Ino Phenol&Acetone Condensation for BPA Production ilachita biyeni?

Phenol a acetone zilainda mukusanduka kwakutontola aansi aakusungwaazyigwa kwa asidi kuti zipange Bisphenol A BPA. Ikusanduka kupati takuli kukatazya pe, mpawo bukkale bwakusanduka tabuli kabotu pe. Chilakonzya kweenda kabotu-kabotu a 60 - 90 °C. Nzila yakupanga BPA tiili chiindi chilamfu pe, ikapati ilijisi zibeela zyone: kusanduka kwakutontola, kusanduka kwa adduct, kugwisya phenol akusalazya, antoomwe akubweedezya bukoko. Nokuba boobo, polycarbonate - grade BPA ilaa zyeelelo zibotu loko, ziyandika kusalala kwiinda 99.5%, phenol mass fraction iitasiki ku 5 × 10⁻⁵, mubala wa APHA uutasiki ku 20, alimwi akulesyegwa kwa freezing point, ash, iron ions, azimwi. Mbwaanga Bisphenol A BPA NCHIBOTUt - chintu chilimvwisya a oxygen - chili aanguzu zyakupya kapati (360.5 °C), eezyi zipa kuti kube mapenzi manji aakupanga makemikalu mukupanga Bisphenol A BPA iili kabotu.
