Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Izimpawu Eziyingozi T – Inobuthi
Amakhodi Engozi R23/24/25 – Kunobuthi ngokuhogela, ukuthintana nesikhumba futhi uma ugwinywe.
I-R33 – Ingozi yemiphumela eqoqwayo
Incazelo Yokuphepha I-S37 – Gqoka amagilavu ​​afanelekile.
S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.)

 

Isingeniso

I-1-Bromo-3-nitrobenzene iyinhlanganisela ye-organic enefomula yamakhemikhali ethi C6H4BrNO2. Okulandelayo incazelo yezinye izakhiwo zayo, ukusetshenziswa, izindlela kanye nolwazi lokuphepha:

 

Imvelo:

I-1-Bromo-3-nitrobenzene iyikristalu engenambala noma i-crystalline powder ephuzi ephuzi enephunga elikhethekile. Ayincibiliki emanzini futhi iyancibilika kuma-organic solvents.

 

Sebenzisa:

I-1-Bromo-3-nitrobenzene iyingxenye ebalulekile ye-organic synthesis, engasetshenziswa ukuhlanganisa izidakamizwa ezihlukahlukene, odayi kanye nezibulala-zinambuzane. Ingasetshenziswa futhi njenge-reagent kanye ne-catalyst yokusabela kwamakhemikhali.

 

Indlela Yokulungiselela:

I-1-Bromo-3-nitrobenzene ingahlanganiswa nge-bromination ye-nitrobenzene. I-Bromine ne-sulfuric acid ngokuvamile zisetshenziselwa ukusabela ukwenza i-brominating agent, esabela nge-nitrobenzene ukunikeza i-1-Bromo-3-nitrobenzene.

 

Ulwazi Lokuphepha:

I-1-Bromo-3-nitrobenzene iyingozi emzimbeni womuntu nendawo. Kuyinto evuthayo futhi idinga ukugcinwa kude namalangabi avulekile kanye namazinga okushisa aphezulu. Ukuthinta isikhumba noma ukuhogela umhwamuko waso kungase kubangele ukucasuka nokulimala. Gqoka amagilavu ​​okuzivikela kanye nezibuko ngesikhathi sokuphatha nokusebenzisa, futhi uqinisekise ukungena komoya okuhle. Uma igcinwe, kufanele igcinwe endaweni eyomile, epholile futhi kude nama-oxidants nama-asidi. Endabeni yokuchitheka kwengozi, kufanele kuthathwe izinyathelo ezifanele ukubhekana nakho nokuhlanza. Ngaphambi kokusetshenziswa, kunconywa ukuthi ubhekisele kumanuwali okusebenza ngokuphepha afanele kanye neshidi ledatha yokuphepha.
