摘　　要：在363～423 K条件下,采用静态法测定了质量分数为55%的乙醇-水复合溶剂(以下简称试样1)及质量分数为25%的对氨基苯酚-乙醇/水复合溶剂体系(以下简称试样2)的饱和蒸汽压。用Antoine方程对实验数据进行了非线性回归。结果表明,试样1的Antoine方程常数项A,B,C依次为16.042,-3 305.400,-64.496,相关系数为0.999 97。试样2的上述各值依次为10.525,-605.260,-269.020,0.999 94。试样1的计算值与实验值的平均偏差为0.60%,最大偏差为1.27%;试样2的分别为0.95%,2.30%。Saturated vapor pressures of ethanol-water mixed solvent（mass fraction of 55%,sample 1）and p-aminophenol-ethanol/water system（mass fraction of 25%,sample 2）were measured by static method at 363-423K,respectively.The non-linear regression of experimental data was conduced by Antoine equation.The results showed that constant terms A,B,C of Antoine equation for sample 1 in turn were 16.042,-3305.400,-64.496,correlation coefficient was 0.999 97.The above values of sample 2 in turn were 10.525,-605.260,-269.020,0.999 94.The average deviation of sample 1 between the calculated value and the experimental data was less than 0.60% and the maximum deviation was 1.27%,those of sample 2 were 0.95%,2.30%,respectively.
