Título: | Enthalpy of sublimation/vaporization of trans-cyclohexyl-1,4-diamine and cis-cyclohexyl-1,2-diamine | Autor: | Tomé, Luciana I. N. Rosado, Mário T. S. Nunes, Sandra C. C. Maria, Teresa M. R. Canotilho, João Eusébio, M. Ermelinda S. |
Palavras-chave: | trans-Cyclohexyl-1,4-diamine; cis-Cyclohexyl-1,2-diamine; Sublimation/vaporization; Cyclohexyldiamines | Data: | 2007 | Citação: | The Journal of Chemical Thermodynamics. 39:10 (2007) 1354-1356 | Resumo: | The molar enthalpy of sublimation, , of trans-cyclohexyl-1,4-diamine and the molar enthalpy of vaporization, , of cis-cyclohexyl-1,2-diamine, at the temperature 298.15 K, were determined by calorimetry. was obtained for the trans-isomer and for the cis form. The molar enthalpy of fusion of the first compound, at T = 342.1 K, was determined by differential scanning calorimetry. The molar enthalpy of vaporization of the 1,4-isomer was estimated by combining the value of the enthalpy of sublimation with that of the enthalpy of fusion. | URI: | https://hdl.handle.net/10316/5035 | Direitos: | openAccess |
