Ukunyibilika: kuncibilika kalula kuzincibilikisi zemvelo ezifana notshwala, ama-ester, ama-alkanes, ama-hydrocarbon anephunga elimnandi, njenge-ethanol, i-acetone, i-acetate ye-butyl, uphethiloli, i-toluene, njll. Incibilika kancane emanzini, inyibilika esixazululweni se-alkali esiqinile.
Ukuzinza: Lo mkhiqizo unezici ezivamile zezinto ze-phenolic.Uma uchayeke ekukhanyeni, ekushiseni, noma emoyeni, umbala uzojula kancane kancane.
Isicelo Esiyinhloko
I-P-tert-butylphenol ine-antioxidant futhi ingasetshenziswa njengesiqinisi serabha, insipho, ama-hydrocarbons ane-chlorine kanye nemicu egayiwe.Ama-absorber ama-UV, ama-anti-cracking anjengemithi yokubulala izinambuzane, irabha, amapende, njll. Isibonelo, isetshenziswa njengesizinzisi se-polycarbon resin, i-tert-butyl phenolic resin, i-epoxy resin, i-polyvinyl chloride, ne-styrene.Ngaphezu kwalokho, kuphinde kube yimpahla eluhlaza yokwakhiwa kwemithi exosha izinambuzane, i-acaricide Kmitt, izinongo kanye nama-ejenti okuvikela izitshalo.Ingasetshenziswa futhi njengezithambisi, izincibilikisi, izithasiselo zikadayi nopende, ama-antioxidants kumafutha okugcoba, okokususa amasimu kawoyela kanye nezithasiselo zamafutha ezimoto.
Indlela Yokukhiqiza
Kunezindlela ezine zokwenza i-tert-butyl phenol:
(1) Indlela ye-Phenol isobutylene: sebenzisa i-phenol ne-isobutylene njengezinto zokusetshenziswa, i-cation exchange resin njenge-catalyst, futhi wenze ukusabela kwe-alkylation ku-110 ° C ngaphansi kwengcindezi evamile, futhi umkhiqizo ungatholakala nge-distillation ngaphansi kwengcindezi encishisiwe;
(2) Indlela ye-Phenol diisobutylene;usebenzisa i-silicon-aluminium catalyst, ekucindezelweni kokuphendula kwe-2.0MPa, izinga lokushisa lika-200 ° C, nokuphendula kwesigaba se-liquid, i-p-tert-butylphenol itholakala, kanye ne-p-octylphenol ne-o-tert-butylphenol.Umkhiqizo wokusabela uhlukaniswe ukuze uthole i-p-tert-butylphenol;
(3) Indlela yengxenye ye-C4: usebenzisa ingxenyenamba ye-C4 ephukile kanye ne-phenol njengezinto zokusetshenziswa, kusetshenziswa i-titanium-molybdenum oxide njenge-catalyst, ukusabela kuthola ingxube ye-phenol alkylation reaction ne-p-tert-butylphenol njengengxenye eyinhloko, futhi umkhiqizo etholwe ngemva kokuhlukana;
(4) Indlela ye-Phosphoric acid catalyst: i-phenol ne-tert-butanol isetshenziswa njengezinto zokusetshenziswa, futhi umkhiqizo ungatholakala ngokuwasha nokuhlukaniswa kwe-crystallization.
[Uchungechunge lwezimboni] I-Isobutylene, i-tert-butanol, i-phenol, i-p-tert-butylphenol, ama-antioxidants, izinzile, imithi, izibulala-zinambuzane nezinye izinto zokwenziwa eziphilayo.
Ukupakisha, Isitoreji kanye Nezokuthutha
Igcwele ifilimu ye-polypropylene ehlanganiswe nesikhwama sephepha esingenakukhanya njengongqimba olungaphandle, kanye nesigubhu sekhadibhodi esiqinile.25kg/drum.Gcina endaweni epholile, engenamoya, eyomile, nemnyama.Ungawubeki eduze kwamapayipi amanzi kanye nezinto zokushisisa ukuze uvimbele umswakama nokushisa.Gwema umlilo, ukushisa, ama-oxidants, nokudla.Amathuluzi okuthutha kufanele ahlanzeke, ome, futhi agweme ukukhanya kwelanga nemvula ngesikhathi sokuthutha.
