AB 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 criticalopalescence method using a laser scattering technique. All the systems show an upper criticalsolution temperature (UCST). In the case of n-alkane mixtures, UCST increases almostlinearly with the chain length of the n-alkane. Moreover, these solutions show higher UCSTvalues than those with isomeric cyclic alkanes. Branching leads to a strong decrease of UCST.The symmetry of the LLE curves depends on the size and shape of the alkane. DISQUACcorrectly represents the coordinates of the critical points using interaction parameters availablein the literature.
