Abstract

Cellulose triacetate (CTA) was prepared in the presence of mixture of acetic anhydride/acetic acid/H₂SO₄. The structure and properties of cellulose triacetate acetylation were determined by IR, ¹H-NMR, XRD, DSC and chemical analysis. The results showed that acetyl mass fraction of all CTA samples were at least 60%, the most active reaction position on the anhydroglulose unit was C-6. Compared with that of cellulose, the crystallinity of CTA was much lower, but the processability was improved a lot.
