|Title:||Ebulliometric Behaviour Of Aqueous Solutions Of Urea|
|Author:||De Azevedo F.G.|
De Oliveira W.A.
|Abstract:||Boiling-temperature elevations for aqueous urea solutions in the molality range 0 to 0.38 mol·kg-1 were measured with a thermistor ebulliometer. Osmotic and activity coefficients were calculated and show behaviour very close to ideality. The boiling-temperature elevations were used to calculate the dimerization constant of urea: (2.6±0.3) × 10-2 kg·mol-1 at 371.5 K and infinite dilution. The results are discussed in terms of urea association through dipole-dipole interactions and also of the "structure-breaking" effect. © 1984.|
