Exptl. Free Energy Values?

 I am interested in the experimental values
 of free energy of solvation(in water) of the
 following compounds: Methylamine, Ethanol,
 Tetramethylammonium chloride and ammonium chloride.
 If someone can point out some relevant literature I
 would be much obliged.  This is for a comparison
 with my computed 'deltaG' values of transformation
 in water of: Methylamine to methane
 Ethanol to ethane tetramethylammonium chloride
 to ammonium chloride.
 Many Thanks.
