Mas siv nyob rau hauv cov synthesis ntawm metrefes, dimetazole thiab lwm yam tshuaj nruab nrab.
Nws yog tau los ntawm nevort ntawm 2-mutterslimidazole. Muab cov sulfuric acid, 2-mthenylimidazole thiab sodium sulfate rau hauv cov tshuaj tiv thaiv lauj kaub, ntxiv rau, ua raws li cov tshuaj tiv thaiv ua raws li 1 teev. Tshem tawm qhov kub txog 140 ℃ hauv qab no, tom qab ntxiv dej nrog dej ammonia los kho cov p rau 3.5-4, crystallization. Lim, ntxuav mus rau nruab nrab, qhuav, 2-methyl-5-nitroimidazole.
25k kraft daim ntawv hnab los yog Woven Hnab (58 × 110) ib lub hnab yas, 250kg export thawv hnab (100 × 80); Raws li cov neeg siv khoom;
Kaw cia, khaws cia rau hauv qhov chaw txias, tsaus, qhuav thiab kev thauj mus los yuav tsum yog lub teeb, kom tiv thaiv kev puas tsuaj thiab noo noo txwv tsis pub siv yeeb tshuaj sib xyaw.
Txujci Ntau Lawm: Tau los ntawm Nitration ntawm 2-Metylimidazole. Muab cov sulfuric acid, 2-mthenylimidazole thiab sodium sulfate rau hauv cov tshuaj tiv thaiv lauj kaub, ntxiv rau, ua raws li cov tshuaj tiv thaiv ua raws li 1 teev. Tshem tawm qhov kub txog 140 ℃ hauv qab no, tom qab ntxiv dej nrog dej ammonia los kho cov p rau 3.5-4, crystallization. Lim, ntxuav mus rau nruab nrab, qhuav, 2-methyl-5-nitroimidazole.
