4-Methoxyphenylhydrazine hydrochloride (CAS# 19501-58-7) Zambiri

Gwiritsani ntchito 4-methoxyphenylhydrazine hydrochloride ndi yapakatikati, yomwe imagwiritsidwa ntchito makamaka popanga mankhwala a phenylhydrazine, komanso ingagwiritsidwe ntchito popanga mankhwala ena, monga 4-nitroindole ndi apixaban.
Amagwiritsidwa ntchito pa utoto ndi mankhwala apakatikati
Kukonzekera 4-methoxyphenylhydrazine hydrochloride ikhoza kukonzedwa kuchokera ku aniline kudzera mu diazotization reaction.
Tengani aniline, hydrochloric acid ndi sodium nitrite, chiŵerengero cha molar pakati pawo ndi 1: 3.2: 1.0, choyamba onjezerani hydrochloric acid, kenaka yikani ammonium nitrite pa 5 ℃, ndikuchitapo pa 0 ~ 20 ℃ kwa mphindi 40 kuti mupange chlorinated diazobenzene; Malingana ndi chiŵerengero cha molar cha aniline ku 1: 3.5: 2.5, ammonium sulfite ndi hydrochloric acid amawonjezedwa, ndipo kuchepetsa, hydrolysis ndi acidification ikuchitika mu ketulo yochepetsera, nthawi yochepetsera ndi mphindi 60-70, ndi hydrolysis ndi acidification. nthawi ndi mphindi 50. Choyamba, ammonium sulfite amachitira ndi owonjezera hydrochloric asidi kupanga ammonium bisulfite, ammonium bisulfite, ammonium sulfite amachitira ndi chlorinated diazobenzene kupanga phenylhydrazine disulfonate, ndiyeno amachitira ndi hydrochloric asidi kwa hydrolysis ndi asidi kusanthula The anachita, ndipo pambuyo sapota-kuyanika, 4. Methoxyphenylhydrazine hydrochloride imakonzedwa.
