中文摘要：

为醋酸 + 秒丁基醋酸盐和水 + 醋酸 + 秒丁基醋酸盐系统的等压的蒸汽液体平衡(VLE ) 数据用一种修改罗斯类型在 101.3 kPa 被决定。醋酸的协会引起的蒸汽阶段的 nonideality 被化学理论和 Hayden-O'Connell 方法改正。热力学的一致性为二进制 VLE 数据被测试。试验性的数据成功地被相关与非随机二个液体(NRTL ) 模型。第三的系统的根吝啬的方形的偏差(RMSD ) 是 0.0038。在 329 ～ 385 K 的秒丁基醋酸盐的浸透蒸汽压力借助于二个连接平衡房间被测量。水和秒丁基醋酸盐的蒸汽压力与 Antoine 方程被相关。二进制相互作用参数和第三的 VLE 数据从这个工作被获得。

英文摘要：

Isobaric vapor-liquid equilibrium（VLE） data for acetic acid ＋ sec-butyl acetate and water ＋ acetic acid ＋ sec-butyl acetate systems were determined at 101.3 kPa using a modified Rose type. The nonideality of the vapor phase caused by the association of the acetic acid was corrected by the chemical theory and Hayden-O＇Connell method. Thermodynamic consistency was tested for the binary VLE data. The experimental data were correlated successfully with the Non-Random Two Liquids （NRTL） model. The Root Mean Square Deviation （RMSD） of the ternary system was 0.0038. The saturation vapor pressure of sec-butyl acetate at 329 to 385 K was measured by means of two connected equilibrium cells. The vapor pressures of water and sec-butyl acetate were correlated with the Antoine equation. The binary interaction parameters and the ternary VLE data were obtained from this work.
