Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Amakhodi Engozi R24/25 -
I-R33 – Ingozi yemiphumela eqoqwayo
R38 – Ukucasuka esikhunjeni
R41 – Ingozi yokulimala okubi emehlweni
R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba.
R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile.
Incazelo Yokuphepha S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha.
S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu ​​kanye nokuvikela iso/ubuso.
S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.)
S36 – Gqoka izingubo ezifanele zokuzivikela.

Isingeniso

I-4-Trifluoromethoxyaniline iyinhlanganisela yezinto eziphilayo. Okulandelayo isingeniso esifushane sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:

 

Ikhwalithi:

- Ukubukeka: Uketshezi olungenambala

- Iphunga: Iphunga le-ammonia eliwuphawu

- Ukunyibilika: Kuncibilika kuzincibilikisi zemvelo ezifana notshwala, ama-ether nama-ketone

 

Sebenzisa:

- I-4-Trifluoromethoxyaniline ingasetshenziswa njengendawo emaphakathi ku-organic synthesis futhi ivamise ukusetshenziswa njenge-reagent ye-fluorinating ekuphenduleni kwe-organic synthesis, njengasekuhlanganiseni kwama-catalyst ekuphenduleni kwe-Suzuki.

 

Indlela:

- Indlela yokulungiselela ye-4-trifluoromethoxyaniline ivamise ukusebenzisa ukusabela kwe-amination. Umkhiqizo ungatholwa ngokusabela kwe-aniline nge-trifluoromethanol.

 

Ulwazi Lokuphepha:

- 4-Trifluoromethoxyaniline: Kufanele kuqashelwe ukugwema ukuthintana nesikhumba namehlo, futhi ugweme ukuhogela noma ukukungenisa.

- Uma usebenzisa futhi ugcina, ukuthintana nezinto ezifana nama-oxidants, ama-asidi aqinile, izisekelo eziqinile, ne-hydrogen oxide kufanele kugwenywe ukuze kugwenywe ukusabela okuyingozi.

- Landela ukugcinwa kwamakhemikhali kanye nemithetho yokuphatha futhi ugweme umlilo nokushisa.
