4-Methoxyphenylhydrazine hydrochloride (CAS# 19501-58-7) Information
| Shandisa | 4-methoxyphenylhydrazine hydrochloride inzvimbo yepakati, inonyanya kushandiswa kubudisa phenylhydrazine compounds, uye inogonawo kushandiswa kugadzira mamwe mishonga yemakemikari, yakadai se4-nitroindole uye apixaban. Inoshandiswa kune dhayi uye mishonga yepakati |
| Kugadzirira | 4-methoxyphenylhydrazine hydrochloride inogona kugadzirirwa kubva kune aniline kuburikidza nediazotization reaction. Tora aniline, hydrochloric acid uye sodium nitrite, iyo molar ratio pakati pavo ndeye 1: 3.2: 1.0, tanga wawedzera hydrochloric acid, wozowedzera ammonium nitrite pa5 ℃, uye ita pa 0 ~ 20 ℃ kwemaminitsi makumi mana kuti ibudise chlorinated diazobenzene; Zvinoenderana neiyo molar chiyero che aniline kusvika 1: 3.5: 2.5, ammonium sulfite uye hydrochloric acid inowedzerwa, uye kuderedza, hydrolysis uye acidification inoitwa mu kettle yekudzikisa, nguva yekudzikisa i60 ~ 70 maminetsi, uye iyo hydrolysis uye acidification. nguva maminitsi makumi mashanu. Chekutanga, ammonium sulfite inopindirana neyakawandisa hydrochloric acid kugadzira ammonium bisulfite, ammonium bisulfite, ammonium sulfite inopindirana nechlorinated diazobenzene kuumba phenylhydrazine disulfonate, uyezve inopindirana nehydrochloric acid yehydrolysis uye acid analysis The reaction, and after spin-drying, 4. Methoxyphenylhydrazine hydrochloride inogadzirwa. |
