EXCESS VOLUMES OF 1,2-DIBROMOETHANE PLUS 1-PROPANOL, PLUS 1-BUTANOL, OR PLUS 1-PENTANOL FROM 293.15 TO 333.15-K

Abstract

Excess molar volumes V(E) of 1,2-dibromoethane with 1-propanol, 1-butanol, and 1-pentanol have been measured at five temperatures, from 293.15 to 333.15 K. NMR shifts have also been reported for the mixtures of 1,2-dibromoethane with 1-butanol at 303.15 K. V(E) is positive in all the mixtures studied over the whole range of compositions at all temperatures and increases in the order 1-pentanol > 1-butanol > 1-propanol. The temperature coefficient of V(E) is positive. The positive excess molar volumes have been ascribed to deassociation of self-associated alcohol aggregates.
