Butanol acetic acid water solvent system
WebA “phase diagram” of the type shown is required for all commonly used three-component paper chromatographic solvent mixtures to facilitate the design of one-phase solvents for particular problems. Mixtures of -butanol, glacial acetic acid, and water were studied with this concept in mind. Cited by (0) WebAn upper layer of a mixture of n-butanol, acetic acid and water (4:1:5, v/v). d A mixture of equal volumes of acetone and benzene. The recovery test was performed with riboflavin. The fluorescence intensity of lumi fl avin obtained with a definite amount (1.0ƒÊg) was compared with that obtained from silica
