Abstract Measurements leading to the calculation of the ideal-gas thermodynamic properties for 4-methylphenanthrene are reported. Thermochemical and thermophysical properties were determined by adiabatic heat-capacity calorimetry, combustion calorimetry, comparative ebulliometry, and inclined-piston manometry. Results were used to calculate entropies, enthalpies, and Gibbs energies of formation for
摘要 报告了导致计算 4-甲基菲的理想气体热力学性质的测量结果。热化学和热物理性质由绝热热容量热法、燃烧量热法、比较沸腾法和倾斜活塞测压法确定。结果用于计算理想气体状态在选定温度至 500 K 时的熵、焓和吉布斯形成能。使用涉及对一系列甲基取代芳族分子进行比较的组贡献方法来证明理想气体状态的一致性- 气体熵和生成焓为 4-甲基菲确定,相关化合物的文献值。结果显示与使用 nmr 确定的文献中的甲基旋转障碍一致
