ABSTRACT
Two new analytical methods using UV-spectroscopy and densimetry have been applied for measuring LLE of the following systems at lower temperatures in the region of restricted mutual solubilities: [CnMIM][NTf2] (n = 2,4,6), + n-butanol, + n-pentanol, + water. The data obtained agree very well with results obtained at higher temperatures for the same systems using the synthetic laser scattering method.
