Thermodynamics of amine + ketone mixtures 3. Volumetric, speed of sound data and viscosity at (303.15 and 308.15 K) for the binary mixtures of N,N-dimethylaniline + propiophenone, + p-methylacetophenone, + p-chloroacetophenone

► The curves for the systems of N,N-DMA with all the aromatic ketones were negative over the entire composition at 303.15K &308.15K. ► The deeper minima were observed in the curves of p-chloroacetophenone due to mesomeric effect. ► The curves of VE and ∆η do not obey general rule which as observed in many systems. ► The ultrasonic sound velocity data are the same for the mixtures containing p-methylacetophenone and propiophenone.
