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:
High molecular weight, essentially uncrosslinked polychlorophosphazenes are prepared by bulk polycondensing a monomer of the formula P.sub.2 NXCl.sub.2, in which X is an oxygen or sulfur atom, e.g., N-dichlorophosphoryl- or N-dichlorothiophosphoryl-P-trichlorophosphazene, and wherein at least that final stage of polycondensation following cessation of evolution of PXCl.sub.3 is carried out in a stirred reaction zone, such stirred reaction zone including means to prevent the accumulation of polycondensate on the stirrer.
摘要:
Crude polyorganophosphazenes, produced by the nucleophilic cosubstitution of polydichlorophosphazenes and contained in a reaction medium which includes such polyorganophosphazenes, reaction solvent for the cosubstitution reaction, excess nucleophilic reagent and/or product of neutralization thereof, and, when present, any alkali metal salts of neutralization, are efficiently and facilely purified, in a single treatment zone, advantageously under agitation in a discontinuous malaxator, by both eliminating the reaction solvent and thereafter washing the resulting reaction medium with a liquid which is a nonsolvent for the polyorganophosphazenes, but miscible with the other products present in said reaction medium.

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.
