“…4 we present the proposed uncertainty of the data in the different temperature intervals, consistent with Table 2. A single point of Fröba and Leipertz 19 seems to corroborate the tendency of the data of Assael et al, 18 but with a relative deviation of Ϫ1%.

Viscosity is an important transport property for the optimum design of a chemical process plant and for the development of molecular theories of the liquid state. A large amount of experimental viscosity data has been produced for all types of liquids, from alternative refrigerants to molten salts and molten metals. The accuracy of these data is related to the operating conditions of the instrument and, for this purpose as well as for the calibration of relative instruments, standard reference data for viscosity are necessary over a wide range of temperatures. New experimental data on the viscosity of liquid toluene along the saturation line have been obtained recently, mostly at low temperatures. The quality of the data is such that recommended values can be proposed with uncertainties of 0.5% ͑95% confidence level͒ for 260 KрTр370 K and 2% for 210 KрT Ͻ260 K and 370 KϽTр400 K. A discussion about the uncertainties in the measurements and about the purity of the samples is made. The proposed value for the viscosity of liquid toluene at 298.15 K and 0.1 MPa is ϭ554.2Ϯ3.3 Pa s.

“…Under these conditions, the viscosity of toluene ranges from 0.66 to 0.42 cP. [49] The latter control experiments confirm that the large changes in fluorescence quantum yield observed for 1c in 1-octanol as a function of temperature (Fig. 7b) are due mainly to viscosity change in that solvent.…”

The synthesis, characterization, and photophysical properties of a series of supramolecular triads consisting of a tin(IV) porphyrin with axial ligands of ortho‐, meta‐, and para‐hydroxyphenyl naphthalenediimides are presented. For the meta‐ and para‐hydroxyphenyl derivatives, efficient and solvent‐viscosity‐dependent quenching of porphyrin fluorescence is observed. Experimental and theoretical studies demonstrate that, in these compounds, photoinduced electron transfer from the phenolate to the porphyrin is modulated by large amplitude rotational motions of the naphthalenediimide. These compounds are novel examples of fluorescent molecular rotors, and their potential use as environmental probes of local viscosity and temperature are discussed.

“…We find essentially no difference between the densities and viscosities of the two Merck grades over the temperature and pressure range analyzed in this work. The reported and existent data could be used to propose a correlation of the full viscosity surface of DIDP that could be used as standard reference formulation to calibrate or to verify other viscometers that operate at high pressures, using a scheme similar to those considered in 2001, under the auspices of the Subcommittee of Transport Properties of the IUPAC, when Assael et al [44] have recommended a correlation for the viscosity of toluene, using the hard-sphere scheme, over a wide range of temperatures and pressures, considering seventeen sets of measurements performed during two decades, over quite different conditions of pressure and temperature.…”
