Solubility: faigofie soluble i solvents organic pei o ava malosi, esters, alkanes, hydrocarbons aromatic, e pei o le ethanol, acetone, butyl acetate, penisini, toluene, ma isi. Laititi soluble i le vai, soluble i le malosi alkali solution.
Tulaga mautu: O lenei oloa ei ai uiga masani o mea phenolic.Pe a faʻaalia i le malamalama, vevela, poʻo le ea, o le lanu o le a faasolosolo malie ona loloto.
Talosaga Autu
O le P-tert-butylphenol o lo'o i ai mea fa'aantioxidant ma e mafai ona fa'aoga e fai ma fa'amautu mo pa'u, fasimoli, chlorinated hydrocarbons ma alava fa'amama.UV absorbers, anti-cracking agents e pei o vailaau faʻasaina, paʻu, vali, ma isi. Mo se faʻataʻitaʻiga, e faʻaaogaina e fai ma faʻamautu mo polycarbon resin, tert-butyl phenolic resin, epoxy resin, polyvinyl chloride, ma styrene.E le gata i lea, o le mea faʻapitoa foʻi mo le gaosiga o vailaau faʻamaʻi iniseti, vailaʻau faʻamaʻi Kmitt, mea manogi ma mea e puipuia ai laau.E mafai foi ona faʻaaogaina e pei o faʻamaluluina, solvents, additives mo vali ma vali, antioxidants mo lubricating suauʻu, demulsifiers mo suauʻu fanua ma additives mo suauu taavale.
Metotia Gaosiga
E fa auala e fai ai tert-butyl phenol:
(1) Phenol isobutylene auala: faʻaaoga le phenol ma le isobutylene e fai ma mea mata, cation exchange resin e fai ma faʻamalosi, ma faʻataunuʻuina le alkylation i le 110 ° C i lalo o le mamafa masani, ma e mafai ona maua le oloa e ala i le faʻamamaina i lalo o le faʻaitiitia o le mamafa;
(2) Metotia phenol diisobutylene;faʻaaogaina o le silicon-aluminum catalyst, i se faʻalavelave faʻafefe o le 2.0MPa, o le vevela o le 200 ° C, ma le faʻaogaina o le vaega vai, e maua ai le p-tert-butylphenol, faʻapea foʻi ma le p-octylphenol ma le o-tert-butylphenol.E tuueseese le oloa tali e maua ai le p-tert-butylphenol;
(3) C4 vaega ninii auala: faʻaaogaina le vaega C4 taʻe ma phenol e pei o mea mata, faʻaaogaina o le titanium-molybdenum oxide e fai ma faʻamalosi, o le tali e maua ai se faʻafefiloi o le phenol alkylation faʻatasi ma le p-tert-butylphenol e avea ma vaega autu, ma o le oloa o le maua ina ua tete'a ；
(4) Phosphoric acid catalyst method: phenol ma tert-butanol o loʻo faʻaaogaina e avea ma mea mata, ma e mafai ona maua le oloa e ala i le fufuluina ma le vavaeeseina o le tioata.
[Fa'ainisinia filifili] Isobutylene, tert-butanol, phenol, p-tert-butylphenol, antioxidants, stabilizers, vailaʻau, vailaau faʻasaina ma isi mea faʻapipiʻi faʻasolosolo.
Fa'apipi'i, Teuina ma Felauaiga
O loʻo faʻapipiʻiina i se ata polypropylene o loʻo faʻapipiʻiina i se taga pepa faʻamalama e pei o le pito i fafo, ma se pusa pepa malo malo.25kg/drum.Teu i totonu o se faleteuoloa malulu, fa'aalili, mago, ma pogisa.Aua ne'i tu'u i tafatafa o paipa vai ma mea fa'avevela ina ia puipuia ai le susu ma le fa'aleagaina o le vevela.Taofi ese mai le afi, vevela, oxidants, ma meaai.O mea faigaluega tau felauaiga e tatau ona mama, mago, ma aloese mai le susulu o le la ma timuga i le taimi o felauaiga.
