analysis. The reorientational correlation time of toluene is dependent on the benzene mole fraction in the solution, whereas the correlation time of cyclohexane is independent of concentration. The benzene effect on the reorientation of toluene is interpreted in terms of the formation of benzene-...
Two color time of flight mass spectroscopy studies of toluene solvated by methane, ethane, and propane in a supersonic molecular jet have been carried out. This work is quite similar to the studies in the preceding paper on benzene. The conclusions and finding in the benzene investigation are ...

The rate of polymerization decreases in the order benzene > toluene > xylenes, inversely with the basicity of the solvent.117,296 Hexamethylbenzene, a strong electron donor, is capable of inactivating the polymerization if present in a suitable amount. Aliphatic solvents are also suitable, but ...
Noticeably, among these MS techniques, matrix-assisted laser desorption/ionization Fourier-transform ion cyclotron resonance mass spectrometry (MALDI FT-ICR MS) (that was traditionally applied for deciphering the structure of biological molecules) has emerged as a powerful tool for coke structural ...
Molecular beam mass spectrometry was used to measure mole fraction profiles of the reactants, major reaction products and intermediates, including precursors of polycyclic aromatic hydrocarbons, in a premixed fuel-rich (equivalence ratio of 1.75) n -heptane/toluene/O 2 /Ar flame stabilized on a ...
3a-gwith thiolactic acid and thioglycolic acid by stirring at room temperature for 16–20 h in the presence of catalytic amount of anhydrous zinc chloride and 1–4 dioxane. Structures of all the synthesized compounds were established on the basis of IR,1H NMR,13C NMR, and mass spectral ...
Article Molecular characterization of commercial polymers was published on January 1, 1971 in the journal Pure and Applied Chemistry (volume 26, issue 3-4).
If all the polymer chains are exactly the same, then the number average and weight average molecular weights are exactly the same and the PDI is “1.” The larger the molar-mass dispersity index the wider the molecular weight distribution. The molecular weight range can affect many properties ...
The nanoadsorbent was first synthesized via an in situ sonochemical oxidative polymerization method in the presence of FeCl3, as the oxidant, and other additives, including sodium dodecylbenzene sulfonate and ZnO nanoparticles (NPs). The use of an inorganic salt in the centrifugation step was ...
