Excess viscosities of binary mixtures of chloroform and alcohols

Π-Stacking Signature in NMR Solution Spectra of Thiophene-Based Conjugated Polymers

“…This is still more surprising if we consider that the viscosity of methanol–chloroform mixtures increases with respect to that of the pure solvents at high chloroform molar fractions. 58 Hypothesizing a similar behavior for the deuterated solvents, we interpolated a value of 5.7 × 10 –4 kg m –1 s –1 for the viscosity of the employed solvent mixture (taking as a reference the viscosity of deuterated chloroform reported in ref (59)). Employing the Stokes–Einstein equation for the translational diffusion coefficient, D = kT /(6πη r H ), the diameters of the diffusing particles can be estimated to be around 6.4 and 4.5 nm in chloroform and in methanol–chloroform mixture, respectively.…”

Experimental densities and derived thermodynamic properties of liquid propan-1-ol at temperatures from 298 to 423K and at pressures up to 40MPa

“…It can be seen that the majority of deviations are lower than ±0.1%, the average absolute deviation (AAD) is about 0.06% (see also Table 3). Most of the data by Zúñiga-Moreno and Galicia-Luna [53] show systematic negative deviations, although the deviations are very close [49]; ( ), [56]; ( ), [71]; (×), [58]; (⊗), [64]; ( ), [74]; (♦), [47]; (+), [65]; ( ), [73]; ( ), [61]; ( ), [70]; ( ), [62]; ( ), [33]; ( ), [72]; (♂), [76]; (♀), [32]; ( ), [75]; ( ), [35]; ( ), [36]; ( ), [21]; (--), calculated with correlation by Khasanshin [92]; (----), calculated with correlation by Marczak et al [47].…”

Measurements of the viscosity of alcohols in the temperature range 290?340 K at pressures up to 30 MPa

“…Since some investigators do not adhere to this practice, dis-crepancies are to be expected. For the atmospheric-pressure measurements of the viscosity of the alcohols, an Ubbelohde type of viscometer was used by Rauf et al [13,1 (no calibrant liquid quoted), Crabtree and O'Brien [14] and Paez and Contreras [15] (both calibrated with water), and Phillips and Murphy [16] (calibrated with diethyl ether). Although they all quote uncertainties of about +0.2%, their values deviate from the present measurements up to -3, -1.6, -I.7, and +1.2%, respectively.…”
