测量了苯甲酸甲酯、乙酸乙酯、正丙酯、异丁酯和正丁基苯甲酸甲酯、乙酯、正丙酯和正丁酯在0.50-30千帕压力范围内的蒸气压。用切比雪夫多项式、米勒方程、弗洛斯特-卡尔瓦尔方程和安托万方程对结果进行了检验。这五种苯甲酸酯的米勒拟合压力的均方根百分比偏差分别为0.30、0.30、0.25、0.16和0.24。用切比雪夫多项式求出了苯甲酸酯的汽化热，平均误差为±0.2kJ/mol。
The vapor pressures of methyl, ethyl, n-propyl, Isobutyl, and n-butyl benzoates were measured over the pressure range of 0.50-30 kPa. The results were examined by fitting with a Chebyshev polynomial and with Miller, Florst-Kalkwarl, and Antoine equations. The percent root mean square deviations of pressures of these five benzoates for the Miller fit were 0.30, 0.30, 0.25, 0.16, and 0.24, respectively. The enthalpies of vaporization of the benzoates were also obtained by using a Chebyshev polynomial with mean errors of±0.2 kJ/mol.
