考察了TS-1催化异丙醇部分氧化制H2 O2和环己酮直接氨氧化制H2 O2的工艺集成的可能性。异丙醇部分氧化实验结果表明，在110 °C，10 atm，2 h条件下，H2 O2的产率约为7.5%，分馏后得到典型组成为25.2wt.-%的H2 O2溶液H2 O2，10.3重量%异丙醇，0.29重量%丙酮，0.45重量%磷酸和0.43wt. %乙酸。就环己酮的转化率和环己酮肟的选择性而言，这些杂质的存在达到上述水平不会明显影响环己酮的氨肟化。结果表明，异丙醇部分氧化制H2 O2工艺和环己酮氨肟化工艺可以集成。
The possibility of the integration of the processes of H 2 O 2 production through isopropanol partial oxidation and the direct ammoximation of cyclohexanone with H 2 O 2 and NH 3 catalyzed by TS-1 was investigated. The results of isopropanol partial oxidation showed that around 7.5 % yield of H 2 O 2 was obtained at 110 °C, 10 atm, 2 h, and after fractionation, a H 2 O 2 solution with the typical composition 25.2 wt.-% H 2 O 2 , 10.3 wt.-% isopropanol, 0.29 wt.-% acetone, 0.45 wt.-% phosphoric acid and 0.43 wt.- % acetic acid was obtained. The presence of these impurities up to the above levels did not appreciably influence the ammoximation of cyclohexanone in terms of the conversion of cyclohexanone and the selectivity to cyclohexanone oxime. The results indicate that the processes of H 2 O 2 production through isopropanol partial oxidation and the ammoximation of cyclohexanone can be integrated.
