Effect of halogen substitution on the enthalpies of solvation and hydrogen bonding of organic solutes in chlorobenzene and 1,2-dichlorobenzene derived using multi-parameter correlations
Enthalpies of solution at infinite dilution at 298 K, DeltasolnHA/Solvent, have been measured by isothermal solution calorimetry for 43 and 72 organic solutes dissolved in chlorobenzene and 1,2-dichlorobenzene, respectively. The measured DeltasolnHA/Solvent data, along with published DeltasolnHA/Solvent values taken from the published literature for solutes dissolved in both chlorobenzene solvents, were converted to enthalpies of solvation, DeltasolvHA/Solvent, using standard thermodynamic equations. Abraham model correlations were developed from the experimental DeltasolvHA/Solvent data. The best derived correlations describe the experimental gas-to-chlorobenzene and gas-to-1,2-dichlorobenzene enthalpies of solvation to within standard deviations of 1.5 kJ mol-1 and 1.9 kJ mol-1, respectively. Enthalpies of X-H?pi (X – O, N, and C) hydrogen bond formation of proton donor solutes (alcohols, amines, chlorinated hydrocarbons, etc.) with chlorobenzene and 1,2-dichlorobenzene were calculated based on the Abraham solvation equation. Obtained values are in good agreement with the results determined using conventional methods.
A reaction mechanism is the microscopic path by which reactants are transformed into products. Each step is an elementary reaction. 108-47-4, In my other articles, you can also check out more blogs about 108-47-4
