Excess Volumes and Viscosities of Binary Mixtures of Aliphatic Alcohols (C₁−C₄) with Nitromethane

Abstract

Densities and viscosities were measured for the binary mixtures of methanol, ethanol, propan-1-ol, propan-2-ol, butan-2-ol, and 2-methyl-propan-2-ol with nitromethane at temperatures from 293.15 K to 313.15 K and atmospheric pressure. Densities were determined using a vibrating-tube densimeter. Viscosities were measured with an automatic Ubbelohde capillary viscometer. The estimated uncertainties are less than ±0.0001 g·cm-3 for density and ±0.7% for viscosity. Excess volumes and viscosity deviations as a function of mole fraction average were derived, and the computed results were fitted to the Redlich−Kister equation. Furthermore, McAllister's three-body-interaction model is used to correlate the binary kinematic viscosities.

Fluorescence enhancement of warfarin induced by interaction with β‐cyclodextrin

“…The dynamic viscosity of water is 1.30 cP and 0.406 cP for 10 C and 70 C, respectively, 38 and the dynamic viscosity of methanol is 0.581 cP and 0.398 cP for 20 C and 50 C, respectively. 39,40 These findings, therefore, suggest that the observed temperature dependence of the fluorescence quantum yield of warfarin is predominantly induced by changes in the viscosity of the media resultant from thermal alterations.…”

Densities and viscosities of binary mixtures of {dimethylsulfoxide+aliphatic lower alkanols (C1–C3)} at temperatures from T=303.15K to T=323.15K

“…For every measurement, a thermostatic water bath (Techne, TE-8A) controlled to ±0.01 K was used. On the basis of the comparison of the measured density and viscosity with the literature [5,7,9,10,12,[15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30] data, presented in table 1, and the observation of no significant second peaks in the gas chromatograms, the pure liquids used in this study are at least 99.9% pure.…”
