WebDec 1, 2024 · The mobility of the polymer chains depends on the distance from the substrate. The results elucidated that the interfacial layer with a thickness of approximately 1 nm did not swell at all with toluene vapor, which is a solvent for PVAc. Meanwhile, the surface layer excessively swells with toluene vapor compared to the bulk. WebA system is described for the pyrolysis of deuterated and normal toluene using hydrogen as a carrier gas, which produces a simplification in the results. With hydrogen or deuterium as the carrier gas, the quartz tube furnace remains clean, and the only isolable products of the pyrolysis are benzene and methane in approximately equal amounts.
WebMar 1, 2024 · Contrast matching compositions of H 2 O, D 2 O and toluene, deuterated toluene were used to probe open and closed pores of these three shale samples. Results show that although the mean pore radius was approximately the same for all three samples, the fractal dimension of the quartz-rich sample was higher than for the clay-rich and … WebSorption partition coefficients between water and organic carbon (Koc) for deuterated benzene, toluene, and ethylbenzene have been estimated by measuring values of the octanol-water partition coefficient (Kow) and HPLC retention factors (k1), which correlate closely to values of Koc. Measured values …
