| Abstract: | A thermodynamic study was carried out on urea and 12 of its alkyl derivatives by the methods of combustion calorimetry, vapor formation, and differential scanning calorimetry. The numerical data obtained permitted determination of the enthalpy of formation of the above substances under standard conditions and in the gas phase. An additive scheme was proposed for calculating the thermodynamic properties of alkyl substituted urea.Translated from Izvestiya Akademii Nauk SSSR, Seriya Khimicheskaya, No. 4, pp. 750–755, April, 1990. |
