The results show that the Co supported on Mg O presented excellent activity and stability.When the Co/Mg O catalyst with the Co content of 0.2 wt % (0.2%Co/Mg O) was used, 12.5% cyclohexane conversion and 74.7% selectivity to cyclohexanone and cyclohexanol (KA oil) were achieved under the reaction conditions of 0.5 MPa O and 140 °C for 4 an oxidant is a gas–solid–liquid reaction system, in which the reactants are difficult to turn into a product, leading to low conversion of cyclohexane generally.Even though significant progress has been made in the oxidation of cyclohexane with O, a high conversion of cyclohexane and high selectivity to KA oil is still a challenge, in which the key problem is to develop a highly efficient catalyst that is environmentally benign, low-cost and with easy separation.After being repeatedly used 10 times, its catalytic activity was hardly changed.

A quantitative formulation of color induction that also incorporates the dependence on (a) the photopic light adaptation level, (b) the angular size of the annular inducing stimulus, and (c) the time of fixation of the test field, is suggested.© 1974 Optical Society of America Full Article | PDF Article You do not have subscription access to this journal.Citation lists with outbound citation links are available to subscribers only.Currently, the commercial production of cyclohexane oxidation is processed at about 150 °C under 1~2 MPa oxygen atmosphere over the homogeneous cobalt salt catalyst, in which a low conversion (~4%) is obtained to avoid the formation of side products and to obtain a high selectivity (~85%) toward KA oil [5].Therefore, it is urgent to develop a new reaction process with a high cyclohexane conversion and high selectivity to KA oil. As a result, various kinds of catalysts have been developed based on the used oxidant and reaction system, such as metal coordination polymers [6,7,8,9,10], supported noble metals [11,12,13,14,15,16], supported metal complexes [17,18,19,20], metal doped-molecular sieves [21,22,23] and metal oxides [24,25,26].
