Densities and excess molar volumes of alcohol + cyclohexylamine mixtures

Abstract

Densities of binary mixtures of 1-propanol, or 2-butanol, or 1-pentanol + cyclohexylamine were measured at temperatures from 288.15 to 313.15 K and atmospheric pressure, while the densities for the system 2-methyl-2-propanol + cyclohexylamine were measured at temperatures from 303.15 to 323.15 K and atmospheric pressure. All measurements were performed using an Anton Paar DMA 5000 digital vibrating-tube densimeter. From the experimental densities, the excess molar volumes, VE, were calculated.

Gustine binarnih smeša (1-propanol ili 2-butanol ili 1-pentanol + cikloheksilamin) su merene u temperaturnom intervalu 288,15-313,15 K i na atmosferskom pritisku, a gustine sistema 2-metil-2-propanol + cikloheksilamin su merene u temperaturnom intervalu 303,15-323,15 K i na atmosferskom pritisku. Sva merenja su izvršena na Anton Paar DMA 5000 digitalnom gustinomeru. Iz eksperimentalnih vrednosti gustina izračunate su dopunske molarne zapremine navedenih smeša.
