Calculating the Enthalpy of Vaporization of Ethanol, -Heptane, Isooctane, and a Binary Mixture of Isooctane + -Heptane from Their Vapor Pressure Data.

ConspectusA key physical property of volatile liquids is vapor pressure (VP). Volatile organic compounds (VOCs) are a classification of compounds directly associated with low boiling points, high rates of evaporation, and high flammability. The majority of chemists and chemical engineers were directly exposed to the odor of simple ethers, acetone, and toluene in the air while taking an organic chemistry laboratory course as an undergraduate student.
