- Abstract
The crystal structure of ethylenediamine dilauroleate was determined by X-ray crystallography. A thermochemical cycle was designed in accordance with Hess law. The enthalpy change of the synthesis reaction of ethylenediamine dilauroleate was determined to be $$ \Updelta_{{\text{r}}} H_{{\text{m}}}^{\Uptheta } $$ = −(49.07 ± 0.11) kJ mol by an isoperibol solution-reaction calorimeter. The standard molar enthalpy of formation of the title compound was calculated to be $$ \Updelta_{\text{f}} H_{\text{m}}^{\Uptheta } $$ = −(38.78 ± 0.43) kJ mol by the designed thermochemical cycle, the enthalpies of dissolution and other auxiliary thermodynamic quantities.
