摘　　要：采用连续精馏侧线分离技术,从混合二异丙苯中分离间二异丙苯,考察了进料量、回流比、操作压力等因素对间二异丙苯质量分数的影响,并确定了适宜的工艺控制参数。研究分析结果表明,通过连续稳定实验,当进料量为0.6mL/min、操作压力为-0.095MPa、回流比为100∶1(质量比)、塔顶采出和侧线采出的质量比为1∶10时,间二异丙苯产品质量分数稳定在98.5%以上,邻二异丙苯质量分数小于2%,间二异丙苯收率可以达到78.03%,达到工业品技术规格,为工业化实施提供了技术支持。Studied the pilot test of separation of m-diisopropylbenzene(m-DIPB)from mixed diisopropylbenzene.The effects of the inlet amount,the reflux ratio,the pressure and other factors on the content of m-DIPB were investigated,and the appropriate process control parameters were determined.Studied result showed that when the inlet amount is 0.6 mL/min,the pressure is-0.095 MPa,the reflux ratio is 100∶1,the recovery ratio of top production and side line production is 1∶10,the purity of more than 98.5% of m-DIPB product can be obtained,the content of o-diisopropylbenzene is less than2%,the yield of m-DIPB is 78.03%.The product can meet the requirements of the factory on purity of m-DIPB,so we provide theoretical support for the later industrialization.
