The apparent molal volumes (φ<SUB>v</SUB>) at 25°C have been measured for the following urea derivatives in aqueous alkali chloride solutions (from density measurements) using a digital densimeter: urea, methylurea, ethylurea, 1,1-dimethylurea, 1,3-dimethylurea, 1,1-diethylurea, and 1,3-diethylurea. The limiting values (φ<SUB>v</SUB><SUP>°</SUP>) were obtained by a linear extrapolation using the least-squares method. A notable feature of the transfer volumes found in this study was that hydrophobic urea derivatives, such as dimethylureas and diethylureas, had negative values for transfer from water to lithium chloride solutions. For the remainder, however, all transfer volumes were positive.
