Isobaric heat capacities of R1234ze(E) were investigated by using a modified flow calorimeter covering a temperature range from 313 to 393 K and pressures up to 10 MPa. The uncertainties in measurement of the heat capacity were estimated to be less than 0.01 at temperatures below 373 K, rising to 0.02 in the near critical region (373 and 393 K). An empirical equation was developed for correlation on the basis of the experimental data. In addition, a comparison was made between the present data and literature values.

在313至393 K的温度和最高10 MPa的压力下R1234ze(E)的热容量。

通过使用改良的量热计,研究了R1234ze(E)的等压热容,该量热计的温度范围为313至393 K,压力最高为10 MPa。在低于373 K的温度下,热容测量的不确定性估计小于0.01,在近临界区域(373和393 K)上升至0.02。在实验数据的基础上,建立了一个用于相关性的经验方程。另外,在当前数据和文献值之间进行了比较。
