Mokhoa oa Tlhahiso ea Glacial Acetic Acid
Ts'ebetso ea tlhahiso ea glacial acetic acid e ka aroloa ka mehato e latelang:
Tokisetso ea Lintho tse Tala: Lisebelisoa tse ka sehloohong tse tala bakeng sa glacial acetic acid ke ethanol le moemeli oa oxidizing. Hangata ethanol e fumanoa ka ho belisa kapa ho kopanya lik'hemik'hale, ha moemeli oa oxidizing hangata e le oksijene kapa hydrogen peroxide.
Karabelo ea Oxidation: Ethanol le moemeli oa oxidizing li fepuoa ka har'a sejana sa karabelo, moo karabelo ea oxidation e etsoang tlas'a mocheso o laoloang le khatello. Karabelo hangata e etsahala boteng ba catalyst ea asiti, e qalang ka oxidation ethanol ho acetaldehyde ebe e e oxidation ho ea ho acetic acid.
Phetoho ea Asiti ea Acetic: Acetaldehyde e fetoloa ka mokhoa oa catalytic hore e be asiti ea acetic. Ntho ea bohlokoa e bakang khase mohatong ona ke libaktheria tsa asiti ea acetic. Ka ho kopana le libaktheria tsena, acetaldehyde e fetoloa asiti ea acetic, ha carbon dioxide le metsi le tsona li hlahisoa e le lihlahisoa tse ling.
Ho Hloekisa Asiti ea Acetic: Motsoako o hlahang oa asiti ea acetic o ntse o hloekisoa haholoanyane. Mekhoa ea ho hloekisa e kenyelletsa ho qhibilihisa le ho etsa kristale. Ho qhibilihisa ho kenyelletsa ho arola asiti ea acetic ho tsoa motsoakong ka ho laola mocheso le khatello, ho hlahisa asiti ea acetic e hloekileng haholo. Ka lehlakoreng le leng, mokhoa oa ho etsa kristale o kenyelletsa ho eketsa tharollo e itseng ho etsa hore asiti ea acetic e qhibilihise ho ba likristale tse hloekileng tsa asiti ea acetic.
Pakete le Polokelo: Asiti e hloekisitsoeng ea acetic e pakoa, hangata ka har'a lijana tsa polasetiki kapa libotlolo tsa khalase. Asiti e pakoang ea acetic ebe e bolokoa sebakeng se pholileng, se omileng.
Ka mehato ena, glacial acetic acid e ka hlahisoa. Ho bohlokoa ho laola mocheso oa karabelo, khatello le mahloriso a li-catalyst tse fapaneng nakong eohle ea tlhahiso ho netefatsa tsoelo-pele ea karabelo e boreleli le boleng bo tsitsitseng ba sehlahisoa.
