Synthesis and characterization of citric acid anhydride
摘要
Abstract
Citric acid anhydride was prepared in laboratory with anhydrous citric acid and acetic anhydride as starting materials. Effects of mole ratio of the reactants,reaction temperature and dosage of solvent on the conversion and the yield were investigated with titration method via single factor tests. Results indicated that the yield of citric acid anhydride is 88.8% at the suitable conditions as reaction temperature 52 ℃,reaction time 1.5 h,n(acetic anhydride)∶ n(citric acid)=1.2 ∶1 and n(acetic acid)∶ n(citric acid)=1.0∶1. Chemical structure of the product was characterized by FT - IR,1 H NMR and MS,and the results of characterization showed that the product is a five member cyclo-anhydride.关键词
