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.
