“…As illustrated in figure 7, the agreement between the available viscosity data is quite good, most of the data are represented within 2%. The results from Et-Tahir et al [19] exhibit larger scatter than data of other authors as has been already illustrated by Balogun et al [6] and is in line with what we have seen for other xylene isomers. The three data sets of…”

“…The average absolute deviation is 1.7% with a maximum deviation of -1.9% with most of the data laying below the currently reported values at all four isotherms. Et-Tahir et al [19] also reported the measurements at high pressure by means of the falling body viscometer with a claimed uncertainty of 2%. The deviations cover the range from -0.9% to 3.8% and the magnitude of the deviations is broadly…”

“…The deviation of data of Bridgman 27 display the AAD of 1.5 %, which is in agreement with what we observed for p-xylene. The data of Et-Tahir et al 47 display large scatter with maximum deviation of -4.5 %, while the data of Mamedov et al 34,35 display systematic trends at certain temperatures with maximum deviation of -3.8 %. 22 for the liquid viscosity shows large deviations from the current correlation with a systematic trend extending from -4.6 % to 4.6 % in the temperature range (273 to 403) K. …”

A new correlation for the viscosity of meta-xylene (m-xylene) is presented. The correlation is based upon a body of experimental data that has been critically assessed for internal consistency and for agreement with theory. It is applicable in the temperature range from 273 K to 673 K at pressures up to 200 MPa. The overall uncertainty of the proposed correlation, estimated as the combined expanded uncertainty with a coverage factor of 2, varies from 1 % for the viscosity at atmospheric pressure to 5 % for the highest temperatures and pressures of interest. Tables of the viscosity, generated by the relevant equations, at selected temperatures and pressures, and along the saturation line, are provided.-1 -CONTENTS

High-pressure viscosity of polystyrene (M w ϭ 50,000, M w /M n Յ 1.06) solutions in toluene and in mixtures of toluene ϩ carbon dioxide was measured using a falling cylinder-type viscometer at 320, 340, and 360 K, and up to 35 MPa. Solutions with polystyrene concentrations of 3, 5, and 7 wt % were investigated. Carbon dioxide levels in the range from 0 to 14.7 wt % were evaluated. Viscosity was observed to vary linearly with pressure at the temperatures and polymer concentrations investigated. Viscosity of the polymer solutions decreased as the concentration of carbon dioxide in the mixture was increased. The largest viscosity reduction was observed at the lowest temperature and at the highest concentration of polymer. The viscosity of the solutions was correlated with the solution density for different compositions. It was found that solutions of the same density have different viscosities, depending upon the carbon dioxide concentration in the mixture. The solutions with the higher carbon dioxide content display the lower viscosities at a given density.
