Para Tert Octylphenol
PARA TERT OCTYLPHENOL (P-Tert-Octyl Phenol) (PTOP)
Code: UN Code: 3077
CAS Nr . 140-66-9
HS Code: 2907139000
Core Properties (Piv rau p-tert-Butylphenol)
Stronger Steric Hindrance thiab Solubility:Vim tias tert - pawg octyl loj dua, ntau hydrophobic, thiab roj ntau dua -soluble dua li tert-butyl pawg, p-tert-octylphenol pov thawj:
Solubility zoo nyob rau hauv cov organic solvents thiab roj.
Ntau tshaj tawm steric hindrance cuam tshuam,ntxiv cuam tshuam rau nws cov reactivity (xws li, ua ortho hloov txawm nyuaj dua).
Tsawg Volatility thiab Thermal Stability:Lub cev hnyav dua molecular ua rau qhov kub siab dua, ua rau nws ruaj khov dua thaum ua thiab siv, tsis tshua muaj siab rau volatilization poob.
Similar Chemical Reactivity:Khaws cov acidity thiab reactivity ntawm phenolic hydroxyl pawg, ua rau nws yog ib qho zoo heev intermediate rau synthesizing ntau yam derivatives.
Main Industrial Siv
Nws daim ntawv thov feem ntau sib tshooj nrog cov p-tert-butylphenol, tab sis nyob rau hauv qee qhov kev thov siab dua -, nws qhov kev ua tau zoo ua rau nws nyiam lossis tshwj xeeb raw khoom.
A. Polymer Kev Lag Luam (Core Application)
Qhov no yog nws lub khw lag luam hauv qab.
1. Synthesis of p-tert-Octylphenolic Resins:Condensation nrog formaldehyde ua roj-soluble phenolic resins. Cov resins no ua tau zoo tshaj p-tert-butylphenolic resins, feem ntau hauv:
Siab thermal stability thiab antioxidant zog.
Cov nyhuv tackifying zoo dua thiab kev sib raug zoo, tshwj xeeb tshaj yog kev sib raug zoo nrog cov tsis yog -polar polymers (piv txwv li, SIS, SBS-raws li kub yaj siab- cov nplaum nplaum, thiab ntau cov roj hmab).
Tsawg xim thiab tsw, haum rau siab - kawg, lub teeb - cov khoom xim.
Daim ntawv thov: Dav siv los ua tackifying thiab hloov cov resins rau kub yaj siab- cov nplaum nplaum, cov nplaum kub yaj, cov roj hmab vulcanizing cov neeg ua haujlwm, sealants, thiab coatings. Nws yog cov khoom siv tseem ceeb rau kev tsim cov ntawv siab- kawg, daim kab xev, cov khoom siv tu cev (piv txwv li, daim ntaub kaw cov ntaub qhwv), thiab cov ntaub qhwv cov ntaub nplaum.
2. Phenolic Resin Modifier:Siv los txhim kho qhov yooj yim thiab solubility ntawm dav -lub hom phiaj phenolic resins.
B. Fine Chemicals
1. Surfactant Precursor:Cov tshuaj tiv thaiv nrog ethylene oxide tsim alkylphenol ethoxylates, chav kawm ntawm nonionic surfactants. Txawm li cas los xij, vim tias nws cov metabolite (octylphenol) tau lees paub tias yog qhov cuam tshuam endocrine, qhov kev siv no tau raug txwv nruj lossis txwv thoob ntiaj teb (tshwj xeeb hauv EU thiab Tuam Tshoj) hauv cov khoom xws li tshuaj ntxuav tes thiab cov khoom tu tus kheej uas yooj yim tso rau hauv ib puag ncig. Nws siv tam sim no tau tso cai tsuas yog nyob rau hauv kev tswj hwm nruj hauv cov tshuab kaw.
2. Intermediate rau Antioxidants thiab Stabilizers:Ua haujlwm ua ib qho nruab nrab rau kev sib txuas ntawm qee yam siab -kev ua tau zoo, siab -molecular- hnyav hindered phenolic antioxidants thiab UV absorbers.
3. Lwm tus:Siv rau hauv kev tsim cov tshuaj tshwj xeeb hauv kev lag luam xws li lubricant additives thiab tshuaj tua kab emulsifiers.
