Bisphenol A mboibelekela antoomwe a phosgene kuchita polycarbonate

Bisphenol A Kuswaangana kwa BPA a Phosgene — Kubamba Polycarbonate
Kuswaangana kwa bisphenol A BPA a phosgene nintaamu mpati mukubamba polycarbonate. Mukusanduka ooku, atomu ya carbonyl carbon mu phosgene ilijisi nguzu zyamagesi, mpawo atomu ya phenolic hydroxyl oxygen ya bisphenol A ibelekela mbuli busena bwakulwana, akupanga chintu chili akati-akati. Mpawo, chintu chili akati-akati chisweekelwa molecule yomwe ya hydrogen chloride mpawo chizumanana kuswaangana ama molecule aambi aa bisphenol A BPA antoomwe a phosgene, asyoonto-asyoonto kazipanga polycarbonate. Ooku kusanduka kanjikanji kuchitwa muchintu chiyumu, mpawo asidi-binding agent yeelede kusanganyigwa kuti inywe hydrogen chloride iizwa mukusanduka kuchitila kuti kusanduka kuchitike munzila iili kabotu. Ziimo zyakusanduka ziindene, zilimbuli musyobo wa musamu wakusandula, kusala kwa asidi-binding agent, antoomwe achiindi chakusanduka, zyoonse ziyoojatikizya bubotu akubeleka kwa polycarbonate. Mbuli chitondeezyo, kusala chintu chili kabotu chakusanzya zintu zipona kulakonzya kugwasya kuti zintu zipangwa kazikonzya kunywika akupa kuti kusanduka kweende kabotu; chintu chili kabotu chakujata asidi chilakonzya kuyoya kabotu haayidirojeni chloride, kubamba asidi a alkalinity ya nzila yakusanduka, akusinizya kuti nzila yakusanduka kweenda kabotu.
