Übersetzung für 'osmium tetroxide' von Englisch nach Deutsch

osmium tetroxide [OsO4]

Osmiumtetroxid {n}chem.

• Other fixatives used for electron microscopy are osmium tetroxide or uranyl acetate.
• It is common practice to perform this reaction using a catalytic amount of osmium tetroxide, which after reaction is regenerated with reoxidants such as potassium ferricyanide or "N"-methylmorpholine "N"-oxide.
• The major types are oxidizing agents such as osmium tetroxide, reducing agents such as lithium aluminium hydride, bases such as lithium diisopropylamide and acids such as sulfuric acid.
• Several variations on the method exist to increase contrast or selectivity in the type of neuron stained, and include additional impregnation in mercuric chloride solution (Golgi-Cox) or post-treatment with osmium tetroxide (Cajal or rapid Golgi).
• Two more hydroxyl groups were added by oxidation of the newly formed double bond with a catalytic amount of osmium tetroxide in the presence of N-methylmorpholine N-oxide.

• The picture was obtained on a thin film of polymer cast onto mercury from solution, and then stained with osmium tetroxide.
• This heterocyclic amine oxide and morpholine derivative is used in organic chemistry as a co-oxidant and sacrificial catalyst in oxidation reactions for instance in osmium tetroxide oxidations and the Sharpless asymmetric dihydroxylation or oxidations with TPAP.
• This uses a catalytic loading of osmium tetroxide which is regenerated in situ by the periodate.
• With the asymmetric oxyamination reaction, using osmium tetroxide, being the earliest.
• Examples of such solutes are noble gases and osmium tetroxide.

• When he isolated osmium tetroxide – a rather toxic chemical – he described its taste as astringent and pepper-like.
• He named it osmium after Greek "osme" meaning "a smell", because of the ashy and smoky smell of the volatile osmium tetroxide.
• Osmium tetroxide is used in optical microscopy to stain lipids.
• The ruthenium tetroxide is very similar to osmium tetroxide; the ruthenium compound is a stronger oxidant which enables it to form deposits by reacting with other substances.
• Using alkaline potassium manganate(VII) produces a colour change from clear deep purple to clear green; acidic potassium manganate(VII) turns clear colourless. Osmium tetroxide can similarly be used to oxidize alkenes to vicinal diols.

• An example of syn addition would be the oxidation of an alkene to a diol by way of a suitable oxidizing agent such as osmium tetroxide, [...] , or potassium permanganate, [...].
