Xana Bisphenol a bpa Ndlela ya Hydrochloric Acid i yini?
Bisphenol ya A bpa Ndlela ya Asidi ya Hydrochloric
Maendlelo lawa ya tirhisaka hydrochloric acid kumbe gasi ya hydrogen chloride tani hi swihlohloteri hinkwaswo ya vuriwa ndlela ya hydrochloric acid. Xikombiso, nkatsakanyo wa phenol na acetone wu endliwa na dry hydrogen chloride catalyst eka ntshikelelo wa xibakabaka na 50–60°C kuringana 8–9 wa tiawara. Loko xiphemu xa volume xa gaseous hydrogen chloride xitshama ehenhla ka 96%, xiendliwa lexikulu i bisphenol A bpa, na swihumelerisiwa leswi katsaka ti isomers ta yona, trihydroxy, kumbe monohydroxy derivatives.
Bisphenol A bpa leyi kumiwaka hi ndlela leyi yinga tirhisiwa tani hi raw material eka vuhumelerisi bya epoxy resin. Ku basisiwa kun’wana swa laveka loko ku ta tirhisiwa eka polycarbonate. Endlelo ra Hooker, hi xikombiso, ri antswisa bisphenol A hiku tirhisa vacuum distillation na extractive crystallization. Mimpimo ya ku tirhisiwa hi thani ya bisphenol A bpa yi kwalomu ka 0.855 wa tithani ta phenol, 0.269 wa tithani ta acetone, 0.216 wa tithani ta hydrogen chloride, na 0.011 wa tithani ta benzene solvent.
Ndlela leyi yi simekiwile kahle naswona yinga tirhisiwa eka maendlelo ya batch kumbe ya vuhumelerisi lebyi yaka emahlweni.
