4-(methylamino)-3-nitrobenzoic acid (CAS# 41263-74-5)
| I-Hazard Class | I-IRRITANT |
Isingeniso
I-4-Methylamino-3-nitrobenzoic acid iyinhlanganisela ephilayo. Okulandelayo ulwazi mayelana nezakhiwo, ukusetshenziswa, izindlela zokulungiselela nokuphepha kwalesi sithako:
Ikhwalithi:
- I-4-Methylamino-3-nitrobenzoic acid iyikristalu engenambala noma ephuzi ngokukhanyayo enobhakha kanye nokunambitheka okubabayo.
- Inhlanganisela iyancibilika kancane emanzini futhi inyibilika ku-ethanol nezincibilikisi ze-ether.
Sebenzisa:
- Isetshenziswa kakhulu ekulungiseni amakhemikhali afana nodayi, izibulala-zinambuzane, neziqhumane.
Indlela:
- I-4-Methylamino-3-nitrobenzoic acid ingalungiswa nge-acylation ye-p-nitrobenzoic acid ne-toluidine.
- Ekuphenduleni, i-nitrobenzoic acid ne-toluidine kuqala yengezwa emkhunjini wokusabela, futhi ukusabela kushukunyiswa ezingeni lokushisa elifanele ukuze ekugcineni kutholwe umkhiqizo.
Ulwazi Lokuphepha:
- I-4-Methylamino-3-nitrobenzoic acid iyacasula futhi kufanele iphathwe ngokuqapha futhi izinto zokuzivikela kufanele zigqokwe.
- Kufanele kuqashelwe lapho uphatha inhlanganisela ukuze ugweme ukuthinta isikhumba namehlo, futhi ugweme ukuhogela uthuli noma umhwamuko waso.
- Gcina kude nemithombo yomlilo neyokushisa futhi ugcine iziqukathi zivaliwe.
- Ukuthobela izinqubo zokusebenza zokuphepha ezifanele ngesikhathi sokusetshenziswa. Izinyathelo zosizo lokuqala ezingenzeka kanye nezindlela zokulahla imfucuza.
- Uma uzwa noma yikuphi ukungakhululeki noma uhogele inani elikhulu lenhlanganisela, funa usizo lwezokwelapha ngokushesha.
