Estimativa por DSC das entalpias de sublimação da etilenouréia e da propilenouréia: algumas correlações empíricas envolvendo amidas e tioamidas Estimative by DSC data of the sublimation enthalpies for ethyleneurea and propyleneurea: some empirical correlations with amides and tioamides
<abstract language="eng">By using DSC data, the enthaplies of sublimation for ethyleneurea and propyleneurea, are calculated as 84 and 89 kJ mol-1 respectively. Using the vaporization enthalpy values for dimethylethyleneurea and dimethylprophyleneurea, as obtained from literature, th...
