Abstract] Birnessite-type manganese oxides ME-OL-IS(Me: K, Mg, Fe, Ni and Cu)were
synthesized by static hydrothermal method and characterized by XRD and ICP-AES. The oxides were
used in the disproportionation decomposition of ter-butyl hydroperoxide(TBHP)to ter-butyl alcohol
The effects of reaction temperature, reaction time and catalyst dosage were investigated. The results
showed that all the ME-OL-I catalysts had the catalytic activity under mild reaction conditions(323-338
K and the activity of the CU-OL-1 catalyst was the highest. The conversion of TBHP and the selectivity
to tert-butyl alcohol reached more than 96 and 100% under the conditions of 65%(w)BHP aqueous
solution I ML, reaction medium acetonitrile 5 ml, the CU-OL-I catalyst dosage(based on the total
volume of TBHP aqueous solution and acetonitrile)1.67-8.33 m/ML, 338K and 1 h
