Quantitative Analysis of Triacetin in Filter Rod and Plasticizer

The triacetin in acetate filter rod and plasticizer was determined with oscillatory extraction and HPLC. Triacetin was extracted from filter rod or plasticizer with methanol under room temperature, then analyzed. The (recovery) was about 98.9% and the RSD was less than 2%. This method was suitable to fast analysis of triacetin in acetate filter rod.
