3-Fluoro-4-nitrotoluene (CAS# 446-34-4)
| Amakhodi Engozi | R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile. R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. I-S36/37 – Gqoka izingubo zokuzivikela ezifanele namagilavu. S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) S37 – Gqoka amagilavu afanelekile. I-S28A - I-S24/25 - Gwema ukuthintana nesikhumba namehlo. |

Isingeniso
I-3-Fluoro-4-nitrotoluene iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo, ukusetshenziswa, izindlela zokulungiselela kanye nolwazi lokuphepha lwale nhlanganisela:
Ikhwalithi:
I-3-fluoro-4-nitrotoluene iyikristalu engenambala eqinile enephunga le-benzene. Isisindo sayo samangqamuzana singu-182.13 g/mol. Inhlanganisela inokuncibilika okuphansi futhi incibilika kuzincibilikisi zemvelo njenge-ethanol ne-ether.
Sebenzisa:
I-3-fluoro-4-nitrotoluene isetshenziselwa kakhulu ukusabela kwe-fluorination ku-organic synthesis. Ingasetshenziswa futhi kumadayi, ama-organic coatings, izinto ezibonakalayo, njll.
Indlela:
I-3-fluoro-4-nitrotoluene ilungiswa ngezindlela ezihlukahlukene, futhi indlela yakudala itholakala nge-fluorination ye-cyanonitrobenzene. Inqubo ethile yokulungiselela iyinkimbinkimbi futhi idinga izimo nezindlela zaselabhorethri zamakhemikhali.
Ulwazi Lokuphepha:
I-3-fluoro-4-nitrotoluene iyinhlanganisela enobuthi. Ngesikhathi sokuhlinzwa, ukunakekelwa kufanele kuthathwe ukuze kugwenywe ukuthintana nesikhumba namehlo, futhi umoya owanele kufanele kwenziwe. Uma uhogele umoya noma udliwe, funa usizo lwezokwelapha ngokushesha. Ngesikhathi sokugcina, ukuthintana nezinto ezivuthayo, ama-oxidants, njll. kufanele kugwenywe, futhi kugcinwe endaweni epholile, eyomile. Kudingeka ukuthobela ngokuqinile imithetho nemithethonqubo efanele futhi uphathe kahle futhi ulahle imfucuza. Uma usebenzisa noma uphatha, sicela ubheke futhi ulandele izinqubo ezifanele zokusebenza zokuphepha.
