    Bisphenol ya A (BPA) Xingheniso

    Bisphenol A (BPA), leyi tivekaka tani hi 2,2-bis(4-hydroxyphenyl)propane, i xitirhisiwa xa nkoka xa phenol na acetone. Yi endliwa hi ti indasitiri hiku hlanganisiwa ka phenol na acetone eka vukona bya ti catalysts tofana na mercaptoacetic acid, chloroacetic acid, barium hydroxide, kumbe hiku tirhisa ti ion exchange resins. I raw material ya nkoka ya ti khemikhali ta organic.

    Nhlamulo ya Condensation: .
    2 C2H5OH (Phenol) + (CH3)2C=O (Acetone) → (C6H4OH)2C(CH3)2 (Bisphenol A) + H2O

    Bisphenol A – phayona yo lwisana na kuhisa leyingana melting point ya 155-158°C, yitshama yirikarhi yi tiya kufana na ribye eka tindzhawu letingana mahiselo yale henhla.Tiklika laha kuva u kuma minxavo leyi hungutiweke.
