Experimental determination and modeling of densities and refractive indices of the binary systems alcohol + dicyclohexylamine at T = (288.15-323.15) K

► Densities and refractive indices of alcohols + dicyclohexilamine were determined. ► Large negative VmE values are consequence of strong intermolecular interactions. ► For the correlation of VmE data three parameters Twu et al. model is recommended. ► Newton and Oster mixing rules are suggested for refractive indices calculations.
