Selelekela

Ke motsoako oa tlhaho o nang le foromo C6H5ClFN. Ke mokelikeli o se nang 'mala o nang le monko o khethehileng. E latelang ke tlhaloso ea sebopeho sa eona, ts'ebeliso, tokiso le tlhaiso-leseling ea polokeho:

 

Tlhaho:

-Ponahalo: mokelikeli o se nang 'mala

-Monko: Monko o khethehileng

- Boima ba 'mele: 1.36 g/mL

Sebaka se belang: 137-139 ℃

-Ntho e qhibilihang:-4 ℃

-Solubility: E kopane le metsoako ea tlhaho, e batlang e sa qhibilihe metsing.

 

Sebelisa:

E sebelisoa haholo ho organic synthesis mme e ka sebelisoa e le mokelikeli kapa thepa e tala. E na le ts'ebeliso ea bohlokoa ts'ebetsong ea chefo e bolaeang likokoanyana, meriana le lik'hemik'hale, 'me hangata e sebelisoa ha ho etsoa chefo e bolaeang likokoanyana, dae, solvents, joalo-joalo.

 

Mokhoa oa ho itokisa: Mokhoa oa ho lokisetsa oa

e rarahane ho feta. Mokhoa o akaretsang oa ho itokisa ke ho fumana 5-chloro -2-oxo -3-methyl pyridine ka chloro-propionaldehyde reaction ka pyridine e le thepa e tala, le ho fumana sehlahisoa sa ho qetela ka karabelo ea fluorination.

 

Lintlha tsa Tšireletseho:

Ke motsoako oa lintho tse phelang, 'me mehato e latelang ea tšireletso e lokela ho eloa hloko ha u e sebelisa:

-Toxicity e ka bakoa ke ho hema, ho kopana kapa ho noa. Ho kopana ka ho toba le letlalo, mahlo le lera la mucous le lokela ho qojoa.

-Apara lisebelisoa tse nepahetseng tsa ts'ireletso joalo ka liatlana, likhalase le liaparo tsa tšireletso ha u sebelisoa.

- Qoba ho kopana le li-oxidants, li-acid tse matla, li-bases tse matla le lintho tse ling ho qoba liketso tse sa sireletsehang.

-Ha ho lutla ho etsahala, mehato e nepahetseng e lokela ho nkoa ho hloekisa metsi le ho qoba ho kena tsamaisong ea metsi le tikoloho.

 

Ha u sebelisa motsoako, nka mehato e ts'oanang ea ts'ireletso ho ea ka boemo ba sebele 'me u bue ka letlapa la tšireletso la motsoako.
