Antioxidant 565; AO 565; ADNOX 565 rau polymers
cov khoom nthuav dav
Lub npe tshuaj: 2,6-di-tert-butyl-4—(4,6-bis(octylthio)-1,3,5-triazin-2-ylamino)phenol Cov Lus Txhais: Irganox 565, Songnox 5650; Antioxidant 565; AO 565 CAS No.: 991-84-4 Chemcial Structure: Tswb Dawb hmoov los yog pellet Assay ≥98% Melting point 91-96 ℃ Volatility 105 ℃ 2hours ≤0.5% Pob: 25KG Carton Daim Ntawv Thov ADNOX® 565 yog qhov hnyav molecular; non-staining, multifunctional antioxidant tsim rau stabilization ntawm unsaturated elastomers (BR, IR, SBR, SIS, SBS, thiab lwm yam), kub yaj adhesives, thiab rosin ester tackifier resins. Background Antioxidant 565 yog ib qho polymer multifunctional hindered phenolic antioxidant, feem ntau yog tsim rau tom qab ua kom ruaj khov ntawm cov roj hmab tsis zoo, zoo heev rau cov elastomers, thiab tuaj yeem tiv thaiv cov ntaub ntawv los ntawm kev tsim khoom, ua thiab siv zaum kawg. Thermal oxidative degradation. Nws yog ib qho zoo heev antioxidant thiab photothermal stabilizer rau ntau yam resins. Nws muaj cov yam ntxwv ntawm qhov sib ntxiv me me, tsis tshua muaj hluav taws xob, xim nrawm nrawm, thiab tuaj yeem tiv thaiv kev tsim cov gel. Siv tau zoo heev hauv cov elastomers nram qab no: cis-butadiene roj hmab (BR) isoprene roj hmab (IR) styrene-butadiene roj hmab (SBR) nitrile-butadiene roj hmab (NBR) carboxylated styrene-butadiene latex emulsion polystyrene-butadiene roj hmab (ESBR) kua polymerization Styrene-butadiene roj hmab (BSBR) thermostatic roj hmab thermoplastic styrene-butadiene roj hmab SIS kuj tuaj yeem siv rau cov nplaum, cov khoom siv ntuj tsim thiab hluavtaws, xws li EPDM, ABS yas, polyamide (nylon, PA), siab Impact polystyrene (HIPS) thiab polyolefins. ABS yas yog ib qho kev hloov kho polystyrene yas tsim los ntawm peb yam khoom raws li acrylonitrile (A), butadiene (B) thiab styrene (S). ABS yas siv tau los ua cov yas zoo nkauj boards nrog embossed qauv, thiab lwm yam. Lub synthesis ntawm Antioxidant 565 yog soj ntsuam nyob rau hauv no dissertation. 2,6-di-tert-butylphenol, raws li thawj substrate, yog nitrated rau 2,6-di-tert-butyl-4-nitrophenol nyob rau hauv 95% tawm los. 2,6-di-tert-butyl-4-nitrophenol txo mus rau 4-amion -2,6-di-tert-butylphenol nrog hydrogen nyob rau hauv muaj Raney Ni los yog Pd / C. Txhawm rau tiv thaiv kom tsis txhob decomposition ntawm 4-amion -2,6-di-tert-butylphenol thaum raug huab cua, 4-amion -2,6-di-tert-butylphenol raug tso cai rau cov tshuaj nrog Cyanuric chloride yam tsis muaj kev sib cais rau daim ntawv 6-(3,5-di-tert-butyl-4-hydroxy) laniline-2,5%-1,4-3. yield rau 2 kauj ruam. Cov tshuaj tiv thaiv ntawm 6-(3,5-di-tent-butyl-4-hydroxy) aniline-2,4-dichloro-1,3,5-triazin nrog 2 qhov sib npaug ntawm n-Octylthiol muab cov khoom kawg 6-(3,5-di-tert-butyl-4-hydroxy aniline-2,4-inthios)-octylthiol 94% tawm.
