Gusaba ibicuruzwa

Ahanini ikoreshwa muri synthesis ya metronidazole, dimetazole nibindi biyobyabwenge.

umusaruro

Biboneka na nitrasi ya 2-methylimidazole. Shira aside sulfurike, 2-methylimidazole na sodium sulfate mu nkono ya reaction, koga kandi ushushe, ongeramo aside nitric kuri 150-160 ℃, ongeraho, ukurikize isanduku yisaha kumasaha 1. Kuraho ubushyuhe kuri 140 ℃ munsi, nyuma yo kongeramo amazi namazi ya amoniya kugirango uhindure pH kuri 3.5-4, kristu. Shyira, ukarabe utabogamye, wumye, 2-methyl-5-nitroimidazole.

Ibisobanuro n'ububiko

25k igikapo cyimpapuro cyangwa igikapu (58 × 110) cyometseho umufuka wa pulasitike, umufuka wa kontineri 250 kg (100 × 80); Ukurikije ibyo umukiriya asabwa;
Ububiko bufunze, bubitswe mububiko bukonje, bwijimye, bwumye, kubika no gutwara bigomba kuba byoroshye, kugirango birinde kwangirika nubushuhe, bibujijwe rwose nibiyobyabwenge bivanze.

Uburyo bwo kubyaza umusaruro: Kubona nitrasi ya 2-methylimidazole. Shira aside sulfurike, 2-methylimidazole na sodium sulfate mu nkono ya reaction, koga kandi ushushe, ongeramo aside nitric kuri 150-160 ℃, ongeraho, ukurikize isanduku yisaha kumasaha 1. Kuraho ubushyuhe kuri 140 ℃ munsi, nyuma yo kongeramo amazi namazi ya amoniya kugirango uhindure pH kuri 3.5-4, kristu. Shyira, kwoza utabogamye, wumye, 2-methyl-5-nitroimidazole.
