4-Fluoro-3-nitrotoluene (CAS# 446-11-7)
| Amakhodi Engozi | R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile. R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. R34 – Ibangela ukusha |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S36 – Gqoka izingubo ezifanele zokuzivikela. S45 – Uma kwenzeka ingozi noma uzizwa ungaphilile, funa iseluleko sezokwelapha ngokushesha (bonisa ilebula noma nini lapho kunokwenzeka.) S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. |
| Inothi Lengozi | Iyacasula |
| I-Hazard Class | 6.1 |
Isingeniso
I-4-Fluoro-3-nitrotoluene iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sobunjalo bayo, ukusetshenziswa, indlela yokulungiselela kanye nolwazi lokuphepha:
Ikhwalithi:
I-4-Fluoro-3-nitrotoluene iyikristale eqinile engenambala futhi ezinzile ekamelweni lokushisa. Incibilika kalula kuzincibilikisi eziphilayo njenge-ethanol, i-chloroform, ne-dimethylformamide.
Sebenzisa:
I-4-fluoro-3-nitrotoluene ivamise ukusetshenziswa njengento yokuqala noma emaphakathi ekuphenduleni kwe-organic synthesis. Ngaphezu kwalokho, ingasetshenziswa futhi njengempahla eluhlaza yama-fungicides nama-insecticides.
Indlela:
I-4-Fluoro-3-nitrotoluene ingahlanganiswa ngezindlela ezihlukahlukene. Indlela evamile ukwethula amaqembu e-fluorine nawe-nitro abe yi-toluene. Lokhu kusabela ngokuvamile kusebenzisa i-hydrogen fluoride ne-nitric acid njengama-reagents okusabela, futhi izimo zokusabela zidinga ukulawulwa kahle.
Ulwazi Lokuphepha:
Uma usebenzisa i-4-fluoro-3-nitrotoluene, lezi zinyathelo zokuphepha ezilandelayo kufanele ziqashelwe:
Kuyikhemikhali enomphumela ocasulayo emehlweni, esikhumbeni, nasemgudwini wokuphefumula futhi kufanele kugwenywe.
Izinto zokuzivikela ezinjengamagilavu, izibuko zokuzivikela, nezingubo zokuzivikela kufanele zisetshenziswe lapho usebenza.
Kufanele isetshenziswe endaweni enomoya omuhle ukugwema ukuhogela umhwamuko wayo.
Zama ukugwema ukuthintana nama-oxidants, ama-asidi aqinile, noma izisekelo eziqinile ukuze uvimbele ukusabela okuyingozi.
