| Abstract: | PVC-Pyridine resin was prepared, and its structure was characterized by IR spectra and elementary analysis. The flavor ethylbenzonate was prepared under PVC-Pyridine resin catalysizing. The influence factors for esterification reaction,such as catalyst quanitiy, raw material rations and reaction time were discussed. The results indicated that more than 97 % yield was obtained. |
