Ikakhulukazi esetshenziswa synthesis metronidazole, dimetazole kanye nezinye izidakamizwa intermediates.
Itholakala nge-nitrate ye-2-methylimidazole.Faka i-sulfuric acid, i-2-methylimidazole ne-sodium sulfate ebhodweni lokusabela, gudluza futhi ushise, engeza i-nitric acid ku-150-160 ℃, hlanganisa, landela ukusabela kwe-casket ihora elingu-1.Susa izinga lokushisa libe ngu-140℃ ngezansi, ngemva kokwengeza amanzi anamanzi ammonia ukuze ulungise i-pH ibe ngu-3.5-4, icrystallization.Hlunga, geza ukuze ungathathi hlangothi, wome, 2-methyl-5-nitroimidazole.
Isikhwama sephepha esingu-25k se-kraft noma isikhwama esilukiwe (58×110) esifakwe isikhwama sepulasitiki, isikhwama sesitsha sokuthekelisa esingu-250kg (100×80);Ngokwezidingo zamakhasimende;
Isitoreji esivaliwe, esigcinwe endaweni epholile, emnyama, eyomile, isitoreji kanye nezinto zokuhamba kufanele kube lula, ukuvimbela umonakalo nomswakama, kuvinjelwe ngokuqinile nezidakamizwa ezixutshwe.
Indlela yokukhiqiza: Itholwe nge-nitrate ye-2-methylimidazole.Faka i-sulfuric acid, i-2-methylimidazole ne-sodium sulfate ebhodweni lokusabela, gqugquzela futhi ushise, engeza i-nitric acid ku-150-160 ℃, hlanganisa, landela ukusabela kwe-casket ihora elingu-1.Susa izinga lokushisa libe ngu-140℃ ngezansi, ngemva kokungeza amanzi anamanzi ammonia ukuze ulungise i-pH ibe ngu-3.5-4, i-crystallization.Hlunga, geza ukuze ungathathi hlangothi, wome, 2-methyl-5-nitroimidazole.
