Isingeniso
I-5-Fluoro-2-nitrotoluene iyinhlanganisela yezinto eziphilayo. Okulandelayo yisingeniso sezakhiwo zayo, ukusetshenziswa kwayo, izindlela zokukhiqiza kanye nolwazi lokuphepha:
Ikhwalithi:
- Ukubukeka: I-5-fluoro-2-nitrotoluene iyikristalu engenambala noma ephuzi.
- Izakhiwo zamakhemikhali: I-5-fluoro-2-nitrotoluene inokusimama okuhle kwamakhemikhali futhi akulula ukuguquguquka.
Sebenzisa:
- I-Chemical intermediate: I-5-fluoro-2-nitrotoluene ingasetshenziswa njengendawo ephakathi ku-organic synthesis yokuhlanganiswa kwamanye ama-organic compounds.
Indlela:
I-5-Fluoro-2-nitrotoluene ingahlanganiswa:
Ngaphansi kwezimo ze-alkaline, i-2-chlorotoluene yasabela nge-hydrogen fluoride ukuze kutholwe i-5-fluoro-2-chlorotoluene, yase isabela nge-nitric acid ukuze kutholwe umkhiqizo ohlosiwe ongu-5-fluoro-2-nitrotoluene.
Lapho kukhona utshwala, i-2-nitrotoluene isabela nge-hydrogen bromide, bese isabela nge-hydrogen fluoride, futhi ekugcineni umkhiqizo ulungiselelwa ukuphelelwa amanzi emzimbeni.
Ulwazi Lokuphepha:
- I-5-Fluoro-2-nitrotoluene ikhemikhali enokhahlo esikhumbeni nasemehlweni, ngakho gqoka amagilavu okuzivikela kanye nezibuko ukuze ugweme ukuthintana ngqo.
- Kufanele kuqashelwe izinyathelo zokuvimbela umlilo nokuqhuma ngesikhathi sokusetshenziswa nokuphathwa, futhi ugweme ukuthintana namalangabi avulekile, amazinga okushisa aphezulu noma eminye imithombo yomlilo.
- Sicela ugcine futhi uthuthe ngendlela efanele, kude nama-oxidants nezinto ezivuthayo.
- Uma ukumunca noma ukuhogela, funa usizo lwezokwelapha ngokushesha futhi unikeze ulwazi mayelana nekhemikhali.
