and sublimation were derived from the vapor pressure temperature dependencies measured by the transpiration method. Molar enthalpies of the solid state phase transitions were measured by the DSC. Thermodynamic data on alkoxy substituted benzoic acids available in the literature were collected and combined with own experimental results. This data set on alkoxybenzoic acids was evaluated by using quantum-chemical
摘要 使用燃烧量热法测量了 2-、3- 和 4-异丁氧基苯甲酸在温度 T = 298.15 K 下的标准 (p° = 0.1 MPa) 摩尔生成焓。蒸发和升华的标准摩尔焓来自于通过蒸腾法测量的蒸气压温度依赖性。固态相变的摩尔焓通过DSC测量。收集了文献中可用的烷氧基取代苯甲酸的热力学数据,并将其与自己的实验结果相结合。这个关于烷氧基苯甲酸的数据集是通过使用量子化学和基团可加性方法评估的。
