We want to extract terpenoids from an aqueous sample by continuous liquid-liquid extraction. Which of the following solvents is not suitable for this purpose? Why? Propanone (acetone), dichloromethane, heptane.
Each of the solvents given should effectively separate one of the following mixtures by TLC. Match the appropriate solvent with the mixture that you would expect to separate well with that solvent. Select your solvent from the following: hexane, methylene chloride, or acetone. You may need to look up the structures of solvents and compounds in a handbook.a. 2-Phenylethanol and acetophenoneb. Bromobenzene and p-xylenec. Benzoic acid, 2,4-dinitrobenzoic acid, and 2,4,6-trinitrobenzoic acid
For the synthesis of isoamyl acetate by Fischer esterification, some common solvents that form azeotropes with water will be incompatible with the reaction conditions. Indicate for each of these whether the solvent is suitable or unsuitable for azeotropic removal of water from the reaction mixture. Benzene, butanoic acid, n-butanol, butyl ether, cyclohexane, cyclohexanol, ethyl acetate, heptane, pyridine, toluene
how do you separate three organic substances by means of extraction. If the three substances, one is 4-methoxyphenol, one acid, the other substance, 1-phenylethylamine, is a base and the third substance, 1,4-dimethoxybenzene, lacks acid-base properties. The three substances are dissolved in diethyl ether, which is a relatively non-polar organic solvent
How do you construct a flow chart using extraction to separate a mixture of the 3 solids used below if dicholoromethane is the solvent and any other reagents can be used. The 3 solids are: pyrazole, p-chlorobenzoic acid, and benzophenone.

To determine the purity of a synthetic preparation of methylethyl ketone, C4H8O, it was reacted with hydroxylamine hydrochloride, liberating HCl (reaction: NH2OH.HCl + C4H8O -> C4H9NO + H20 + HCl). In a typical analysis a 3.00-mL sample was diluted to 50.00 mL and treated with an excess of hydroxylamine hydrochloride. The liberated HCl was titrated with 1.2149 M NaOH, requiring 35 mL to reach the end point. A. Write the acid base reaction involved in the titration. B. Report the percent purity of the sample given that the density of methylethyl ketone is 0.805 g/mL.
