摘　　要：临界参数一般很难通过实验方法获得,因此本文分别采用Lydersen法、Joback法、MXXC法估算了3-甲基-3-丁烯-1-醇、异佛尔酮、丁酮醇、甲基庚烯酮四种物质的临界条件。根据估算结果计算平均值,这四种物质的临界压力分别为3.95 MPa、3.18 MPa、4.69 MPa、2.8 MPa,相对标准偏差在8%以内;而临界温度分别为574.9 K、706.6 K、616.3 K、672.8 K,相对标准偏差在1.5%以内。通过理论计算得到的这些临界参数数据将为工业设计及生产提供理论依据。Lydersen method,Joback method and MXXC method were used in estimation of critical temperature and pressure of the substance as follows:3-methyl-3-buten-1-ol,isophorone,4-hydro-2-butanon and methylheptenone.The critical pressures of these four substances were 3.95 MPa,3.18 MPa,4.69 MP and 2.8 MPa,and the relative standard deviation was within 8%.While the critical pressures of these four substances were 574.9 K,706.6 K,616.3 K and 672.8 K,and the relative standard deviation was within 1.5%.These basic data can be used in industry design and production.
