Experimental equilibrium isotherms, Henry's law constants, and heats of sorption are reported for n-hexane, benzene, toluene, p-xylene, mesitylene, naphthalene, trimethylbenzene (TMP), and hexamethylbenzene (HMB) in La-exchanged zeolite Y (Si/Al = 1.8). Henry's law constants and energies of...
1.3.5Molecular weight Themolecular weightis simply the molecular weight of the repeat unit (MR) multiplied by the number of units in each chain (n): [1.1]M=nMR In most polymers, there are chains of different length, so two ways of defining the average are the number average and weight ...
The molecular structures of gaseous n-pentane, n-hexane and n-heptane have been investigated by the sector-microphotometer method of electron diffraction. The bond lengths for the molecules, in the above order, were found to be, in terms of center of gravity parameters rg: C-H = 1.118 ±...
Molecular dynamics method was used to simulate the binary system of n-hexane and l-butyl-3-methylimid- azolium thiocyanate ([BMIM] [SCN]). The density and viscosity of the system were obtained. Four radial distribution functions (i.e. n-hexane-n-hexan...

The new low molecular weight gelator 1 can reversibly form stable gels in low concentrations (e.g., 1:800 for n-hexane) with isopropanol and a variety of apolar organic solvents. The gels were studied with differential scanning calorimetry and a combination of electron microscopy techniques, ...
Living cationic polymerization of cisand trans〆thyl propenyl ethers and synthesis of block copolymers with isobutyl vinyl ether at 40°C in nonpolar media (toluene and n-hexane), led to living polymers of controlled molecular weights and a narrow molecular weight distribution (MWD... M Sawamoto,...
Size exclusion chromatography (SEC) was used to characterize the molecular weight distribution (MWD) of 6 low density and 6 high density food grade polyethylene resins. The hexane and xylene extractable fractions of these 12 resins were also analyzed by SEC. An IBM 370/168 computer with an APL...
Molecular dynamics simulations have been used to compute the surface tension of linear alkanes. The OPLS force field has been compared with the SKS force field for alkanes (n-hexane, n-decane and n-hexadecane) over two ranges of temperature: high temperatures where no experimental data are ...
