摘要：

Vapor pressure data were measured for the following carboxylic acids: propionic, butyric, isobutyric, valeric, isovaleric, hexanoic, and heptanoic acids. The pressure ranged between similar to5 kPa and atmospheric pressure (at sea level), and the corresponding temperatures were between 85 and 180 degreesC, depending on the acid being measured. The data were regressed using both the Antoine and Wagner equations, and the parameters obtained for each equation are presented. The experimental data were also compared to literature data, and the results are discussed.
