摘要
Heats of immersion into a series of organic bases at 25℃ are reported for Polymer protected catalyst PVC-AlCl3. There is a good correlation between the heats of immersion of PVC-AlCl3 and thermochemical measurements of BF3 or SbCl5. The results have shown that the reaction of PVC-AlCl3 with various bases is essentially Lewis acid-base interaction and the surface acidity of PVC-AlCl3 is mainly attributed to Lewis acidity
