Nzira:
Nzira yekugadzirira ye5-fluoro-2-nitrobenzoic acid inowanzowanikwa ne fluorination reaction ye 2-nitrobenzoic acid.
1. Kutanga, 2-nitrobenzoic acid inobatwa neine fluorinating agent (yakadai sehydrogen fluoride kana sodium fluoride).
2. Mushure mekuita, 5-fluoro-2-nitrobenzoic acid chigadzirwa chakawanikwa.
Izvo zvinofanirwa kucherechedzwa kuti panguva yekugadzirira maitiro, akakodzera ekuyedza mamiriro ekushanda uye matanho ekuchengetedza anofanirwa kushandiswa kuve nechokwadi chekuchengetedzwa kwekuyedza.
Zvekuchengetedza
- 5-fluoro-2-nitrobenzoic acid inoonekwa seyakachengetedzeka musanganiswa pasi pemamiriro ese, asi ichiri kuda kubatwa nemazvo uye kutevedzera maitiro akakodzera ekuedza.
-Mukubatana nekomboni iyi, kutarisana kweganda rakananga uye inhalation yeguruva rayo kunofanira kudziviswa.
-Mukushandiswa nekuchengetedza maitiro, ndapota chengetedza zvakanaka michina yerabhoritari, uye teererai neakakodzera mirairo yekuchengetedza.
-Pakaitika tsaona kana fungidziro yechepfu, tsvaga kurapwa nekukurumidza uye uuye nepepa rekuchengetedza data rekomboni.
