摘　　要：通过冷模实验对环己烷富氧氧化反应器内液相空间危险性进行分析,测试了液相空间气泡危险性。结果表明:环己烷富氧氧化(氧气体积分数大于30.0%)反应时,液相气泡的危险性比空气氧化的危险性大;在空气氧化和富氧氧化(氧气体积分数小于50.4%)工艺条件下,均未观察到气泡经点火后引起反应器体系内压力升高的现象,液相气体内反应均无燃爆危险。The liquid-phase space risk was analyzed and the bubble risk in liquid-phase space was tested for cyclohexane oxygen-enriched oxidation reactor by cold model test. The results showed that the cyclohexane oxygen-enriched oxidation（ oxygen volume fraction above 30.0% ） is more risky than air oxidation in liquid-phase space. No overpressure phenomenon resulting from bubbles after igniting was observed in the reaction system under air oxidation and oxygen-eneriched oxidation（ oxygen volume fraction below 50.4% ） conditions. No deflagration risk was explored for the liquid-phase space.
