W pierwszym etapie kwasy tłuszczowe

W pierwszym etapie kwasy tłuszczowe, zwłaszcza nienasycone i/lub lipidy lub alkohole
nienasycone, korzystnie olej roślinny, poddaje się utlenianiu w temperaturze pokojowej.
Stosuje się wodne roztwory utleniaczy organicznych lub nieorganicznych, bądź ich
mieszanin. Proces utleniania prowadzi się w środowisku kwasów, zwłaszcza nieorganicz-
nych, w obecności rozpuszczalników hydrofobowych. Najczęściej poddaje się utlenianiu
olej słonecznikowy wodnym roztworem nadmanganianu potasu w środowisku kwasu
siarkowego w obecności heksanu lub heptanu. W procesie tym uzyskuje się rozwarstwie-
nie na dwie fazy: wodną i organiczną. Fazę wodną usuwa się, a organiczną przesącza i
oddestylowuje pod ciśnieniem niższym od atmosferycznego, korzystnie poniżej 40 hPa,
uzyskując składnik podstawowy.
W drugim etapie przygotowuje się w temperaturze 70°C - 100°C roztwór związków
selenu w rozpuszczalniku, korzystnie dioksanie. Stosuje się związki zawierające selen
na czwartym stopniu utlenienia, zwykle kwas selenawy.

結果 (英文) 1:

In the first stage of the fatty acids, especially unsaturated and/or lipids or alcohols insatiable, vegetable oil, is subjected to oxidation at room temperature. Apply aqueous solutions of organic and inorganic oxidants, or their mixtures. The oxidation process is carried out in an environment of acids, in particular nieorganicz-, in the presence of hydrophobic solvents. Most frequently subjected to oxidation sunflower oil of water solution of potassium permanganate in acid environment sulphur in the presence of hexane or heptane. This process is achieved bond strength and delamina-not on two phases: aqueous and organic. The aqueous phase is removed, and an organic filtrate and oddestylowuje at a pressure lower than atmospheric, preferably below 40 hPa, by obtaining a core component.In the second stage, getting ready at 70 ° c-100 ° c solution compounds Selenium in the solvent, preferably dioksanie. Applies to compounds containing selenium on the fourth degree of oxidation, usually acid selenawy.

In a first step the fatty acids, especially unsaturated and / or lipid, or alcohols,
unsaturated, preferably a vegetable oil, is subjected to oxidation at room temperature.
Using aqueous solutions of organic or inorganic oxidants, or their
mixtures. The oxidation process is carried out in an acid, in particular inorganic
different, in the presence of hydrophobic solvents. Most by the oxidation
of sunflower oil with an aqueous solution of potassium permanganate in a medium of
sulfuric acid in the presence of hexane or heptane. In this process the delamination
is not two phases: an aqueous and organic phase. The aqueous phase was removed and the organic was filtered and
evaporated under sub-atmospheric pressure, preferably below 40 mbar,
to give the base component.
In the second phase is prepared at 70 ° C - 100 ° C the solution of
selenium in a solvent, preferably dioxane. Compounds containing selenium
in the fourth oxidation state, typically selenious acid.
