Cov xwm txheej khaws cia rau bisphenol A yuav tsum tig mus rau lub hom phiaj tseem ceeb ntawm "kev tiv thaiv kev puas tsuaj, kev ua kom muaj kev nyab xeeb, thiab kev zam kev cuam tshuam rau ib puag ncig".

Kev siv Bisphenol A (BPA)

Bisphenol A (BPA) yog ib yam khoom siv tseem ceeb rau kev tsim cov polycarbonates, epoxy resins, thiab polyesters uas tiv taus kub siab. Nws kuj tseem siv tau ua PVC stabilizer, yas antioxidant, UV absorber, fungicide, thiab lwm yam.
Ua ib qho tshuaj sib xyaw ua ke, BPA siv dav hauv kev tsim cov epoxy resins, polycarbonates, polyester resins, polyphenylene ether resins, thiab polysulfone resins. Tsis tas li ntawd, nws ua haujlwm ua tus stabilizer rau polyvinyl chloride (PVC), ib qho antioxidant hauv plastics, ib qho UV absorber, ib qho fungicide ua liaj ua teb, thiab ib qho anti-aging agent hauv roj hmab.
Nws kuj siv ua cov tshuaj antioxidant thiab plasticizer hauv cov xim thiab cov kua mem. Hauv cov organic synthesis, BPA ua haujlwm ua cov khoom tseem ceeb rau kev tsim cov epoxy thiab polycarbonate resins, thiab nws tau siv dav ua cov khoom siv tseem ceeb rau cov tshuaj synthetic siab-molecular, nrog rau cov neeg sawv cev tiv thaiv kev laus, cov yas, thiab cov tshuaj fungicides ua liaj ua teb.

Bisphenol a bpa Acid-Catalyzed Txheej Txheem
Hauv cov txheej txheem acid-catalyzed, cov catalysts feem ntau yog sulfuric acid, hydrochloric acid, lossis hydrogen chloride gas.
Cov txheej txheem siv sulfuric acid ua tus catalyst muaj qhov ntws yooj yim, tsim tawm hauv ib lub lauj kaub, ua haujlwm tsis tu ncua, tsis tas yuav rov qab tau phenol, thiab muaj kev nqis peev tsawg. Txawm li cas los xij, nws muaj ntau yam khoom seem, tsis zoo bisphenol A bpa, siv ntau, ntau peb cov khib nyiab (roj pov tseg, dej pov tseg, thiab cov khib nyiab khov), xeb cov khoom siv hnyav, thiab cov txiaj ntsig qis. Txoj kev sulfuric acid tau raug tshem tawm txawv teb chaws hauv xyoo 1960.
Txoj kev siv hydrochloric acid lossis hydrogen chloride roj ua tus catalyst hu ua hydrochloric acid method. Txoj kev hydrochloric acid muaj cov txheej txheem tsim khoom loj hlob thiab tuaj yeem tsim tawm tsis tu ncua lossis tsis tu ncua. Kev siv cov khoom siv raw thiab kev tsim kho pej xeem tsawg, thiab cov khoom tuaj yeem ua tiav qhov zoo tom qab kev ua kom huv, uas yog siv rau hauv kev tsim cov polycarbonate. Vim yog qhov muaj zog corrosiveness ntawm hydrochloric acid, cov khoom siv xav tau rau cov khoom siv, cov kav dej, thiab cov cuab yeej yog siab, yog li cov nqi peev thiab kev saib xyuas yog siab. Ib yam li txoj kev sulfuric acid, peb qhov pov tseg yog qhov loj heev. Cov txheej txheem hydrochloric acid yog txoj kev tsim khoom tseem ceeb hauv ntiaj teb hauv xyoo 1970 thiab 1980.
