在60 kt/a环己酮的环己烷液相无催化氧化装置上,探讨了反应温度和气液比对环己烷氧化反应的转化率及选择性的影响.结果表明:控制环己烷氧化反应温度164～168℃,1#～5#反应釜各釜温差3～5℃,气液比44 ～48,氧化反应转化率达5.5％时,反应选择性仍在90％以上；装置连续运行10d,生产稳定.%The effects of reaction temperature and gas to liquid ratio on the conversion rate and selectivity of cyclohexane oxidation were discussed on a 60 kt/a non-catalyst liquid-phase cyclohexane oxidation to cyclohexanone plant. The results showed that the selectivity was still above 90% when the conversion rate of cyclohexane oxidation achieved 5.5% under the conditions as followed; cyclohexane oxidation temperature 164 - 168 ℃ , temperature difference between the reactors 1# -5# within 3 -5 ℃, gas to liquid ratio of 44 -48. The plant can be assured to operate steadily for 10 d.
