    Xana Phenol&Acetone Condensation ya Vuhumelerisi bya BPA yi endla njhani?

    2. 2.025-11-04

    Phenol na acetone swi endla condensation reaction ehansi ka catalysis ya acidic medium kuva yi humesa Bisphenol A BPA. Ku angula lokukulu a ku rharhangananga, naswona swiyimo swa ku angula a swi olovi ngopfu. Hi xitalo yinga famba kahle eka ntshikelelo wa ntolovelo na 60 - 90 °C. Endlelo ra vuhumelerisi bya BPA ari lehi, ngopfu ngopfu rivumbiwa hi swiphemu swa mune: condensation reaction, adduct crystallization, ku susiwa ka phenol naku basisiwa, xikan’we naku vuyiseriwa ka byala bya manana. Hambiswiritano, polycarbonate - grade BPA yina swilaveko swa khwalithi yale henhla swinene, yi lava ku basa kutlula 99.5%, phenol mass fraction yale hansi ka 5 × 10−5, muhlovo wa APHA wale hansi ka 20, na swipimelo eka freezing point, ash, iron ions, etc. Tanihi leswi Bisphenol A BPA yinga a KAHLEt - nchumu lowu nga na vuxiyaxiya na oxygen - lowu nga na nhlayo ya le henhla swinene yo vila (360.5 °C), swihlawulekisi leswi swi tisa swiphiqo swo tala swa vunjhiniyara bya tikhemikhali eka vuhumelerisi bya khwalithi ya le henhla ya Bisphenol A BPA.
