dioxane การใช้

• In this way, dioxane is used to drive the Schlenk equilibrium.
• Usually toluene, dioxane, tetrahydrofuran or acyclic dialkylethers are employed as solvents.
• The compound is derived from dioxane by dehydrogenation.
• PEGs contain potential toxic impurities, such as ethylene oxide and 1, 4-dioxane.
• While diethyl ether is rather insoluble in water, dioxane is miscible and in fact is hygroscopic.
• It is insoluble in benzene but soluble in dioxane, from which it crystallizes as yellow needles.
• By 1991, the company had eliminated 1, 4-dioxane by changing its formula for solvents.
• Soil and groundwater had been contaminated with the volatile organic compounds trichloroethylene and 1, 4-Dioxane.
• SO 3 is a strong Lewis acid readily forming crystalline complexes with pyridine, dioxane, and trimethylamine.
• Figure 3 : Chains in the 1 : 1 adduct of 1, 4-dioxane and bromine.
• In 1985, the global production capacity for dioxane was between 11, 000 and 14, 000 tons.
• It is a colorless low-melting compound, which is soluble in water, dioxane, and alcohols.
• In crystal form, three conformers occur as hemiacetal dimers with a 1, 4-dioxane ring skeleton:
• While the FDA encourages manufacturers to remove 1, 4-dioxane, it is not required by federal law.
• Scanio found that changing the solvent of the reaction from dioxane to DMSO gives different stereochemistry in step D above.
• It is an oxide of carbon ( an oxocarbon ), which can be viewed as the fourfold ketone of dioxane.
• The reference I would like to change says : ^ " CHEC Chemical Summary : 1, 4-dioxane ".
• Like other dialkylmagnesium compounds, it is prepared by adding at least one equivalent of dioxane to a solution of methylmagnesium halide:
• The dioxolane is expanded to the 1, 3-dioxane system found in sporol at a later step in the synthesis.
• They include polyoxyethyleneamines, which irritate the respiratory tract, eyes and skin, and a byproduct, dioxane, a suspected carcinogen.
