He pēhea te tauhohenga o te Whakapūtanga Phenol me te Acetone mō te Hanga BPA?
Ka pāngia te Phenol me te acetone e te tauhohenga whakapūpū i raro i te whakakorikori o tētahi reo waikawa hei whakaputa i te Bisphenol A BPA. Kāore i te uaua te tauhohenga matua, ā, he ngawari noa ngā āhuatanga tauhohenga. Ka taea te haere pai i te pēhanga noa me te 60 - 90 °C. Kāore i te roa te tukanga whakaputa o te BPA, e whā ngā wāhanga matua: te tauhohenga whakapūpū, te whakatiotanga tāpiri, te tango me te purenga o te phenol, me te whakaora i te waikura whaea. Heoi, he tino teitei ngā whakaritenga kounga o te BPA polycarbonate, me neke atu i te 99.5% te parakore, he iti iho i te 5 × 10⁻⁵ te wāhanga papatipu phenol, he iti iho i te 20 te tae APHA, me ngā herenga ki te ira tio, te pungarehu, ngā katote rino, me ētahi atu. Nā te mea he matū tairongo wera me te hāora te Bisphenol A BPA me te ira kohua teitei (360.5 °C), he maha ngā raruraru hangarau matū e pā ana ki te whakaputa i te Bisphenol A BPA kounga teitei e kawea mai ana e ēnei āhuatanga.
