Anwendungen
BeschreibungTriacetonamine (CAS 826-36-8), also known as 2,2,6,6-tetramethyl-4-piperidone or TAA, is a key intermediate in the synthesis of HALS (hindered amine light stabilisers); Their ability to effectively inhibit polymer degradation by scavenging free radicals is based on their sterically hindered amine functional groups, which are capable of forming stable N-oxides as active intermediates (the Denysov cycle). TAA is also used in the synthesis of pharmaceuticals, piperidine nitroso radicals and pyrrolidone derivatives. For example, the oxidation of TAA or its derivatives yields the corresponding tetramethylpiperidine-N-oxide, namely TEMPO; the latter can be used as a polymerisation inhibitor, molecular weight regulator or oxidation catalyst[2].
Verwenden2,2,6,6-Tetramethyl-4-piperidinone (cas# 826-36-8) is a compound useful in organic synthesis.
