均相催化剂与多相催化剂相比有许多优点,如在均相催化剂中,全部中心金属原子均参与构成活性种;具有确定均一的结构;催化剂浓度低,具有高活性、高选择性;反应条件温和;不存在扩散问题;传热易于解决等.但是,均相催化剂与产物的分离问题给工业生产带来了困难,特别是对产品沸点高的均相催化过程,显得更为突出,加之所用催化剂大多是贵重金属,因此,均相催化剂的分离回收一直是催化剂研究领域的一个热点.如均相催化多相化的研究,即通过高分子锚定,无机载体固定、双重固载及液相担载等方法,使均相催化剂多 Homogeneous catalysts have many advantages over heterogeneous catalysts. For example, in a homogeneous catalyst, all of the central metal atoms are involved in the formation of the active species, with a defined homogeneous structure, low catalyst concentration, high activity, and high selectivity. The reaction conditions Mild; there is no diffusion problem; easy to solve the heat transfer, etc. However, the separation of homogeneous catalyst and product problems to the industrial production has caused difficulties, especially for the high boiling homogeneous product of the catalytic process, it is even more prominent, coupled with the use of Therefore, the separation and recovery of homogeneous catalyst has been a hot topic in the field of catalyst research, such as the research of heterogeneous catalytic heterogeneity, that is, through the polymer anchoring, inorganic carrier fixation, double immobilization and liquid phase Loading and other methods to make homogeneous catalyst
