As seen from Trials 3, 5 and 6, the use of Mn–Co in Trial 6 produced a 100%cyclohexane conversion, which indicated that Mn–Co works as a better catalyst pair in terms of catalytic activity. Mn was not as good as Mn–Co but better than Co alone in terms of catalytic activity. It is noted that the catalytic oxidation of
cyclohexane with Mn as a catalyst in Trial 3 gave a total conversion of cyclohexane of 73% and 28.8% of which were oxygenates which contained 15.2% of dimethyl succinate, 19.6% of dimethyl glutarate and 65.2% of dimethyl adipate. Also, the reaction encountered a carbon loss of 71.2%. The main reason for the carbon lost could due to the further oxidation of cyclohexane to volatile products such as carbon monoxide, carbon dioxide and probably to carbonaceous residue, which, unfortunately, cannot be detected by the current analytical protocols.
In order to obtain the best total cyclohexane conversion and the best selectivity towards oxygenates with a minimum carbon lost, the temperature of the reaction was altered from 373 K in Trial 7 to 343 K in Trial 9. It was evident that a good carbon balance
was obtained in Trial 8 where the total cyclohexane conversion was 78% with 74% of the starting cyclohexane converted to oxygenate. Therefore, a carbon balance (selectivity towards oxygenates) of 95% was obtained. It was noted that amongst the 74% cyclohexane conversion to oxygenates, 68% of that was the dimethyl adipate. Thus, there was a 50% conversion of cyclohexane to adipic acid in a single step oxidation, which represented the best result from this present study.
4. Conclusion
To summarize this new preliminary study, we have shown that the combination of Mn(II) and Co(II) is an efficient catalyst for the one-step aerobic oxidation of cyclohexane to adipic acid, displaying a much higher activity than Co(II) and Mn(II) alone. On the other hand, Co–Mn is the best catalyst in term of selectivity towards oxygenates under the conditions studied. Also we observed in this study there is a direct proportional relationship between the cyclohexane conversion and the amount of catalyst initiator "NHPI". However, regarding selectivity towards oxygenates the relationship becomes the opposite. Equally, the same trends were found with respect to the temperature effect. These reflect the major challenge of selective oxidation of organic molecules where higher substrate conversion will associate with lower selectivity due to the problems of ’over-oxidation’ of the products. Bearing in mind that the main goal of "green chemistry" is to achieve both high conversion and high selectivity for cyclohexane with producing fewer harmful products to the environment, thus the present preliminary result showing more
than 50% yield of adipic acid from the single-step aerial oxidation of cyclohexane using NHPI/transition metal ion without using nitric acid represents a promising new direction.

Answer 1

由于从审判3日， 5日和6 ，使用锰钴审判6制作了100 ％环己烷转换，这表明锰钴作为催化剂对一个更好的角度催化活性。锰不如锰，钴，但比公司仅在催化活性。据指出，催化氧化
环己烷锰作为催化剂在审判3了总转化环己烷的73 ％和28.8 ％ ，其中含氧化合物其中载有15.2 ％的二甲基丁二酸， 19.6 ％的二甲基戊二和65.2 ％的二己二酸。此外，遇到一个反应碳损失的71.2 ％ 。主要原因碳丢失可能由于进一步氧化环己烷动荡的产品，如一氧化碳，二氧化碳，可能对碳渣，不幸的是，不能检测到目前的分析议定书。
为了取得最好的总环己烷转化率和选择性的最佳实现氧化物最低碳丢失，温度改变的反应是从373 K的审判7至343 K的审判9 。很明显，一个良好的碳平衡
获得了审判8的总环己烷转化率78 ％与74 ％的转换开始环己烷氧化。因此，碳平衡（选择性对含氧化合物）的95 ％获得。有人指出，其中74 ％环己烷转化为含氧化合物， 68 ％ ，这是二己二酸。因此，有50 ％的转换环己烷合成己二酸在一个单一的步骤氧化，这是最好的结果从本研究。
4 。结论
总结这一新的初步研究，我们已经表明，相结合的锰（ II ）和钴（ II ）是一种有效的催化剂一步有氧氧化环己烷合成己二酸，展示了高得多的活性比钴（ II ）和Mn （二）独立。另一方面，公司锰是最好的催化剂在任期内实现含氧化合物选择性的条件下研究。此外，我们在本研究中观察到有直接的比例关系，环己烷转化率和催化剂用量引发“ NHPI ” 。然而，关于对含氧化合物选择性的关系变得相反。同样，发现了同样的趋势方面的温度效应。这些反映的重大挑战的选择性氧化的有机分子在高基转换将准选择性由于较低的问题， '过氧化'的产品。铭记的主要目标是“绿色化学”是实现高转化率和高选择性的环己烷生产减少有害影响的产品的环境，因此目前的初步结果显示更多
