Kenyelletso e khutšoanyane
4-Chloro-2-fluorobenzoic acid ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa thepa ea eona, tšebeliso, mekhoa ea tlhahiso le tlhaiso-leseling ea polokeho:
Boleng:
4-Chloro-2-fluorobenzoic acid ke kristale e tiileng, hangata e se nang 'mala kapa e mosehla. Ha e fetohe mocheso oa kamore. E na le tatso e nkhang hamonate 'me e ka qhibiliha ka har'a metsoako ea lintho tse phelang tse kang methanol, ethanol, methylene chloride, joalo-joalo.
Sebelisa:
4-Chloro-2-fluorobenzoic acid e na le mefuta e mengata ea lisebelisoa ho indasteri ea lik'hemik'hale. Hangata e sebelisoa e le thepa ea ho qala kapa e bohareng ba organic synthesis. E ka boela ea sebelisoa e le phepelo ea li-catalysts le lisebelisoa tsa elektroniki.
Mokhoa:
4-Chloro-2-fluorobenzoic acid e ka fumanoa ka chlorination ea p-fluorobenzoic acid. Ka kakaretso, hydrogen chloride kapa chlorous acid e ka itšoara ka thionyl chloride kapa sulfinyl chloride tlas'a maemo a acidic, e lateloa ke ho itšoara ka hydrogen fluoride ho fumana 4-chloro-2-fluorobenzoic acid.
Lintlha tsa Tšireletseho:
Mehato e latelang ea tšireletso e lokela ho nkoa ha u tšoara 4-chloro-2-fluorobenzoic acid: qoba ho kopana le letlalo le mahlo, 'me u ele hloko mehato ea tšireletso e kang ho roala likhalase tse sireletsang le liatlana. E lokela ho etsoa sebakeng se nang le moea o motle ho thibela ho hema kapa ho metsa. Qoba ho kopana le lintho tse tukang 'me u ipolokele hole le malakabe a bulehileng kapa mocheso o phahameng. E tlameha ho tiisoa ka thata ha e sebelisoa kapa e bolokoa le hole le li-acids, bases le li-oxidants. Ha ho e-na le ho lutla, mehato e loketseng ea tšohanyetso e lokela ho nkoa, e kang ho monya metsi ka desiccant kapa ho e hloekisa ka adsorbent e loketseng ea lik'hemik'hale.
