Isingeniso

I-4-nitrobenzoylhydrazide iyinhlanganisela yemvelo.

 

Ikhwalithi:

I-4-Nitrobenzoylhydrazide iyikristale eqinile ephuzi ukuya kuwolintshi encibilika ku-chloroform, i-ethanol, nezincibilikisi ezine-asidi, futhi cishe ayincibiliki emanzini. Iyavutha futhi iyaqhuma futhi kufanele iphathwe ngokucophelela.

 

Sebenzisa:

I-4-nitrobenzoylhydrazide iyi-reagent yamakhemikhali evame ukusetshenziswa njenge-coupling reagent, i-amination reagent kanye ne-cyanide reagent ku-organic synthesis.

 

Indlela:

Indlela yokulungiselela ye-4-nitrobenzoylhydrazide ivamise ukusebenzisa ukusabela kwe-benzaldehyde ne-hydrogen ammonia, efakwa i-nitrified ukuze ikhiqize i-4-nitrobenzaldehyde, bese i-4-nitrobenzoylhydrazide itholwa ngokusabela kokunciphisa.

 

Ulwazi Lokuphepha:

I-4-Nitrobenzoylhydrazide isengozini enkulu yokuqhuma futhi kufanele kuqikelelwe ukugwema ukuthintana ngqo nesikhumba kanye nokuhogela. Izinyathelo ezifanele kufanele zithathwe ngesikhathi sokuphatha nokugcinwa ukuze kuqinisekiswe ukuphepha. Qonda ngokucophelela ulwazi olufanele lokuphepha ngaphambi kokusetshenziswa: futhi ulandele indlela efanele yokuphatha nokusebenzisa.
