    摘要: The invention relates to a method for preparing free polyunsaturated fatty acids and their oxidation metabolites, wherein, successively, the production of polyunsaturated fatty acids and of their oxidation metabolites is stimulated, in a red alga, by the action of an elicitor which is peptide, lipid or saccharide in nature, and then the polyunsaturated fatty acids produced and also their oxidation metabolites are extracted.

    摘要: The sodium fluoroalcoholates are prepared under conditions resulting in neither reactant nor final product degradation, by (a) reacting, under reflux, the corresponding fluoroalcohols, e.g., the mono-, di- or trifluoroethanols, with sodium methanolate in the presence of a solvent having a boiling point higher than that of methanol and/or a solvent which forms an azeotrope with methanol, and (b) selectively trapping the methanol of reaction, e.g., in a molecular sieve, as it is released into the vapors which evolve upon refluxing the step (a) reaction mixture; the sodium fluoroalcoholates thus produced are well suited for direct reaction with polydichlorophosphazenes.
