Uyini umkhiqizo we-Bisphenol A?

I-Bisphenol A (i-bpa) Isingeniso

I-Bisphenol A (BPA), eyaziwa nangokuthi i-2,2-bis(4-hydroxyphenyl)propane, iyisithako esiyinhloko se-phenol ne-acetone. Yenziwa ngezimboni ngokujiya kwe-phenol ne-acetone lapho kukhona izinto ezibangela ukwakheka njenge-mercaptoacetic acid, i-chloroacetic acid, i-barium hydroxide, noma kusetshenziswa ama-ion exchange resins. Iyinto ebalulekile yamakhemikhali e-organic.

Ukusabela Kokufiphaza:
2 C₆H₅OH (Phenol) + (CH₃)₂C=O (I-Acetone) → (C₆H₄OH)₂C(CH₃)₂ (I-Bisphenol A) + H₂O

I-Bisphenol A – iphayona lokumelana nokushisa elinezinga lokuncibilika elingu-155-158°C, lihlala liqinile ezindaweni ezishisa kakhulu. Chofoza lapha ukuze uthole amanani ancishisiwe.
