Density Measurements of (0.99 Methane + 0.01 Butane) and (0.98 Methane + 0.02 Isopentane) over the Temperature Range from (100 to 160) K at Pressures up to 10.8 MPaCryogenic stateDensity measurementLiquefied binary mixturesMagnetic-suspension coupling...
a density functional teory study of the hydride transfer between 1-adamantyl cation and isopentane has been performed at the pbe1pbe/6-31g(d,p) theoretical level. the results indicate that a carbonium ion is involved as intermediate and is more stable than the van der waals complexes between...

9. The blowing agent blend of claim 1, wherein the polyolefin foam has a density of less than 3 lb/ft3. 10. A polyolefin foam structure prepared by the process comprising: melting a thermoplastic polyolefin polymer, dissolving an effective amount of a blowing agent blend in the polyolefin po...
THERMAL CONDUCTIVITYThis paper reports the results of new, absolute measurements of thermal conductivity of isopentane in the temperature range 307–335 K at pressures up to 0.4 GPa. The experimental data have an estimated uncertainty of ±0.3%. The density dependence of the thermal conductivity ...
In the region above 100 MPa atT= 280 K and 440 K, the uncertainty in the density measurement increased from 0.11% to 0.14% and 0.22%, respectively. TwelvePρTmeasurements were carried out at temperatures and pressures reported in the literature for comparison. Additionally, the results of the...
While the hydrocerol and isopentane are considered to function as the nucleating agent which determines the cell-population density and as the blowing agent to control the volume expansion ratio respectively, both agents affected the cell-population density. In addition, synergistic effects of these ...
The density of acid sites on the top surface of catalysts determined by benzonitrile adsorption proved the average number of H4SiW12O40 layers on SiO2 to be 2.2, 2.6 and 4.0 at 10, 20 and 40 wt.% acid loading, respectively. NH3 temperature programmed desorption showed that the acid ...
