2-Bromo-4-methylbenzonitrile (CAS# 42872-73-1)
| Amakhodi Engozi | R20/21/22 – Kuyingozi ngokuhogela umoya, ukuthintana nesikhumba futhi uma ukugwinyile. R36/37/38 – Ukucasula amehlo, uhlelo lokuphefumula kanye nesikhumba. I-R22 – Iyingozi uma igwinywe |
| Incazelo Yokuphepha | S26 – Uma uthintana namehlo, geza ngokushesha ngamanzi amaningi futhi ufune iseluleko sezokwelapha. S36/37/39 – Gqoka izingubo zokuzivikela ezifanele, amagilavu kanye nokuvikela iso/ubuso. |
| Ama-ID e-UN | 3439 |
| I-WGK Germany | 3 |
| I-Hazard Class | I-IRRITANT, IRRITANT-H |
Isingeniso
Kuyinhlanganisela ye-organic ifomula yayo yamakhemikhali i-C8H6BrN. Okulandelayo yincazelo yemvelo yayo, ukusetshenziswa, ukwakhiwa kanye nolwazi lokuphepha:
Imvelo:
-Ukubukeka: Ayinambala ikristale ephuzi
-Indawo yokuncibilika: 64-68 degrees Celsius
-Indawo yokubilisa: 294-296 degrees Celsius
-Ukuminyana: 1.51 g/ml
-Ukunyibilika: Kuncibilika kancane emanzini, kuncibilika kuzincibilikisi ezivamile ezifana ne-ethanol, i-ether ne-benzene
Sebenzisa:
Ivamise ukusetshenziswa njengendawo ephakathi ku-organic synthesis futhi ingasetshenziswa ukulungisa ezinye izinhlanganisela eziphilayo. Ingasetshenziswa ekuhlanganiseni kwemithi, ekuhlanganiseni kwezibulala-zinambuzane, nasezimbonini zikadayi nezokupenda.
Indlela Yokulungiselela: Ukulungiswa kwe
ngokuvamile kwenziwa yizinyathelo ezilandelayo:
1. Phendula i-p-methylbenzonitrile nge-bromine ngaphansi kwezimo zokusabela ezifanele ukuze ukhiqize i-phenol.
Ulwazi Lokuphepha:
-iyinhlanganisela engaba khona yezinto eziphilayo futhi kufanele isingathwe ngokuqapha.
-Ngesikhathi sokusebenza, ukunakekelwa kufanele kuthathwe ukugwema ukuthintana ngqo nesikhumba, amehlo kanye nomgudu wokuphefumula.
-Gqoka izinto zokuzivikela ezifanele, njengamagilavu zelabhu nezibuko.
-Kufanele isetshenziswe endaweni engenawo umoya futhi igweme ukuhogela umhwamuko noma uthuli.
-Uma uhogelwe noma udliwe ngephutha, funa usizo lwezokwelapha ngokushesha futhi ubonise isiqukathi noma ilebula ukuze uthole ireferensi.
Sicela uqaphele ukuthi noma yiziphi izinto zamakhemikhali kufanele zisetshenziswe ngaphansi kwezimo ezifanele zaselabhorethri futhi zilandele izinqubo ezifanele zokusebenza eziphephile.
