The isobaric molar heat capacities of ethyl octanoate and ethyl decanoate were determined at T = 294–354 K and p = 0.1–24 MPa. The measurements were conducted by a flow calorimeter. The measured results were in good agreements with several available experimental data at atmosphere pressure and the calculated results at high pressure in literatures. Furthermore, a fitting equation was presented to calculate the C_p of ethyl octanoate and ethyl decanoate. The maximum absolute relative deviations between experimental results and calculated data are lower than 0.4%.

压力高达24 MPa的辛酸乙酯和癸酸乙酯的等压摩尔热容

辛酸乙酯和癸酸乙酯的等压摩尔热容在T = 294–354 K和p = 0.1–24 MPa时测定。通过流量热计进行测量。测量结果与大气压力下的一些可用实验数据和高压下的计算结果与文献中的数据吻合良好。此外，提出了拟合方程来计算辛酸乙酯和癸酸乙酯的C _p。实验结果和计算数据之间的最大绝对相对偏差小于0.4％。
