概要

論文の詳細を見る
The concentration of liver oils by the solvent extraction was already studied by Dombrow, Buxton, Gloyer, Passino and Abe etc., but they have little studied on the method for selecting the solvent. To find the suitable solvent in the concentration of liver oils, chromatography method was proposed by the authors, and the results are summerizedas follows: (1) The chromatography method is useful for selecting the solvent of liver oils. (2) Aniline and picoline have the possibility as the new solvent in the concentration of liver oils, if it is possible to separate out the solvents from the liver oils in any way. (3) It is considered that the solvent actions of furfural and of isopropanol are due to not only Van der Waals force but also mutual action of π-electrons in the unsaturated bond.
