Aerobic oxidation of cyclohexane catalyzed by metalloporphyrin

Source:Patent: CN1405131A; CN1191218C, ZL02139709.Author:GUO CANCHENG; LIU QIANG; LIU YANGLink:http://www.pss-system.gov.cn/sipopublicsearch/search/search/showViewList.shtml

Abstract:

The invention relates to a new process in which under the catalytic action of metal porphyrin the cyclohexane can be selectively oxdated by air and made into cyclohexanol and cyclohexanone. Under thecondition of 2-10 atm air, reaction temp. is 125-150 deg.C, it selects and uses micro-oxo double metal porphyrin and single metal porphyrin or their solid carrier as main catalyst, and uses transition metal salt or oxide as co-catalyst, the metal porphyrin can high-effectively and high-selectively catalyze oxidation of cyclohexane by using air in the biological concentratino as biological enzyme.The dose of metal porphyrin is small and said metal porphyrin can be repeatedly used, and said catalyst dose also is small, its catalystic effect is good, said catalyst can be used for making homogeneous catalysis, and after it is solid-carried, it also can be used for making heterogeneous catalysis.
