5-bromo-2-methylphenylhydrazine hydrochloride（CAS# 214915-80-7)

Hoʻolauna

ʻO ka hydrochloride he mea hoʻohuihui olaola me ke ʻano kemika C7H8BrN2 · HCl. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana:

ʻAno:

-Ke ʻano: kala ʻole a melemele paha

-Ka helu heheʻe: Ma kahi o 155-160 degere Celsius

-Solubility: Hiki ke hoʻoheheʻe ʻia i ka wai, ʻoi aku ka maikaʻi o ka solubility i ka ethanol a me ka etera

-Toxicity: Loaʻa i ka hui ke ʻano o ka ʻona a pono e mālama ʻia me ka mālama a pale aku i ka inhalation a me ka pili ʻili.

E hoʻohana:

-Hiki ke hoʻohana ʻia ka hydrochloride e synthesize i nā mea hoʻohuihui ʻē aʻe, e like me nā intermediates pharmaceutical a me nā dyes.

-Hiki ke hoʻohana ʻia ma ke ʻano he reagent synthesis organik koʻikoʻi, e hana ana ma ke ʻano he catalyst i nā hopena synthesis organik

Hanana:

Hiki ke hana ʻia ke ʻano hoʻomākaukau o ka hydrochloride e nā ʻanuʻu aʻe:

1. E hoʻoheheʻe i ka 2-bromo-5-methylaniline i loko o ka ethanol

2. E hoʻohui i ka sodium nitrite a me ka waika hydrochloric, ka hopena diazotization ma ke ana wela

3. E hoʻohui i ka etera anhydrous no ka unuhi ʻana, a laila e hoʻohana i ke kinoea hydrogen chloride e hoʻopiha i ka papa etera e loaʻa ai ka huahana.

4. ʻO ka hope, loaʻa ka hydrochloride ma ka crystallization

ʻIke palekana:

- He mea ʻawaʻawa ka hui a pono e mālama ʻia me ka mālama

-E noʻonoʻo i nā hana pale i ka wā e hoʻohana ai a mālama ai, e pale i ka inhalation a i ʻole ka pili ʻana me ka ʻili a me nā maka

-E noʻonoʻo i nā kūlana ventilation maikaʻi i ka wā o ka hana

-Inā pili ʻoe i ka ʻili a i ʻole nā ​​maka, holoi koke me ka wai nui a ʻimi i ke kōkua olakino

- E ʻoluʻolu e mālama a mālama pono i ka pūhui, e pale i ka hoʻopili ʻana me nā oxidants a me nā waikawa ikaika e pale ai i nā kūlana palekana
