Thermochemical properties of mono- and di-cyano-aromatic compounds at 298.15 K

Apparatus for determination of vapor pressure by using the transpiration method was developed. The experimental setup was tested by measuring the vapor pressure of pure naphthalene. Vapor pressures for 1- and 2-cyano-naphthalenes were measured by using the newly elaborated transpiration setup. Experimental and calculated values of sublimation enthalpies are in good agreements with the most reliable available literature data. Sublimation enthalpy of 9-cyano-anthracene was obtained by solution calorimetry for the first time.
