3,5-Dimethyl-4-nitrobenzoic acid(CAS#3095-38-3)
| Amakhodi Engozi | 36/37/38 - Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S36 – Gqoka izingubo ezifanele zokuzivikela. |
Isingeniso
I-4-Nitro-3,5-dimethylbenzoic acid iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
- I-4-Nitro-3,5-dimethylbenzoic acid iyikristale engenambala eqinile enambitheka enamakha.
- Azinzile ezingeni lokushisa legumbi, kodwa ukuqhuma kungase kwenzeke emazingeni okushisa aphezulu, ekukhanyeni, noma lapho kuvezwe emithonjeni yokuthungela.
- Cishe ayincibiliki emanzini, kodwa incibilika kuzincibilikisi zemvelo njenge-ethanol, ama-ether, nama-hydrocarbon ane-chlorine.
Sebenzisa:
- I-4-nitro-3,5-dimethylbenzoic acid isetshenziswa ikakhulukazi njengendawo ephakathi yamadayi kanye nempahla eluhlaza yokuhlanganiswa kwezingulube.
Indlela:
- I-4-Nitro-3,5-dimethylbenzoic acid ingatholakala ngokufaka i-nitrification ye-p-toluene. Ukusabela kwe-nitrification ngokuvamile kusebenzisa ingxube ye-nitric acid ne-sulfuric acid njenge-ejenti ene-nitrifying.
- Indlela ethile yokulungiselela ngokuvamile ithi: i-toluene ixubene ne-nitric acid ne-sulfuric acid, ishisiswe ukuze iphendule, bese icwecwe futhi ihlanzwe.
Ulwazi Lokuphepha:
- I-4-Nitro-3,5-dimethylbenzoic acid iyacasula futhi iyagqwala futhi kufanele igwenywe ukuthintana nesikhumba namehlo.
- Lapho uphatha lesi sithako, gqoka amagilavu okuzivikela, ama-respirators, nezibuko zokuzivikela ukuze ugweme ukuhogela amagesi noma ukuthintana nesikhumba.
- Lapho ugcina futhi uphatha, gwema ukuthintana nama-oxidants, imithombo yokushisa nezinto ezivuthayo ukuze ugweme umlilo noma ukuqhuma.
- Uma ungenwa ngephutha noma uhogele umoya, funa usizo lwezokwelapha ngokushesha futhi wethule ishidi ledatha yokuphepha komkhiqizo kudokotela wakho.
