WebJun 18, 2010 · Bismuth and hafnium triflate catalyzed a polymerization mechanism similar to that of triflic acid but were more active despite their poor solubility. BiCl 3 and HfCl 4 were considerably less reactive and the polymerization kinetics were quite different from those of the metal triflate catalyzed polymerizations. Web选用稀土金属Y对焙烧镁铝水滑石催化剂进行掺杂改性,运用BET、CO2-TPD等分析手段对系列催化剂进行分析,并以丙酮缩合制异佛尔酮为探针反应,考察Y的掺杂改性对催化剂的催化性能的影响.研究结果表明:稀土金属Y作为焙烧镁铝水滑石催化剂的助剂,能够使焙烧镁铝水滑石催化剂的强碱中心得以充分暴露 ...
