Lintlha tsa Bohlokoa tsa Taolo Tlhahisong ea Bisphenol A
Ha ho tluoa tabeng ea bohloeki ba thepa e tala, phenol le acetone, e le thepa e ka sehloohong e tala bakeng sa tlhahiso ea bisphenol A, li hloka taolo e tiileng holim'a bohloeki ba tsona. Bohloeki ba phenol ha boa lokela ho ba ka tlase ho 99.5%, 'me bohloeki ba acetone bo lokela ho fihla ho feta 99%. Lisebelisoa tse tala tse hloekileng haholo li ka fokotsa tšitiso ea litšila karabelong le ho netefatsa tsoelo-pele e boreleli ea karabelo.
Taolo ea mocheso oa karabelo ke ea bohlokoa. Mocheso oa karabelo ea condensation hangata o pakeng tsa 40 - 60°C. Ka har'a mofuta ona oa mocheso, sekhahla sa karabelo le khetho ea sehlahisoa li ka fihlela tekano e ntle. Lithempereichara tse phahameng haholo kapa tse tlase haholo li tla ama chai le boleng ba bisphenol A BPA. Mosebetsi le khetho ea catalyst li khetholla tataiso ea karabelo. Li-catalyst tse sebelisoang hangata tse kang sulfuric acid li hloka ho kenngoa ka nepo ha mahloriso le tekanyo ea tsona. Ka kakaretso, mahloriso a sulfuric acid a fetoha ka har'a mofuta o itseng, 'me tekanyo ke karolo e itseng ea kakaretso ea lisebelisoa tse tala, e le ho netefatsa hore catalyst e sebetsa hantle haholo. Khatello ea karabelo e boetse e ama tlhahiso ea bisphenol A BPA. Mofuta o nepahetseng oa khatello ke 0.5 - 1.5 MPa. Tikoloho e tsitsitseng ea khatello e thusa ho boloka botsitso ba sistimi ea karabelo le ho khothaletsa phetiso ea boima le tsoelo-pele ea karabelo. Karolelano ea thepa e amana ka ho toba le katleho ea karabelo. Karolelano ea molar ea phenol ho acetone hangata e laoloa ho 2.5 - 3.5:1. Karolelano e nepahetseng e ka etsa hore thepa e tala e arabele ka botlalo, ea eketsa chai ea bisphenol A BPA, le ho fokotsa lihlahisoa tse ling.

Phetoho ea Bisphenol A BPA e ntlafatsa matla a mechini, ho hanyetsa ho ngoapa le ho tsofala, e loketse ho sebetsana le liphephetso tse boima.

Haeba o batla ho reka dihlahiswa tse tshepahalang tsa dikhemikhale, ka kopo batla Shandong Pulisi Chemical Co., Ltd., e shebaneng le "khemikhale ya boleng bo hodimo" mme e se e ntse e sebetsa ka dilemo tse 20.
