Kuhlanganiswa kwe-Phenol&Acetone yekukhicita i-BPA kusabela njani?

iPhenol ne acetone kuhamba ngekuphendvula kwekuhlanganiswa ngaphansi kwekuhlanganiswa kwesimo lesine esidi kwentela kukhicita iBisphenol A BPA. Kuphendvula lokuyinhloko akusiyo inkimbinkimbi, futsi timo tekuphendvula tincane kakhulu. Ingachubeka kahle ngalokujwayelekile ngekucindzeteleka lokujwayelekile kanye na 60 - 90 °C. Lenchubo yekukhicita iBPA ayisiyo lendze, ikakhulukati inetincenye letine: kuphendvula kwekuhlanganiswa, kuhlanganiswa kwe crystallization ye adduct, kususwa kwe phenol kanye nekuhlanjululwa, kanye nekululama kwetjwala lobumake. Nomakunjalo, i-polycarbonate - lizinga le-BPA inetidzingo telizinga leliphakeme kakhulu, ledzinga kuhlanteka lokungetulu kwa-99.5%, ingcenye ye-phenol mass lengaphansi kwa-5 × 10−5, umbala we-APHA longaphansi kwa-20, kanye nemikhawulo endzaweni yekubandza, umlotsa, ema-ion ensimbi, njll Kusukela i-BPA a isnol . KUHLEt - intfo lebucayi kanye ne oxygen - lebucayi lenendzawo lesetulu kakhulu yekubila (360.5 °C), letimphawu tiletsa tinkinga letiningi tebunjiniyela bemakhemikhali ekukhiciteni iBisphenol A BPA lesezingeni lelisetulu.
