Density, ultrasonic velocity, viscosity and their excess parameters of the binary mixtures of N,N-dimethylaniline+1-alkanols (C3-C5), +2-alkanols (C3-C4), +2-methyl-1-propanol, +2-methyl-2-propanol at 303.15K

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

“…prepared by weighing appropriate amounts of pure liquids and mixed in airtight stoppered bottles to minimize evaporation losses. The values of ultrasonic velocity and density of pure components required to calculate the acoustical properties and formation constant of the complex are available in literature [18][19][20][21][22][23] and those values were used in our calculations. The density, ρ of the ternary systems was determined by using a 10 ml specific gravity bottle.…”

Intermolecular interactions in mixtures of ethyl formate with methanol, ethanol, and 1-propanol on density, viscosity, and ultrasonic data

“…Alcohols are highly self associated through hydrogen bonding. They can also be associ ated with any other group having some degree of polar attraction [6][7][8]. Present work is an attempt to eluci date molecular interaction between binary mixtures of ethyl formate with methanol, ethanol, and 1 propanol at 303 K by using ultrasonic technique.…”

Viscosity and Speed of Sound Studies of Binary Liquid Mixtures of Formamide with N,N-Dimethylaniline at Different Temperatures

“…The validity of these theories was checked by applying chi-square test (χ) for goodness of fit and by calculating the average percentage error (APE) [2,6]. Further, the mixture viscosities were correlated using Hind, Grunberg and Nissan, Katti and Chawdhry, Tamura & Kurata, equations to test their relative applicability with standard deviation (σ) [2,6] for the binary mixture of formamide with N,Ndimethylaniline at different mole fractions [9][10][11]. The results are explained and discussed in terms of molecular interactions present in the investigated systems.…”
