Title

SYNTHESIS AND CHARACTERIZATION OF N-DIETHYL METHYL CHITOSAN

Pages

  431-436

Abstract

 CHITOSAN exhibits poor solubility at pH values above 6 that prevents enhancing effects at sites of absorption of drugs. In the present work, N-diethyl methyl CHITOSAN (DEMC) was prepared based on a modified two-step process via a 22 factorial design to optimize the preparative conditions. DEMC Polymer with different degrees of quaternization for pharmacological and pharmaceutical experiments were achieved. The reaction was optimized using different amounts of reactants. The pH-metric titration and infrared methods predetermined the degree of deacetylation of the starting CHITOSAN. DEMC Chloride was characterized using FTIR and 1H NMR spectroscopies. Based on NMR calculation, high degree of quaternization was achieved through the optimized two-step process. The prepared N-diethyl methyl CHITOSAN chlorides were rapidly and completely dissolved in water at room temperature.
