健化剂可分为均相催化剂和非均相催化剂两大类。在工业上所用的催化剂大部分是以无机物为主的非均相催化剂。最近十几年来出现了以有机金属化合物为主的均相催化剂。这种催化剂研究起来较方便,因其活性中心的结构容易搞清楚,而且几乎所有的金属原子都可以用于活性中心,改变配位体可以调节金属活性中心的立体效应或电子环境,因此活性和选择性较高。由于可用于均相催化剂的各种有机金属络合物的出现,过去不能合成的有机化合物,一个接着一个地被合成出来了。同时在工业上对石油化学工业和高分子化学工业起了很大的促进作用。近来在能源
Healthy agent can be divided into homogeneous catalyst and heterogeneous catalyst two broad categories. Most of the catalysts used in the industry are inorganic-based heterogeneous catalysts. In recent ten years there has been a homogeneous organometallic catalyst. This catalyst is more convenient to study because its structure of the active center is easy to understand and almost all the metal atoms can be used in the active center. Changing the ligand can regulate the stereoscopic effect or the electronic environment of the metal active center. Therefore, the activity and High selectivity. Due to the presence of various organometallic complexes that can be used in homogeneous catalysts, organic compounds that had not been synthesized in the past were synthesized one by one. At the same time in the industry on the petrochemical industry and polymer chemical industry has played a significant role in promoting. Recently in energy
