Was ist TEMPO?<\/strong><\/h2>\n

2,2,6,6-Tetramethylpiperidinoxid, abgek\u00fcrzt TEMPO, ist ein Piperidin-Nitroxid-Radikal. TEMPO ist orangerot, leicht zu sublimieren, kristallin oder fl\u00fcssig und leicht l\u00f6slich in L\u00f6sungsmitteln wie Wasser, Ethanol und Benzol.<\/h4>\n

Es hat die Funktion, freie Radikale einzufangen und Singulett-Sauerstoff zu l\u00f6schen, und ist ein sehr wirksamer Oxidationskatalysator, der prim\u00e4re Alkohole zu Aldehyden und sekund\u00e4re Alkohole zu Ketonen oxidieren kann.<\/h4>\n

Aufgrund der sterischen Hinderungswirkung der vier Methylgruppen ist TEMPO relativ licht- und hitzebest\u00e4ndig und ein sehr effektiver Oxidationskatalysator, der prim\u00e4re und sekund\u00e4re Alkohole zu den gew\u00fcnschten Carbonylverbindungen oxidieren kann. Er zeichnet sich durch eine hohe Ausbeute, gute Selektivit\u00e4t, gute Stabilit\u00e4t und Wiederverwertbarkeit aus.<\/h4>\n

2,2,6,6-Tetramethylpiperidinooxy \/ TEMPO Verwendung<\/strong><\/h2>\n

1. Die katalytische Oxidation von Cellulose mit TEMPO gilt als effektive Methode. Sie kann die Struktur der Lignocellulosefasern in ihrem Suspensionsreaktionssystem vollst\u00e4ndig oxidieren und eine gute Grundvoraussetzung f\u00fcr die anschlie\u00dfende mechanische Dissoziation schaffen.<\/h4>\n

2. TEMPO ist ein wasserl\u00f6sliches, stabiles Nitroxylradikal. Es kann zur selektiven Katalyse der Oxidation der prim\u00e4ren Hydroxylgruppen von Polysacchariden verwendet werden, um diese in Carboxylgruppen umzuwandeln.<\/h4>\n

3. Kontakt mit dem Reaktionsoxidationsmittel, das f\u00fcr die Jodbenzoldiacetyl-Oxidation von Nerol zur Herstellung von Nerol verwendet wird. Kurz gesagt, Kupfer\/TEMPO wird f\u00fcr die Kontaktreaktion von Alkohol in 1-Position zu Aldehyd verwendet.<\/h4>\n
