3, ke motsoako oa manyolo o nang le foromo ea lik'hemik'hale C6H6Cl2N2. E latelang ke tlhaloso ea sebopeho sa eona, tšebeliso, tlhahiso le tlhaiso-leseling ea polokeho:

 

Tlhaho:

-Ponahalo: 3, ha e na 'mala ho isa ho kristale e mosehla kapa phofo.

-Solubility: E ka qhibiliha ka har'a metsi le metsoako ea tlhaho.

- Sebaka sa ho qhibiliha: Sebaka sa eona se qhibilihisang ke 70-72 ° C.

-Botsitso: E tsitsitse mocheso oa kamore, empa e ka 'na ea bola ka mocheso o phahameng.

 

Sebelisa:

- 3, eo hangata e sebelisoang e le karolo e bohareng ea organic synthesis, e ka sebelisoa ho kopanya metsoako le ts'ebetso ea tlhaho.

-E ka boela ea sebelisoa lipatlisisong tsa lithethefatsi, tlhahiso ea chefo e bolaeang likokoanyana le mafapheng a mang.

 

Mokhoa:

-Motsoako oa isocyanate o ka itšoara ka 2-amino -3, 5-dichloro-6-methylbenzaldehyde ho hlahisa 3 pyridine.

 

Lintlha tsa Tšireletseho:

- 3, chefo e tlaase, empa e ntse e lokela ho ela hloko mehato ea tšireletso, ho qoba ho kopana le letlalo, mahlo le ho hema lerōle la eona.

-Apara lisebelisoa tsa ts'ireletso tse nepahetseng joalo ka liatlana tsa lab, likhalase tsa tšireletso le limaske tse sireletsang nakong ea ts'ebeliso le ts'ebetso.

-Ha e a tlameha ho lokollwa tikolohong.

-Ha u e boloka, e boloke ka sejaneng se tiisitsoeng, hole le mollo le li-oxidizing agents.

-Haeba o koetsoe kapa o hema, batla thuso ea bongaka hang-hang.
