Ɔkwan bɛn so na Phenol&Acetone Condensation for BPA Production yɛ n’ade?

Phenol ne acetone fa condensation reaction mu wɔ acidic medium catalysis ase ma ɛyɛ Bisphenol A BPA. Ade titiriw a wɔyɛ no nyɛ den, na tebea horow a ɛma wɔyɛ ade no nyɛ den koraa. Mpɛn pii no ebetumi akɔ so yiye wɔ nhyɛso a ɛfata ne 60 - 90 °C mu. BPA a wɔyɛ no nkyɛ, na ɛwɔ afã anan titiriw: condensation reaction, adduct crystallization, phenol a woyi fi hɔ na ɛho tew, ne ɛna nsa a wɔsan nya. Nanso, polycarbonate - grade BPA wɔ ahwehwɛde a ɛkorɔn yiye, ɛhwehwɛ sɛ ɛho tew bɛboro 99.5%, phenol mass fraction a ennu 5 × 10−5, APHA kɔla a ennu 20, ne anohyeto ahorow a ɛfa freezing point, ash, iron ions, ne nea ɛkeka ho Esiane sɛ Bisphenol A BPA yɛ a PAPAt - adeɛ a ɛyɛ mmerɛw na ɛyɛ oxygen - a ɛyɛ hyew a ɛkorɔn paa (360.5 °C), saa su yi de nnuruyɛ ho haw pii ba Bisphenol A BPA a ɛyɛ papa a wɔyɛ mu.
