Bis(4-hydroxyphenyl) Sulfone CAS 80-09-1
Bisphenol S (BPS), nambala ya CAS 80-09-1 ndi dzina la mankhwala Bis(4-hydroxyphenyl) Sulfone, ndi mankhwala onunkhira omwe ali ndi kapangidwe ka bisphenol kolumikizidwa ndi gulu la sulfone. Chifukwa cha polarity yamphamvu ndi kukhazikika kwa gulu la sulfone (-SO₂-) m'mapangidwe ake a mamolekyulu, magwiridwe ake amasiyana kwambiri ndi a bisphenol A (BPA), zomwe zimapangitsa kuti igwiritsidwe ntchito kwambiri m'mafakitale a mankhwala, zipangizo, ndi mankhwala tsiku ndi tsiku.

1. Zipangizo za Polima: Ma Monomers ndi Zosintha Zapakati
Kupangidwa kwa Epoxy Resin: Monga bisphenol A replacement monomer, imalumikizana ndi epichlorohydrin kuti ipange "bisphenol S-type epoxy resin." Utomoni uwu umawonetsa kukana kutentha kwambiri (kutentha kwa kusintha kwa galasi (Tg) 30-50°C kuposa bisphenol A epoxy resin), kukana dzimbiri, ndi mphamvu ya makina. Bis(4-hydroxyphenyl) sulfone imagwiritsidwa ntchito mu zipangizo zamagetsi zopaka kutentha kwambiri, zomatira zomangira ndege, ndi zokutira za mankhwala zotsutsana ndi dzimbiri.
Kupanga kwa Polycarbonate (PC): Imagwiritsidwa ntchito popanga "bisphenol S-type PC," zomwe zimapangitsa kuti zipangizo za PC zisamavutike kutentha komanso kuti zisawonongeke ndi UV. Ndi yoyenera kugwiritsidwa ntchito monga nyumba zowunikira panja komanso madenga a magalimoto.
Kusintha kwa Polysulfone Resin: Bis(4-hydroxyphenyl) sulfone imagwiritsidwa ntchito ngati comonomer popanga polysulfone resins, zomwe zimapangitsa kuti resin isagwire bwino ntchito komanso kuti isamagwire bwino ntchito. Imagwiritsidwa ntchito m'zida zamankhwala zapamwamba kwambiri (monga ma dialyzer) ndi ma electronic component housing.
2. Mankhwala ndi Nsalu Zatsiku ndi Tsiku: Zowonjezera Zogwira Ntchito
Zipangizo Zokongoletsera: Bis(4-hydroxyphenyl) sulfone imawonjezeredwa ku zodzoladzola za dzuwa ndi zinthu zosamalira khungu ngati choyamwa UV kapena antioxidant. Pogwiritsa ntchito mphamvu zoteteza ku dzuwa za gulu la phenolic hydroxyl komanso kukhazikika kwa gulu la sulfone, imachepetsa kuwonongeka kwa UV pakhungu ndikuwonjezera nthawi yogwiritsira ntchito mankhwalawa.
Chothandizira pa nsalu: Bis(4-hydroxyphenyl) sulfone imagwiritsidwa ntchito popanga zinthu zoletsa moto kapena zinthu zoletsa kutentha. Pogwirizana ndi magulu a hydroxyl pamwamba pa ulusi kuti apange mgwirizano wokhazikika, zimapangitsa kuti nsaluyo ikhale yoletsa kutentha komanso yoletsa kutentha. Yoyenera nsalu monga zovala zantchito ndi makatani.
3. Zipangizo Zolumikizira Chakudya ndi Mapulasitiki: Bisphenol A Cholowa M'malo
Zipangizo Zophikira Chakudya: Bisphenol S imagwiritsidwa ntchito popanga zokutira za epoxy resin zapamwamba pa chakudya (monga zokutira mkati mwa zitini) ndi mapulasitiki olumikizirana chakudya (monga mabotolo a ana ndi mbale za patebulo). Chifukwa cha kusamuka kwake kochepa, imagwirizana ndi miyezo yachitetezo cha kukhudzana ndi chakudya monga EU Directive 10/2011 ndi China GB 4806.
Kuphimba Mapepala Otentha: Monga cholowa m'malo mwa BPA, chimagwiritsidwa ntchito limodzi ndi utoto wa leuco ndi opanga utoto wa mapepala otentha (monga mapepala olembetsera ndalama ku supermarket ndi zilembo zotumizira mwachangu) kuti BPA isasamukire m'thupi la munthu kudzera pakhungu.
4. Ntchito Zina
Mankhwala Othandizira: Bisphenol S imagwiritsidwa ntchito popanga mankhwala omwe ali ndi mphamvu yotsutsa kutupa komanso yoletsa mabakiteriya.
Ma Analytical Chemical Reagents: Bisphenol S imagwiritsidwa ntchito ngati chizindikiro cha acid-base kapena chosinthira complexing pakusanthula kuchuluka kwa ma ayoni achitsulo (monga chitsulo ndi mkuwa). Gulu la phenolic hydroxyl limapanga complex yokhazikika ndi ma ayoni achitsulo, zomwe zimapangitsa kusintha kwa mtundu.
Asidi wamphamvu:Molekyulu ya Bisphenol S ili ndi magulu awiri a phenolic hydroxyl ndi gulu limodzi lamphamvu la sulfone lotulutsa ma electron (-SO₂ -), zomwe zimapangitsa kuti ikhale ndi asidi wambiri kuposa ma phenols wamba.
Kuyankha kwa phenolic kwachizolowezi:Magulu awiri a phenolic hydroxyl mu molekyulu ya Bis(4-hydroxyphenyl) Sulfone ali ndi reactivity yayikulu ndipo amatha kuchita zinthu zosiyanasiyana monga etherification, esterification, ndi polycondensation, mwachitsanzo, kuchitapo kanthu ndi formaldehyde kuti apange resin.
Kukhazikika kwabwino:Bis(4-hydroxyphenyl) Sulfone imakhala ndi kukana kutentha, kukana okosijeni komanso kukhazikika kwa kuwala, koma imatha kuwola pansi pa asidi wamphamvu, alkali wamphamvu kapena mikhalidwe yamphamvu ya okosijeni.
Kukhazikika kwa kutentha kwambiri:Kutentha kwa kutentha kwa Bisphenol S kuli pamwamba pa 300℃, zomwe zimasonyeza kukhazikika bwino panthawi yokonza kutentha kwambiri.
Kuchepa kwa poizoni:Bisphenol S ndi chinthu chopanda poizoni wambiri.
Bisphenol S ingagwiritsidwe ntchito m'malo mwa bisphenol A:Chifukwa cha zoopsa zomwe zingachitike chifukwa cha bisphenol A pa thanzi, bisphenol S ingagwiritsidwe ntchito m'malo mwake popanga zinthu zambiri monga polycarbonate ndi epoxy resin, ndipo zinthu zambiri zopangidwa zimakhala ndi kutentha kwambiri, kukhazikika kwa mankhwala komanso mphamvu zamakanika.
