4-Methoxyphenylhydrazine hydrochloride (CAS# 19501-58-7) Boitsebiso
Sebelisa | 4-methoxyphenylhydrazine hydrochloride ke e bohareng, e sebelisoang haholo ho hlahisa metsoako ea phenylhydrazine, hape e ka sebelisoa ho hlahisa lihlahisoa tse ling tsa lik'hemik'hale, tse kang 4-nitroindole le apixaban. E sebelisoa ho lidae le li-intermediates tsa meriana |
Tokisetso | 4-methoxyphenylhydrazine hydrochloride e ka lokisoa ho tloha ho aniline ka karabelo ea diazotization. Nka aniline, hydrochloric acid le sodium nitrite, karolelano ea molar pakeng tsa tsona ke 1: 3.2: 1.0, qala ka ho eketsa hydrochloric acid, ebe u eketsa ammonium nitrite ho 5 ℃, 'me u arabe ka 0 ~ 20 ℃ metsotso e 40 ho hlahisa diazobenzene e chlorinated; Ho ea ka karo-karolelano ea molar ea aniline ho 1: 3.5: 2.5, ammonium sulfite le hydrochloric acid li eketsoa, 'me phokotso, hydrolysis le acidification li etsoa ka kettle ea phokotso, nako ea ho fokotsa ke metsotso e 60-70, le hydrolysis le acidification. nako ke metsotso e 50. Taba ea pele, ammonium sulfite e sebetsana le acid e feteletseng ea hydrochloric ho hlahisa ammonium bisulfite, ammonium bisulfite, ammonium sulfite e kopana le chlorinated diazobenzene ho etsa phenylhydrazine disulfonate, ebe e arabela ka hydrochloric acid bakeng sa hydrolysis le acid analysis The reaction, and after spin-drying, Methoxyphenylhydrazine hydrochloride e lokiselitsoe. |
