I-Phenol&Acetone Condensation for BPA Production yenza njani?

I-Phenol ne-acetone yenza ukusabela kokuncibilika ngaphasi kokukhuthazwa kwe-asidi ukukhiqiza i-Bisphenol A BPA. Ukuphendula okukhulu akusibudisi, begodu ubujamo bokuphendula bulula. Ngokuvamileko ingaragela phambili kuhle ngomfutho ovamileko kanye nama-60 - 90 °C. Ikambiso yokukhiqiza i-BPA ayide, ikakhulukazi ineengcenye ezine: ukusabela kokuncibilika, ukukhiqizwa kwe-adduct, ukususwa kwe-phenol nokuhlanzwa, nokubuyiswa kotshwala obungumama. Kodwana, i-polycarbonate - grade BPA ineemfuneko zekhwalithi ephezulu khulu, efuna ukuhlanzeka okungaphezu kwama-99.5%, i-phenol mass fraction engaphasi kwe-5 × 10⁻⁵, umbala we-APHA ongaphasi kwe-20, kanye nemikhawulo yephuzu lokuqanda, umlotha, ama-ayoni wensimbi, njll. Njengombana i-Bisphenol i-BPA FANELEt - into ezwelako ne-oksijini - enezinga eliphezulu lokubila (360.5 °C), ubujamo lobu buletha imiraro eminengi yobunjiniyela bamakhemikhali ekukhiqizeni i-Bisphenol A BPA yekhwalithi ephezulu.
