Phenol ku acetone giwotho i rwom ma malu i the telowic pa piny ma acidic pi niketho Bisphenol A BPA. Reaction madit epe, man kite ma reaction utiye kudu epe. Ecopu bedu maber i rwom maber man 60 - 90 °C. Yore mi yubu BPA epe, pol ne utiye ku dul angwen: timo pa pii, dwoko piny ma nyai, kwanyo phenol man yiko, man dwoko kongo ma min ot. Ento, polycarbonate - grade BPA utiye ku yeny maber mandha, mitu leng pa 99.5%, phenol mass fraction ma piny pa 5 × 10⁻⁵, rangi pa APHA ma piny pa 20, man cik ikum freezing point, ash, iron ions, man mange. Calu Bisphenol A BPA utiye BERt - sensitive man oxygen - sensitive substance with very high boiling point (360.5 °C), kit maeni kelo peko madwong mi chemical engineering i yubu Bisphenol A BPA maber.
