Iyini i-2,2,6,6-Tetramethyl-4-piperidinol CAS 2403-88-5?

I-2,2,6,6-Tetramethyl-4-piperidinol iyimpushana emhlophe ecwebezelayo emazingeni okushisa asekamelweni, ancibilika kuzincibilikisi eziphilayo njenge-acetone, i-ethanol, ne-chloroform, encibilika kancane emanzini, futhi ine-hygroscopicity. Iphinde ibe ne-photostability futhi inezinhlelo zokusebenza ezibalulekile kwezemithi. Iziqinisi zokukhanya kwe-amine ezivinjiwe njengamanje ziyiziqinisi zokukhanya ezibonakalayo ze-polymer ezisebenza kahle kakhulu, futhi ziyikilasi lezinhlanganisela ze-organic amine ezinemiphumela yokuvinjwa kwe-steric.

Isicelo

I-2,2,6,6-Tetramethyl-4-piperidinol isetshenziswa njengendawo eyinhloko yeziqinisi ezivinjiwe zokukhanya kwe-amine kanye nokuhlanganiswa kweziqinisi zokukhanya kwe-amine ezivinjiwe. Ingasetshenziswa futhi njengendawo ebalulekile emaphakathi kwezemithi, ama-bleaching agents, ama-epoxy resin crosslinkers, neminye imikhiqizo. I-2,2,6,6-Tetramethyl-4-piperidinol okwamanje iyisinzinzisi esithuthuka ngokushesha esisetshenziselwa ukulwa nokuguga kwezinto ze-polymer ezifana namapulasitiki nenjoloba.
