Abstract
The thermal conductivity of methanol vapor was measured in a modified thick hot-wire cell between 307 and 345 K at pressures ranging from approximately 50 torr up to a maximum of 1 atm. Analysis of the experimental data indicates that a tetrameric species is the principal source of the observed enhancement of the thermal conductivity of the vapor due to association reactions. Equilibrium constants for the reaction 4CH3OH? (CH3OH)4 were determined from the thermal conductivity data. The enthalpy of formation of the methanol tetramer is −23.73 kcal/mole and the entropy of formation is −80.92 cal/mole K.
