Alcohols, unsaturated solvent parameters

The most pronounced change in relative adsorptivity with a change in solvent was observed (77) for the pair of substrates unsaturated alcohol-unsaturated hydrocarbon. The sorption of olefins was preferred in polar solvents (low values of the parameter ), while in nonpolar solvents (high values of the same parameter) unsaturated alcohols were preferably sorbed. An explanation may be seen in an interaction between the solvent and the... [Pg.360]

The Crismer value (CV) measures the miscibility of an oil in a standard solvent mixture, composed of f-amyl alcohol, ethyl alcohol, and water in volume proportion 5 5 0.27 (Table 13). This parameter is one of the specification criteria used for international trade, mostly in Europe however, today it is rarely used. The values obtained are characteristic within a narrow limit for each kind of oil. The miscibility of oil is related to the solubility of acylglycerols and is affected mainly by the unsaturation and chain length of the constituent fatty acids. [Pg.718]
