4-Methoxyphenylhydrazine hydrochloride (CAS# 19501-58-7) Macluumaadka
| Isticmaal | 4-methoxyphenylhydrazine hydrochloride waa dhexdhexaad, inta badan loo isticmaalo in lagu soo saaro xeryahooda phenylhydrazine, waxaana sidoo kale loo isticmaali karaa in lagu soo saaro walxo kale oo kiimiko ah, sida 4-nitroindole iyo apixaban. Lagu dabaqay dheeha iyo kuwa dhexdhexaadka ah ee dawooyinka |
| Diyaarinta | 4-methoxyphenylhydrazine hydrochloride waxaa laga diyaarin karaa aniline iyada oo loo marayo falcelinta diazotization. Qaado aniline, hydrochloric acid iyo sodium nitrite, saamiga molar ee u dhexeeya waa 1: 3.2: 1.0, marka hore ku dar hydrochloric acid, ka dibna ku dar ammonium nitrite at 5 ℃, oo ka falceliya 0 ~ 20 ℃ 40 daqiiqo si aad u dhaliso diazobenzene koloriin leh; Marka loo eego saamiga molar ee aniline ilaa 1: 3.5: 2.5, ammonium sulfite iyo hydrochloric acid ayaa lagu daraa, iyo hoos u dhigista, hydrolysis iyo acidification ayaa lagu sameeyaa kiliyaha dhimista, waqtiga dhimista waa 60 ~ 70 daqiiqo, iyo hydrolysis iyo acidification waqtigu waa 50 daqiiqo. Marka hore, ammonium sulfite waxay la falgashaa hydrochloric acid xad-dhaaf ah si ay u soo saarto ammonium bisulfite, ammonium bisulfite, ammonium sulfite waxay la falgashaa chlorinated diazobenzene si ay u sameyso phenylhydrazine disulfonate, ka dibna waxay la falgashaa hydrochloric acid hydrolysis iyo falanqaynta acid falcelinta, iyo ka dib qallajinta, 4 methoxyphenylhydrazine hydrochloride waa la diyaariyey. |
