Selelekela

Ke motsoako oa tlhaho o nang le foromo ea lik'hemik'hale C7H5FN2. E latelang ke tlhaloso ea sebopeho sa eona, ts'ebeliso, tokiso le tlhaiso-leseling ea polokeho:

 

Tlhaho:

-Ponahalo: Ha e na mebala ho isa phofo e tšoeu ea kristale.

- Sebaka sa ho qhibiliha: hoo e ka bang likhato tse 84-88 tsa Celsius.

-Solubility: E qhibiliha ka har'a metsoako e mengata ea lintho tse phelang, tse kang ethanol, ether le dimethyl sulfoxide.

 

Sebelisa:

-e sebelisoa haholo-holo tšimong ea organic synthesis, e ka sebelisoa e le li-intermediates le lik'hemik'hale tsa lik'hemik'hale.

-E ka sebelisoa ho kopanya metsoako e meng ea manyolo, joalo ka lithethefatsi, chefo e bolaeang likokoanyana le dae.

 

Mokhoa oa ho itokisa:

Mokhoa oa ho lokisetsa ha o thata. E latelang ke mokhoa o tloaelehileng oa ho lokisa:

Karabelo ea 2-amino -4-chlorobenzonitrile le sodium fluoride tlas'a catalysis ea koporo chloride e hlahisoa. Maemo a karabelo hangata a etsoa ka ethyl acetate, hangata e hloka ho futhumatsa karabelo le mehato e nepahetseng ea ts'ebetso.

 

Lintlha tsa Tšireletseho:

-E na le ho hloka botsitso ho tlase tlas'a maemo a tloaelehileng a ho sebetsa. Leha ho le joalo, e le ntho ea lik'hemik'hale, ho ntse ho hlokahala ho latela mekhoa ea motheo ea ts'ireletso ea laboratori.

-Motsoako ona o ka koatisa mahlo le letlalo. Ho khothalletsoa ho roala liatlana tse sireletsang le likhalase tse loketseng nakong ea tšebeliso.

-Nakong ea polokelo le lipalangoang, qoba ho kopana le li-oxidants tse matla le li-acid tse matla ho thibela likotsi tse kotsi.

-Mehato ea thuso ea pele: Haeba u kopana le letlalo kapa mahlo, hlatsoa hang-hang ka metsi a mangata. Haeba o ka nooa kapa o hema, batla thuso ea bongaka hang-hang.
