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

Sebenzisa I-4-methoxyphenylhydrazine hydrochloride yindawo ephakathi, eyona nto isetyenziselwa ukuvelisa i-phenylhydrazine compounds, kwaye ingasetyenziselwa ukuvelisa ezinye iimveliso zeekhemikhali, ezifana ne-4-nitroindole kunye ne-apixaban.
Isetyenziswa kwiidayi kunye neziphakathi zamayeza
Ukulungiselela I-4-methoxyphenylhydrazine hydrochloride inokulungiswa ukusuka kwi-aniline nge-diazotization reaction.
Thatha i-aniline, i-hydrochloric acid kunye ne-nitrite ye-sodium, umlinganiselo we-molar phakathi kwabo ngu-1: 3.2: 1.0, okokuqala ungeze i-hydrochloric acid, uze ungeze i-ammonium nitrite kwi-5 ℃, kwaye uphendule kwi-0 ~ 20 ℃ imizuzu engama-40 ukuvelisa i-diazobenzene e-chlorine; Ngokwe-molar ratio ye-aniline ukuya ku-1: 3.5: 2.5, i-ammonium sulfite kunye ne-hydrochloric acid yongezwa, kwaye ukunciphisa, i-hydrolysis kunye ne-acidification yenziwa kwi-kettle yokunciphisa, ixesha lokunciphisa yimizuzu engama-60 ~ 70, kunye ne-hydrolysis kunye ne-acidification. ixesha yi 50 imizuzu. Okokuqala, i-ammonium sulfite isabela nge-acid engaphezulu kwe-hydrochloric ukuvelisa i-ammonium bisulfite, i-ammonium bisulfite, i-ammonium sulfite isabela ne-chlorinated diazobenzene ukwenza i-phenylhydrazine disulfonate, kwaye isabela nge-hydrochloric acid ye-hydrolysis kunye nohlalutyo lwe-asidi Ukusabela, kwaye emva kokumisa-ukumisa, 4 I-methoxyphenylhydrazine hydrochloride ilungisiwe.
