英文摘要the low-temperature heat capacity of 2-thiopheneacetic acid was measured in the temperature range from 78 to 343 k with a high precision automated adiabatic calorimeter. no phase transition or other thermal anomaly was observed in the temperature ranges of 78 similar to 314 and 337 similar to 343 k, in which the molar heat capacities were fitted to two polynomials by means of the least square fitting. a solid-liquid phase transition was observed in the temperature range of 314 similar to 337 k. the melting point, molar enthalpy and entropy of fusion, and molar purity of this compound were determined to be 335.745 k, 16.260 kj.mol(-1), 48.415 j.k(-1).mol(-1) and 98.56%, respectively. the thermodynamic functions of 2-thiopheneacetic acid relative to the reference temperature 298.15 k were derived based on the heat capacity data in the temperature range of 80 similar to 340 k.
