2,2,6,6-Tetramethyl-4-piperidinol CAS 2403-88-5
2,2,6,6-Tetramethyl-4-piperidinol mea he keʻokeʻo crystalline pauka i ka lumi wela, hoʻoheheʻe 'ia i loko o ka organic solvents e like me ka acetone, ethanol, a me ka chloroform, iki i ka wai, a he hygroscopicity. Loaʻa iā ia ka photostability a loaʻa nā noi nui i nā lāʻau lapaʻau. ʻO nā mea hoʻokūpaʻa māmā amine i hoʻopaʻa ʻia i kēia manawa ʻo ka polymer material light stabilizers maikaʻi loa, a he papa o nā pūhui amine organik me nā hopena steric hindrance.

Hoʻohana ʻia ʻo 2,2,6,6-Tetramethyl-4-piperidinol ma ke ʻano he kikowaena nui no nā mea hoʻonaninani māmā amine a me ka synthesis o nā stabilizers māmā amine. Hiki ke hoʻohana ʻia ma ke ʻano he koʻikoʻi koʻikoʻi no nā lāʻau lapaʻau, bleaching agents, epoxy resin crosslinkers, a me nā huahana ʻē aʻe. ʻO 2,2,6,6-Tetramethyl-4-piperidinol i kēia manawa ka mea hoʻomohala wikiwiki loa i hoʻohana ʻia no ka anti-aging o nā mea polymer e like me ka plastics a me ka rubber.
Hoʻopili pinepine ʻia i ka 25kg / pahu, a hiki ke hana ʻia i ka pōʻai maʻamau.
