The enthalpies of solution of H 2 O and D 2 O in tetrahydrofuran (THF), 1,4-dioxane (DO) and acetone (AC) were measured calorimetrically at 298.15K. Standard (at the infinite dilution) enthalpies of solution, along with D 2 O–H 2 O solute isotope effects on the quantity in question, were calculated. The enthalpies of the solute dissolution were found to be positive...
The enthalpies of solution of 2,4,6,8-tetramethyl-2,4,6,8-tetraazabicyclo[3.3.0]octane-3,7-dione or tetramethyl-bis-urea (the drug Mebicarum) in formamide, N-methylformamide, N,N-dimethylformamide, N,N-dimethylacetamide, N,N,N′,N′-tetramethylurea, and acetone were measured at 298.15K. Standard enthalpies of solution and transfer from one solvent to another were computed. The enthalpies of solution...
