Kodi Phenol & Acetone Condensation for BPA Production imagwira ntchito bwanji?

Phenol ndi acetone zimakumana ndi condensation reaction pansi pa catalysis ya acidity medium kuti apange Bisphenol A BPA. Yankho lalikulu si lovuta, ndipo momwe zimachitikira zimakhala zofatsa. Nthawi zambiri zimatha kuyenda bwino pamlingo wabwinobwino komanso kutentha kwa 60 - 90 °C. Njira yopangira BPA si yayitali, makamaka yokhala ndi magawo anayi: condensation reaction, adduct crystallization, phenol removal ndi kuyeretsa, komanso mother alcohol recovery. Komabe, polycarbonate - grade BPA ili ndi zofunikira zapamwamba kwambiri, zomwe zimafuna chiyero choposa 99.5%, phenol mass fraction yosakwana 5 × 10⁻⁵, mtundu wa APHA wosakwana 20, komanso zoletsa pa malo ozizira, phulusa, iron ions, ndi zina zotero. Popeza Bisphenol A BPA ndi chinthu chomvera kutentha komanso mpweya chomwe chimakhala ndi malo otentha kwambiri (360.5 °C), makhalidwe awa amabweretsa mavuto ambiri aukadaulo wa mankhwala popanga Bisphenol A BPA yapamwamba kwambiri.
