Selelekela

2,6-Dichloro-4-trifluoromethylaniline, eo hape e tsejoang e le DCPA, ke motsoako oa lintho tse phelang. Se latelang ke selelekela sa sebopeho, tšebeliso, mokhoa oa tlhahiso le tlhaiso-leseling ea polokeho ea DCPA:

 

Boleng:

- Ha e na 'mala ho isa ho likristale tse mosehla kapa lintho tse thata tse entsoeng ka phofo.

- DCPA e na le ho hloka botsitso ho tlase mocheso oa kamore.

- Ha e qhibilihe ka metsing 'me e batla e qhibiliha ka har'a metsoako ea tlhaho.

 

Sebelisa:

- DCPA e atisa ho sebelisoa e le thepa e tala le e bohareng bakeng sa chefo e bolaeang likokoanyana.

- E sebelisoa haholo temong ho laola lehola, li-fungus, likokoanyana le mafu a fapaneng.

- DCPA e ka boela ea sebelisoa e le setsi sa polokelo ea metsi ho ntlafatsa tlhahiso ea seliba le ho lelefatsa bophelo ba bophelo.

 

Mokhoa:

- Ho na le mekhoa e mengata ea ho itokisa bakeng sa DCPA, e ka hlahisoang ke karabelo ea aniline le trifluorocarboxic acid.

- Qhala aniline ka har'a motsoako oa joala 'me butle-butle eketsa trifluoroformic acid.

- Hangata mocheso oa karabelo o laoloa ka tlase ho -20 ° C, 'me nako ea ho arabela e telele.

- Qetellong ea karabelo, DCPA e fumanoa ka ho omisa le ho hloekisa sehlahisoa.

 

Lintlha tsa Tšireletseho:

- DCPA e nkoa e le motsoako o tlaase oa chefo tlas'a maemo a tloaelehileng.

- Leha ho le joalo, tlhokomelo e ntse e lokela ho nkoa ho e sebelisa le ho e boloka ka bohlale, le ho qoba ho kopana le letlalo, mahlo le tsela ea ho hema.

- Liatlana tse sireletsang, mese, le lisebelisoa tsa ho itšireletsa li lokela ho apesoa nakong ea ts'ebeliso.
