Kodi njira ya Bisphenol a bpa Hydrochloric Acid ndi chiyani?
Bisphenol a bpa Njira ya Hydrochloric Acid
Njira zogwiritsira ntchito hydrochloric acid kapena hydrogen chloride gasi monga ma catalysts zimatchedwa njira ya hydrochloric acid. Mwachitsanzo, chisakanizo cha phenol ndi acetone chimayanjanitsidwa ndi hydrogen chloride catalyst youma pa mpweya woipa ndi 50–60°C kwa maola 8-9. Pamene voliyumu ya hydrogen chloride ya gasi ikupitirira 96%, chinthu chachikulu ndi bisphenol A bpa, yokhala ndi zinthu zina kuphatikizapo ma isomers ake, trihydroxy, kapena monohydroxy derivatives.
Bisphenol A bpa yomwe yapezeka pogwiritsa ntchito njira iyi ingagwiritsidwe ntchito ngati zinthu zopangira epoxy resin. Kuyeretsa kwina kumafunika ngati ikugwiritsidwa ntchito pa polycarbonate. Mwachitsanzo, njira ya Hooker imayeretsa bisphenol A pogwiritsa ntchito vacuum distillation ndi extractive crystallization. Mitengo yogwiritsidwa ntchito pa tani imodzi ya bisphenol A bpa ndi pafupifupi matani 0.855 a phenol, matani 0.269 a acetone, matani 0.216 a hydrogen chloride, ndi matani 0.011 a benzene solvent.
Njirayi ndi yodziwika bwino ndipo ingagwiritsidwe ntchito m'njira zosiyanasiyana monga batch kapena continuous production modes.
