Determination of thermodynamic properties for protonation equilibrium between isomeric cresols and N,N-dimethylaniline in n-hexane medium

Experimental and Predicted Vapor–Liquid Equilibrium for Diisopropanolamine with m-Cresol and 2,6-Dimethylphenol at 20.0 kPa

“…This phenomenon was easy to analyze because the secondary amine group in DIPA had a strong interaction (i.e., hydrogen bond formation) with the group of hydroxyls in MC. 28,29 Similar behavior was found in the system of MC + quinoline. a Standard uncertainties u are u(T) = 0.05 K, u(p) = 0.07 kPa, and u(x 1 ) = u(y 1 ) = 0.005.…”

“…This condition indicated that the system is a negative deviation solution compared with the ideal system. This phenomenon was easy to analyze because the secondary amine group in DIPA had a strong interaction (i.e., hydrogen bond formation) with the group of hydroxyls in MC. , Similar behavior was found in the system of MC + quinoline. Quinoline is a polar compound capable of hydrogen bonding through the nitrogen atom.…”

Ultrasonic and spectral studies on charge transfer complexes of anisole and certain aromatic amines

“…Similarly, in the formation of 1:1 complex between p-benzoquinone and hydroquinone, hydrogen bond exists between the donor and acceptor components [15]. Recently, we determined the equilibrium constants for the protonation of N,N-dimethylaniline with three isomeric cresols by ultrasonic method and correlated the hydrogen bond stabilized protonated species with the molecular properties of proton donors [16]. In this paper, the results obtained in the study of molecular interaction between anisole with two amines namely aniline and N-methylaniline in n-hexane medium are presented.…”
