| Outline of Final Research Achievements |
Ferulic acid is a plant-derived aromatic hydroxy acids possessing antimicrobial and antioxidant activities. In this work, we have investigated the synthesis conditions of cellulose acetoxyferulate (AcFA-cell), with the aim of developing aromatic cellulose ester derivatives possessing thermoprocessibility, organosolubility, and amtimicrobial/antioxidiant activities. Acetoxyferulic acid (AcFA) was obtained by acetylation of ferulic acid by acetic anhydride. AcFA-cell with the maximum degree of substitution of 2.2 and molecular weight of 600,000 was obtained by esterification of cellulose and AcFA under heterogeneous condition using trifluoroacetic anhydride as the catalyst and reaction medium. AcFA-cell possesses thermoplasticity with the glass transition temperature of 150-170 ℃ and film-forming ability by solvent casting using chloroform as the solvent.
