Beschreibung
2,2,6,6-Tetramethylpiperidine is a product that is used for the most diverse purposes because of its strong basicity, for example, as a light stabilizer for polyolefins, as a cocatalyst in olefin polymerizations (Ziegler catalysts), as a building block for the synthesis of pharmaceuticals and crop protection products, as a cocatalyst in the synthesis of dichloroacetyl chloride. The 4-unsubstituted 2.2.6,6-tetramethylpiperidine is generally prepared from the corresponding 4-oxo compound. It is known that triacetonamine can be converted by hydrazine to the hydrazone, which is then cleaved in the presence of alkali into 2,26,6-tetramethylpiperidine and nitrogen.Chemische Eigenschaften
orange crystals or powderCharakteristisch
2,2,6,6-Tetramethylpiperidinooxy(TEMPO) has the characteristics of high yield, good selectivity, good stability, and recyclable use.Verwenden
TEMPO(2,2,6,6-Tetramethylpiperidinooxy) is a stable radical prepared through the oxidation of 2,2,6,6-tetramethylpiperidine. TEMPO has a wide range of applications including use as a free radical scavenger, a reagent in organic synthe sis and as a structural probe in electron spin resonance spectroscopy. TEMPO can also be used as a mediator in free radical polymerization.Allgemeine Beschreibung
