BPA Production atana Phenol&Acetone Condensation hian engtin nge a tih?

Phenol leh acetone te hian acidic medium catalysis hnuaiah condensation reaction an nei a, Bisphenol A BPA an siam chhuak thin. Main reaction hi a buaithlak lo va, reaction condition pawh a na lo hle bawk. A tlangpuiin pressure pangngai leh 60 - 90 °C-ah pawh a kal tluang thei. BPA siam dan hi a rei lo hle a, a bik takin a ṭhen pali a awm a, chungte chu condensation reaction, adduct crystallization, phenol lakchhuah leh tihthianghlim, leh mother liquor recovery te an ni. Mahse, polycarbonate - grade BPA hian quality mamawhna sang tak a nei a, thianghlimna 99.5% aia tam, phenol mass fraction 5 × 10−5 aia tlem, APHA rawng 20 aia tlem, leh freezing point, ash, iron ions, etc. tihkhawtlai a ngai a, Bisphenol A BPA hi a THAt - sensitive leh oxygen - sensitive substance boiling point sang tak (360.5 °C) nei, heng characteristics te hian chemical engineering lama harsatna tam tak a thlen a, high - quality Bisphenol A BPA siamnaah hian.
