4-Methoxyphenylhydrazine hydrochloride（CAS# 19501-58-7) ʻIkepili
| Hoʻohana | ʻO 4-methoxyphenylhydrazine hydrochloride ka mea waena, hoʻohana nui ʻia e hana i nā pūhui phenylhydrazine, a hiki ke hoʻohana ʻia e hana i nā huahana kemika ʻē aʻe, e like me 4-nitroindole a me apixaban. Hoʻohana ʻia i nā mea pena a me nā mea waena lāʻau lapaʻau |
| Hoʻomākaukau | Hiki ke hoʻomākaukau ʻia ka 4-methoxyphenylhydrazine hydrochloride mai ka aniline ma o ka hopena diazotization. E lawe i ka aniline, hydrochloric acid a me ka sodium nitrite, ʻo ka lākiō molar ma waena o lākou he 1: 3.2: 1.0, e hoʻohui mua i ka waika hydrochloric, a laila e hoʻohui i ka ammonium nitrite ma 5 ℃, a hana i ka 0 ~ 20 ℃ no 40 mau minuke e hana i ka diazobenzene chlorinated; E like me ka lākiō molar o aniline i 1: 3.5: 2.5, hoʻohui ʻia ka ammonium sulfite a me ka waika hydrochloric, a me ka hoʻohaʻahaʻa, hydrolysis a me ka acidification i lawe ʻia i loko o ka hoʻohaʻahaʻa kettle, ʻo ka manawa hoʻemi he 60 ~ 70 mau minuke, a me ka hydrolysis a me ka acidification. he 50 minuke ka manawa. ʻO ka mua, hoʻopili ka ammonium sulfite me ka waika hydrochloric keu aku e hana i ka ammonium bisulfite, ammonium bisulfite, ammonium sulfite reacts me ka chlorinated diazobenzene e hana i ka phenylhydrazine disulfonate, a laila hoʻopili me ka waika hydrochloric no ka hydrolysis a me ka nānā ʻana i ka waikawa ʻO ka hopena, a ma hope o ka maloʻo ʻana, 4 Hoʻomākaukau ʻia ka methoxyphenylhydrazine hydrochloride. |
