For example, for PS in tetrahydrofuran (THF), the relationship between molecular weight and radius of gyration ([R.sub.g]) is described by the following equation (3) [52]:
To a solution of 4-ethynylbenzaldehyde (3) (42.2 mg, 0.32 mmol, 1.2 equiv.), obtained starting from 4-[(trimethylsilyl)ethynyl]benzaldehyde [25], and terthiophene derivative (2) (88.5 mg, 0.27 mmol, 1 equiv.) in degassed tetrahydrofuran (6mL), [Pd[Cl.sub.2][(P[Ph.sub.3]).sub.2]] (7.6 mg, 4mol%), Cul (3.1 mg, 6mol%), and triethylamine (1.5 mL) were added, under a flow of nitrogen.
In the present study, we report the results of density [rho], viscosity [eta], and speed of sound u for the binary mixtures of methyl benzoate with ethers, namely, tetrahydrofuran, 1,4-dioxane, anisole, and butyl vinyl ether measured at (303.15, 308.15, and 313.15)K over the entire mixture composition.
Incipient wetness technique was used for filling the spheres by dissolving eight grams of sodium alanate in 100 ml of tetrahydrofuran (Sigma Aldrich).
Daiwon Choi [27] reported a room temperature process for the fabrication of HAP using organic solvent such as tetrahydrofuran. Spherical HAP particles were formed with diameter between 1 and 10 mm using tetrahydrfuran.
1 and 2, is that for Dictyonema oil shale, the highest swelling extents can be seen in specifically interacting solvents (in hydrogen bonding solvents with high EDN values, such as pyridine, NMP, tetrahydrofuran, propylamine), and this emphasizes the concern regarding the use of regular-solution based approaches.
Unlike other gels held together by relatively weak forces, the new gel kept its shape even after sitting in the solvent tetrahydrofuran for six hours.
Other solvents did solubilize more than 60% of the contamination, such as THF (tetrahydrofuran), Methoxy-Propoxy-Propanol (DMP) and Butyl-acetate.
