一、引言醇脱水、脱氢催化反应的较详细研究已达数十年,虽然积累的经验及数据巳较丰富,反应不算复杂,但迄今对反应机理及活性中心尚有争辩,即使对于同一种催化剂,亦是如此.我们认为反应机理可随催化剂及醇种类的不同而改变.但这并不妨碍我们从中抽取催化剂选择的共同原理.它对多相催化理论的发展及实际应用均有意义.本文讨论 I. INTRODUCTION More detailed studies on alcohol dehydration and dehydrogenation catalytic reactions have been carried out for several decades. Although the accumulated experience and data are abundant and the reaction is not complicated, so far the reaction mechanism and activity center have been contested. Even for the same In our opinion, the reaction mechanism may vary with the type of catalyst and alcohol, but this does not prevent us from extracting the common principle of catalyst selection, which makes sense for the development of the theory of heterogeneous catalysis and its practical application This article discusses
