Preparation and Characterization of Chitin Benzoic Acid Esters

Chitin benzoic acid esters were prepared using a phosphoryl mixed anhydride method. The products were characterized by (1)H-NMR and FT-IR spectroscopy. FT-IR analysis revealed that the degree of O-acyl substitution of the products was in a range of 1.17–1.83. Morphological surface changes in the par...

Sumario:Chitin benzoic acid esters were prepared using a phosphoryl mixed anhydride method. The products were characterized by (1)H-NMR and FT-IR spectroscopy. FT-IR analysis revealed that the degree of O-acyl substitution of the products was in a range of 1.17–1.83. Morphological surface changes in the parent molecule due to the introduction of benzoic acid moieties were observed by scanning electron microscopy. The surface of the products was porous, in contrast to the sheet-shape of the parent molecules. The solubility of the products, which improved with increased degree of acid substitution, was tested in various organic solvents.
