Thermodynamics of Mixtures Containing a Very Strongly Polar Compound. 10. Liquid–Liquid Equilibria for N,N-Dimethylacetamide + Selected Alkanes

Liquid−liquid equilibrium (LLE) temperatures versus composition for N,Ndimethylacetamide (DMA) + decane, + dodecane, + tetradecane, + 2,2,4-trimethylpentane, + methylcyclohexane, or + cyclooctane mixtures have been measured by means of the critical opalescence method using a laser scattering techniq...
