Abstract: The molar heats of solution of gaseousn-Butane, n-Butene-1 and Butadiene-1,3 in 4 pure dipolar aprotic solvents (dimethylformamide, dimethy sulfoxide, propylene carbonate and N-methy-2-pyrrolidone) and in a protic solvent(methanol) have been calorimetrically determined at 298.15 K and 1 atm(Table 3).
The calorimetric measurements were made by expansive calorimeter, the sensi- tivity was 0.01 cal. The solute molarities were all below 0.04. The measurements of solute content were made by gas chromatography.
The theoriti...
