Calorimetric Behaviour of Primary Bromobutanes with Isomeric Butanols

Surface Behavior of the 1-Bromobutane with Isomeric Butanol Mixtures

Surface tensions of the 1-bromobutane with isomeric butanol mixtures were measured in the temperature range 283.15 K (or 298.15 K for 2-methyl-2-propanol) to 313.15 K with a drop volume tensiometer, and the corresponding surface tension deviations were calculated. Using this information together with bulk thermodynamic properties a thermodynamic study on surface formation was presented. This study includes the calculation of excess surface compositions and excess properties of surface formation.

Thermodynamic Properties of Isomeric Butanols with 2-Bromobutane

Excess volumes and excess enthalpies for mixtures of isomeric butanols with 2-bromobutane were determined at the temperatures of 298.15 K and 313.15 K. Excess volumes are positive over the whole composition range except for the mixture 1-butanol with 2-bromobutane at 298.15 K in which
