Preparation and Application of 3,5-Dinitrobenzoic Acid Ester of Starch
Abstract:
A novel starch derivative——3,5-dinitrobenzoic acid ester of starch(DNBZ-ST) with different degree of substitution(DS) was prepared by reaction of starch with 3,5-dinitrobenzoyl chloride. The structures of products were characterized by FTIR, elemental analysis, 13C NMR and TG. The best reaction conditions were given. The DNBZ-ST has a good adsorption property for creatinine. The highest adsorption capacity was 25.0 mg creatinine per gram of DNBZ-ST(DS=2.09) at 37℃, pH=7 and creatinine concentration in solution of 100 mg/L.
