| 摘 要： | 采用GR-3500型氧弹量热计实验测定了顺式-1,2-环己二醇和反式-1,2-环己二醇的标准燃烧焓,分别为-3507.043kJ/mol和-3497.8kJ/mol,并用萘作标准物验证测试仪器,其实验测定值与文献值相对误差为0.053%,同时推算出环己二醇的标准摩尔生成热,分别为568.997kJ/mol(顺式)和578.240kJ/mol(反式)。用NETZSCHDSC204型差示扫描量热仪测定了1,2-环己二醇的定压热容,拟合出环己二醇摩尔定压热容与温度之间的函数关系;同时还测定了1,2-环己二醇的熔点和熔化热,为该产品的新工艺开发、工程设计和工业化生产提供了基础数据。

| Abstract: | The standard combustion enthalpy of 1,2-cyclohexanediol of the differ geometric structure, as trans-1,2-(cyclohexanediol) and cis-1,2-cyclohexanediol, were determined by calorimeter, which were respectively -3497.8 kJ/mol and -3507.043 kJ/mol at 298.15 K(25 ℃), and the standard enthalpy of formation of 1,2-cylcohexanediol was calculated to be 568.997 kJ/mol (cis-) and 578.240 kJ/mol (trans-). The function relationship between heat (capacity) and temperature, the melting point as well as the melting heat, were determined by NETZSCH DSC 204 (Scanning) Calorimeter for 1,2-cyclohexanediol. The basic data were furnished for the exploiting new synthesis method, engineering design and industrialized production on 1,2-cyclohexanediol |
