Solubility: yooj yim soluble nyob rau hauv organic solvents xws li cawv, esters, alkanes, muaj ntxhiab hydrocarbons, xws li ethanol, acetone, butyl acetate, roj av, toluene, thiab lwm yam. Me ntsis soluble nyob rau hauv dej, soluble nyob rau hauv muaj zog alkali tov.
Kev ruaj ntseg: Cov khoom no muaj cov yam ntxwv ntawm cov tshuaj phenolic.Thaum raug lub teeb, cua sov, los yog huab cua, xim yuav maj mam sib sib zog nqus.
Daim ntawv thov tseem ceeb
P-tert-butylphenol muaj cov khoom siv antioxidant thiab tuaj yeem siv los ua kom ruaj khov rau roj hmab, xab npum, chlorinated hydrocarbons thiab digested fibers.UV absorbers, anti-cracking agents xws li tshuaj tua kab, roj hmab, xim, thiab lwm yam. Piv txwv li, nws yog siv los ua ib tug stabilizer rau polycarbon resin, tert-butyl phenolic resin, epoxy resin, polyvinyl chloride, thiab styrene.Tsis tas li ntawd, nws tseem yog cov khoom siv raw rau kev tsim cov tshuaj tua kab mob, tshuaj tua kab acaricide Kmitt, txuj lom thiab tshuaj tiv thaiv cov nroj tsuag.Nws kuj tseem siv tau ua softeners, solvents, additives rau dyes thiab xim, antioxidants rau lubricating roj, demulsifiers rau roj teb thiab additives rau tsheb fuels.
Txoj kev tsim khoom
Muaj plaub txoj hauv kev ua tert-butyl phenol:
(1) Phenol isobutylene txoj kev: siv phenol thiab isobutylene li raw cov ntaub ntawv, cation txauv resin li catalyst, thiab nqa tawm alkylation cov tshuaj tiv thaiv ntawm 110 ° C nyob rau hauv ib txwm siab, thiab cov khoom yuav tau los ntawm distillation nyob rau hauv lub siab txo;
(2) Phenol diisobutylene txoj kev;siv cov silicon-aluminium catalyst, ntawm cov tshuaj tiv thaiv siab ntawm 2.0MPa, qhov kub thiab txias ntawm 200 ° C, thiab cov tshuaj theem ua kua, p-tert-butylphenol tau txais, nrog rau p-octylphenol thiab o-tert-butylphenol.Cov tshuaj tiv thaiv cov khoom sib cais kom tau txais p-tert-butylphenol;
(3) C4 feem txoj kev: siv tawg C4 feem thiab phenol ua raw cov ntaub ntawv, siv titanium-molybdenum oxide raws li ib tug catalyst, cov tshuaj tiv thaiv tau ib tug sib tov ntawm phenol alkylation cov tshuaj tiv thaiv nrog p-tert-butylphenol ua lub ntsiab tivthaiv, thiab cov khoom yog tau tom qab sib cais;
(4) Phosphoric acid catalyst method: phenol thiab tert-butanol yog siv los ua cov khoom siv raw, thiab cov khoom tuaj yeem tau txais los ntawm kev ntxuav thiab crystallization sib cais.
[Industrial saw] Isobutylene, tert-butanol, phenol, p-tert-butylphenol, antioxidants, stabilizers, tshuaj, tshuaj tua kab thiab lwm yam khoom siv hluavtaws.
Ntim, Cia thiab thauj
Nws yog packed nrog ib tug polypropylene zaj duab xis lined nrog ib lub teeb-pov thawj daim ntawv lub hnab raws li txheej txheej, thiab ib tug nruj cardboard nruas.25kg / nruas.Khaws rau hauv qhov chaw txias, cua txias, qhuav, thiab tsaus warehouse.Tsis txhob muab tso rau ze ntawm cov kav dej thiab cov khoom siv cua sov kom tsis txhob dampness thiab kub deterioration.Khaws kom deb ntawm hluav taws, cua sov, oxidants, thiab zaub mov.Cov cuab yeej thauj mus los yuav tsum huv, qhuav, thiab tsis txhob tshav ntuj thiab nag thaum caij tsheb thauj mus los.
