4-Methoxyphenylhydrazine hydrochloride（CAS# 19501-58-7) Faamatalaga
| Fa'aoga | 4-methoxyphenylhydrazine hydrochloride o se vaeluaga, e masani ona faʻaaogaina e gaosia ai le phenylhydrazine compound, ma e mafai foi ona faʻaaogaina e gaosia ai isi vailaʻau, e pei ole 4-nitroindole ma apixaban. Fa'aoga i vali ma vaila'au fa'alatalata |
| Sauniuniga | 4-methoxyphenylhydrazine hydrochloride e mafai ona saunia mai le aniline e ala i le diazotization reaction. Ave aniline, hydrochloric acid ma sodium nitrite, o le fua molar i le va oi latou o le 1: 3.2: 1.0, muamua faaopoopo hydrochloric acid, ona faaopoopo ai lea o le ammonium nitrite i le 5 ℃, ma tali atu i le 0 ~ 20 ℃ mo le 40 minute e gaosia ai le diazobenzene chlorinated; E tusa ai ma le fua faatatau molar o le aniline i le 1: 3.5: 2.5, o le ammonium sulfite ma le hydrochloric acid ua faʻaopoopoina, ma faʻaititia, hydrolysis ma acidification o loʻo faia i le faʻaitiitia o le ulo, o le taimi faʻaitiitia o le 60 ~ 70 minute, ma le faʻamaʻi ma le faʻasaʻo. o le taimi e 50 minute. Muamua, o le ammonium sulfite e tali atu i le sili atu o le hydrochloric acid e maua ai le ammonium bisulfite, ammonium bisulfite, ammonium sulfite e tali atu i le diazobenzene chlorinated e fausia ai le phenylhydrazine disulfonate, ona tali atu lea ma le hydrochloric acid mo le hydrolysis ma le su'esu'eina o le acid O le tali, ma a uma ona fa'amago, 4 methoxyphenylhydrazine hydrochloride ua saunia. |
