ABSTRACT
This work presents density and viscosity values for (1,3-dimethylurea + water) from (283.15 to 333.15) K for density and (288.15 to 333.15) K for viscosity at molalities up to 23.154 for both measurements. All measurements have been performed at atmospheric pressure. We have used a vibrating tube densimeter for the density measurements while we have used four different Cannon-Fenske viscosimeters for the viscosity measurements. We have calculated dynamic viscosities using the experimental densities.
