Selelekela

S-(-)-2-chloropropionic acid ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa thepa ea eona, tšebeliso, mekhoa ea tlhahiso le tlhaiso-leseling ea polokeho:

 

Thepa: S-(-)-2-chloropropionic acid ke mokelikeli o se nang 'mala o monko o monate. E qhibiliha metsing le ethanol 'me ha e qhibilihe ka har'a ether. Mocheso oa kamore, e na le khatello e itekanetseng ea mouoane.

 

Lisebelisoa: S-(-) -2-chloropropionic acid hangata e sebelisoa e le reagent, catalyst le intermediate in organic synthesis.

 

Mokhoa oa ho itokisa: Ho na le mekhoa e 'meli e meholo ea ho lokisa ea S-(-)-2-chloropropionic acid. Mokhoa o mong ke ho fumana letsoai la sodium la S-(-) -2-chloropropionate ka karabelo ea phenylsulfonyl chloride le sodium ethanol albutan, ebe o e etsa asiti ho theha sehlahisoa se lebisitsoeng. Mokgwa o mong ke wa ho hlwekisa ka hexanone le hydrogen chloride ka boteng ba oxidant, ebe ho latelwa ke acidification ho fumana sehlahiswa se lebisitsweng.

 

Tlhahisoleseding ka polokeho: S-(-)-2-chloropropionic acid e ea tena 'me e lokela ho qojoa ha e kopana le letlalo le mahlo. Lisebelisoa tse loketseng tsa tšireletso, tse kang liatlana le likhalase, li lokela ho apesoa ha li sebetsa. Boloka sebakeng se se nang moea, hole le mollo le li-oxidants.
