原料过氧化氢异丙苯(CHP)中的Na+存在于油相中的微量水中,水洗30 min后油水分层达到平衡. 当CHP和水体积比为5时,Na+离子脱除率接近100%. 催化剂固含率小于0.8%时,反应速率与固含率近似呈线性关系,固含率大于0.8%时,传质扩散过程是反应的控制步骤,固含率的增加对反应速率没有显著影响. 同样,在60~90℃范围内,反应温度对总反应速率的影响并不显著,这也是因为传质扩散是控制步骤. 另外,反应速率随原料中水含量的增加而下降,因此,必须控制原料中的水含量. 采用气液固三相流化床反应器,CHP进料空速可达50 h-1,产物中CHP含量小于0.1%.
Na + in the raw material cumene hydroperoxide (CHP) is present in the trace water in the oil phase, and the oil-water layer equilibrates after 30 min of water washing.When the volume ratio of CHP to water is 5, the removal rate of Na + ions is close to 100% When the solid content of the catalyst is less than 0.8%, the reaction rate is approximately linear with the solid content, and when the solid content is more than 0.8%, the mass diffusion process is the control step of the reaction, and the increase of solid content has no significant effect on the reaction rate Similarly, the effect of reaction temperature on the overall reaction rate is not significant at 60-90 ° C because of mass transfer diffusion, which is a control step, and that the reaction rate decreases with increasing water content in the feedstock Control the water content in the raw material.Using the gas-liquid solid three-phase fluidized bed reactor, CHP feed space velocity can reach 50 h-1, the CHP content in the product is less than 0.1%.
