4-Methoxyphenylhydrazine hydrochloride（CAS# 19501-58-7) Nga korero
| Whakamahi | Ko te 4-methoxyphenylhydrazine hydrochloride he takawaenga, i te nuinga o te waa ki te whakaputa i nga pūhui phenylhydrazine, ka taea hoki te whakamahi ki te whakaputa i etahi atu hua matū, penei i te 4-nitroindole me te apixaban. Ka whakamahia ki nga waikano me nga takawaenga rongoa |
| Whakaritenga | Ka taea te whakarite 4-methoxyphenylhydrazine hydrochloride mai i te aniline na roto i te tauhohenga diazotization. Tangohia aniline, waikawa pūmāota me te konutai nitrite, te ōwehenga molar i waenganui ia ratou ko 1: 3.2: 1.0, tuatahi tāpiri waikawa pūmāota, ka tāpiri haukinia nitrite i 5 ℃, ka tauhohe i 0 ~ 20 ℃ mō te 40 meneti ki te whakaputa i te diazobenzene māota; E ai ki te tauwehenga molar o te aniline ki te 1: 3.5: 2.5, ka taapirihia te haukinia sulfite me te waikawa waikawa, me te whakaheke, te whakamaarama me te waikawa i roto i te kettle whakaheke, ko te wa whakaheke ko te 60 ~ 70 meneti, me te whakamaarama me te waikawa. 50 meneti te wa. Tuatahi, ka tauhohe te ammonium sulfite ki te waikawa hauhauwai te taikaha hei whakaputa i te ammonium bisulfite, te ammonium bisulfite, te ammonium sulfite te tauhohe me te diazobenzene chlorinated ki te hanga i te phenylhydrazine disulfonate, katahi ka tauhohe ki te waikawa pūhaumāota mo te hauhauwai me te tātari waikawa Te tauhohenga, a i muri i te whakamaroke miro, 4 kua whakaritea te methoxyphenylhydrazine hydrochloride. |
