Tetrahydrofuran is at the growth stage and is expanding rapidly across the globe especially in the Asia pacific region owing to the expanding textile industry.
Nain, "Densities and volumetric properties of binary mixtures of tetrahydrofuran with some aromatic hydrocarbons at temperatures from 278.15 to 318.15 K," Journal of Solution Chemistry, vol.
20 g polyvinylidene chloride (PVDC) was slowly added into the mixture of 800 mL saturated KOH ethanol solution (25 mass.%) and 1200 mL tetrahydrofuran (THF).
As for solvents, toluene, benzene, and tetrahydrofuran (THF) were chosen due to the Flory-Huggins polymer-solvent (P-S) interaction parameters ([[chi].sub.P-S]) calculated with PS and PDEAEM, namely, 0.347 and 0.350 for toluene, 0.341 and 0.380 for benzene, and 0.34 and 0.36 for THF, values that are very similar to both polymers indicating that in this solvent there is only a slight or not a solvating preference for one of the blocks.
Solvents were dried by standard procedures: tetrahydrofuran (THF) and toluene were freshly distilled from Na/benzophenone under nitrogen atmosphere; N,N-dimethylformamide (DMF) was dried over activated molecular sieves; triethylamine ([Et.sub.3]N) was freshly distilled over KOH.
The following materials, among others, have been found at the facility: acetone, dimethyl formamide, petroleum ether, tetrahydrofuran, dichloroethyl ether, benzene, toluene, perchloric acid and phosphorus pentachloride.
The specimens were divided into groups of 20 and cleaned using 10% hydrofluoric acid, 35% phosphoric acid, 50% hydrogen peroxide, acetone, dichloromethane, ethanol, isopropanol, or tetrahydrofuran. The last 5 agents were used neat.
This sensor can detect acetone, chloroform, cyclohexane, N,N-dimethylformide, ethanol, ethyl acetate, hexane, methanol, carbon tetrachloride, tetrahydrofuran, and toluene.
The placement of the tetrahydrofuran ring in acetogenin was determined by analysis of the mass fragmentation pattern.
One milligram of the acetylated WE was dissolved in 1 mL of tetrahydrofuran and subjected to gel permeation chromatography (GPC) analysis.
