Liquid–liquid
equilibrium data are widely used in many industrial
sectors. For this reason, it is important to know thermodynamics binary
mixture data to better understand molecular interactions between components.
This work reports experimental density (ρ) and speed of sound
(υ) data for 2-hydroxyethanolamine acetate + 1-propanol, 2-hydroxyethanolamine
acetate + 2-propanol, 2-hydroxydiethanolamine acetate + 1-propanol,
and 2-hydroxydiethanolamine acetate + 2-propanol binary mixtures,
over a wide composition range, between 293.15 and 323.15 K, and at
atmospheric pressure (101.3 kPa). For this purpose, a vibrating tube
densitometer was used to perform density and speed of sound experimental
measurements. From these data, important derivative properties have
been calculated, such as isentropic compressibility (κs), apparent molar isentropic compressibility (κø), excess molar volumes (V
m
E), and apparent molar volume (V
Ø).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
