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

Sebenzisa I-4-methoxyphenylhydrazine hydrochloride iphakathi, ikakhulukazi esetshenziselwa ukukhiqiza ama-phenylhydrazine compounds, futhi ingasetshenziselwa ukukhiqiza eminye imikhiqizo yamakhemikhali, njenge-4-nitroindole ne-apixaban.
Kusetshenziswa odayi nabaphakathi kwezemithi
Ukulungiselela I-4-methoxyphenylhydrazine hydrochloride ingalungiswa kusuka ku-aniline ngokusabela kwe-diazotization.
Thatha i-aniline, i-hydrochloric acid ne-sodium nitrite, isilinganiso se-molar phakathi kwakho ngu-1: 3.2: 1.0, qala ungeze i-hydrochloric acid, bese ufaka i-ammonium nitrite ku-5 ℃, bese usabela ku-0 ~ 20 ℃ imizuzu engu-40 ukuze ukhiqize i-diazobenzene e-chlorine; Ngokwesilinganiso se-molar ye-aniline kuya ku-1: 3.5: 2.5, i-ammonium sulfite ne-hydrochloric acid yengezwa, futhi ukunciphisa, i-hydrolysis ne-acidification yenziwa kugedlela lokunciphisa, isikhathi sokunciphisa imizuzu engama-60 ~ 70, kanye ne-hydrolysis ne-acidification. isikhathi imizuzu engama-50. Okokuqala, i-ammonium sulfite isabela nge-hydrochloric acid eyeqile ukukhiqiza i-ammonium bisulfite, i-ammonium bisulfite, i-ammonium sulfite ihlangana ne-chlorinated diazobenzene ukwenza i-phenylhydrazine disulfonate, bese isabela nge-hydrochloric acid yokuhlaziywa kwe-hydrolysis kanye ne-asidi Ukusabela, futhi ngemva kokumisa i-spin-drying, 4. I-methoxyphenylhydrazine hydrochloride iyalungiswa.
