✦ Synopsis


Experimental data concerning the latent heat of vaporization of cyrlohexane are not available over a wide range of temperatures. Because information concerning the enthalpy change upon vaporization has many industrial applications, experimental investigation was de&able. Direct calorimetric measurements of the latent heat of vaporization of cycZohexane are reported for temperatures between 100' and 310"". The experimental data were obtained under substantially isobaric-isothermal conditions. The results are presented in graphical and tabular form with values based upon volumetric data and limited measurements near room temperature. RBsum&Les don&es exp&imentales concemant la chaleur latente de vapourisation du cyclohexane ne sont pas utilisables dans un grand intervalle de Gmperatures. line recherche expbrimentale pa&t s'imposer du fait que lea don&es concernant la variation d'enthalpie au deli de la vaporisation sont utilides dans l'industrie. Des mesures calorim6triques directes de la chaleur latente de vaporisation du cyclohexane ont Btr5 faites pour des temperatures comprises entre 100" et 310 OF. L'expCrimentation a &tB conduite dans des conditions essentiellement isobares ct isothermes. Les r&ultats sont don& sous forme de tableaux et de graphiques ; les valeurs sont etablics B partir des don&es volumCtriques et les mesures sont effectuPes B la tempdrature ambiante. Zusammenfassung-Experimentelle Daten iiber die latente Verdampfungswiirme von Cyclohexan stehen fiir einen grossen Temperaturbereich nicht zur Verfiigung. Eine experimentelle Untersuchung schien wiinschenswert, da die Enthalpieiinderung bei der Verdampfung bei vielen industriellen Anwdenungen ben6tigt wird. Direkte kalorische Messungen der latenten Verdampfungswgrme von Cyclohexan werden fiir Temperaturen zwischen 100 und 300 "F mitgeteilt. Die Daten wurden unter isobaren-isothermen Bedingungen erhalten. Die Ergebnisse werden in graphischer Form und in Tabellen angegeben, wobei die Werte auf vohnnetrischen Daten und einigen Messungen nahe der B.aumtemper@r beruhen.

## Abstract Simple relations are given for the variation of the latent heat of vaporization of non‐associated liquids with the absolute temperature and the density. These relations are applicable over ranges of 50Β° and 100Β°, respectively, above the boiling point of the liquid. It is shown that the
