Excess volumes, partial molar and adiabatic compressibilities of binary mixtures of n-alcohols with monoethanolamine

Abstract

Speed of sound and densities of solution mixtures of four aliphatic alcohols with monoethanolamine were measured over a full range of composition. The density measurements were carried out from 298 to 358 K. Results of these measurements were used to calculate adiabatic compressibilities, excess adiabatic compressibilities, excess volumes and partial molar quantities. From the analysis of the results, the nature of interaction between the aliphatic alcohols and monoethanolamine is deduced.

Keywords:

• aliphatic alcohols
