapioca starch to maleic anhydride,the amount of Na2CO3,the amount of water,and the reaction time as well as the power of microwave.It has been observed that the degree of substitution(D) was 0.369 when tapioca starch was 10 g,the molar ratio of starch to maleic anh... |
