概述据了解,现在世界上每年有二千万吨有机化学产品是用均相催化反应生产的。均相催化反应具有活性高,条件温和、选择性好和易于研究的优点。但是,也存在难以将产物从催化剂和溶剂中分离的缺点。所以工业上往往采用多相催化反应。涉及烯烃和双烯烃的某些较重要的均相催化反应参见图1。 Overview It is understood that twenty million tons of organic chemicals are produced by homogeneous catalysis in the world each year. Homogeneous catalysis has the advantages of high activity, mild conditions, good selectivity and easy to study. However, there is also the disadvantage that it is difficult to separate the product from the catalyst and the solvent. Therefore, industrial heterogeneous catalytic reactions are often used. See Figure 1 for some of the more important homogeneous catalytic reactions involving olefins and diolefins.
