00925njm 22002777a 4500 dc Alonso Tristán, Cristina author González López, Juan Antonio author García de la Fuente, Isaías author Cobos, José Carlos . author 2013-08 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 technique. All the systems show an upper critical solution temperature (UCST). In the case of n-alkane mixtures, UCST increases almost linearly with the chain length of the n-alkane. Moreover, these solutions show higher UCST values 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. DISQUAC correctly represents the coordinates of the critical points using interaction parameters available in the literature. 0021-9568 http://hdl.handle.net/10259/4700 10.1021/je400487e Thermodynamics of Mixtures Containing a Very Strongly Polar Compound. 10.
