Cov txheej txheem tsim khoom ntawm bisphenol A yog dab tsi?

Kev Sib Piv ntawm Txoj Kev Resin thiab Hydrogen Chloride Method Technologies
(1) Cov txiaj ntsig ntawm cov txheej txheem resin rau bisphenol A bpa① Tsis tas yuav siv cov khoom siv kim heev uas tiv taus xeb, thiab kev nqis peev rau cov khoom siv tsawg; ② Cov dej khib nyiab tsawg dua tsim tawm; ③ Cov catalyst tsis tas yuav rov qab tau thiab rov ua dua tshiab.
(2) Cov txiaj ntsig ntawm cov txheej txheem hydrogen chloride rau bisphenol A bpa: ① Cov catalyst muaj kev ua haujlwm siab, qhov kub ntawm cov tshuaj tiv thaiv qis, thiab ob peb yam tsis huv tau tsim; ② Tus nqi hloov pauv khoom siv raw yog siab; ③ Cov acetone tsis tau ua haujlwm tsis tas yuav rov ua dua tshiab; ④ Qhov ntim phenol ncig mus rau hauv lub reactor yog qhov tsawg tshaj plaws (lub txaj tsis raug thaiv), thiab cov ortho thiab para isomers hauv lub reactor tsis crystallize; ⑤ Tsis tas yuav recrystallization, txo cov nqi peev thiab cov nuj nqis khiav lag luam; ⑥ Tus nqi ntawm cov khoom by-product tsim los ntawm lub reactor yog me me, thiab tsis tas yuav tsum muaj lub cuab yeej hloov pauv khoom hnyav.
Lub hom phiaj ntawm qhov zoo ntawm kev ua haujlwm catalyst thiab kev xaiv ntawm txoj kev hydrogen chloride, txoj kev ion-exchange resin tau txhim kho cov catalyst, thiab cov tshuaj tiv thaiv condensation tau ua tiav ntawm qhov sib piv phenol-ketone loj. Phenol yog ob qho tib si reactant thiab cov tshuaj tiv thaiv, uas txhim kho qhov kev xaiv ntawm cov tshuaj tiv thaiv condensation. Cov khoom tsis huv hauv cov khoom tshuaj tiv thaiv condensation tuaj yeem sib cais los ntawm cov txheej txheem crystallization kom tau txais cov khoom zoo bisphenol A bpa. Hauv cov nqe lus ntawm tus lej ntawm cov khoom siv, txoj kev resin zoo ib yam li txoj kev hydrogen chloride. Tib lub sijhawm, cov txheej txheem ion-exchange resin tau hloov pauv qhov tsis zoo ntawm cov txheej txheem hydrogen chloride, muaj kev xeb tsis zoo rau cov khoom siv, thiab txhim kho kev ntseeg siab ntawm kev ua haujlwm ntawm lub cev yam tsis nce cov nqi peev. Yog li ntawd, txoj kev ion-exchange resin rau kev tsim bisphenol A bpa tau dhau los ua cov thev naus laus zis tseem ceeb thiab kev coj ua.
