Intshayelelo

I-4-nitrobenzoylhydrazide yi-organic compound.

 

Umgangatho:

I-4-Nitrobenzoylhydrazide yikristale etyheli ukuya kuorenji eqinileyo enyibilika kwi-chloroform, ethanol, kunye nezinyibilikisi ezineasidi, kwaye phantse ayinyibiliki emanzini. Iyatsha kwaye iyadubula kwaye kufuneka iphathwe ngononophelo.

 

Sebenzisa:

I-4-nitrobenzoylhydrazide yi-reagent yekhemikhali esetyenziswa ngokuqhelekileyo njenge-coupling reagent, i-amination reagent kunye ne-cyanide reagent kwi-organic synthesis.

 

Indlela:

Indlela yokulungiselela i-4-nitrobenzoylhydrazide isoloko isebenzisa i-reaction ye-benzaldehyde kunye ne-hydrogen ammonia, e-nitrified ukuba ivelise i-4-nitrobenzaldehyde, kwaye ke i-4-nitrobenzoylhydrazide ifunyenwe ngokunciphisa ukusabela.

 

Ulwazi ngoKhuseleko:

I-4-Nitrobenzoylhydrazide inomngcipheko omkhulu wokudubula kwaye kufuneka ithathelwe ingqalelo ukuthintela ukudibana ngqo nolusu kunye nokuphefumla. Amanyathelo afanelekileyo kufuneka athathwe ngexesha lokuphatha kunye nokugcinwa ukuqinisekisa ukhuseleko. Qonda ngononophelo ulwazi olufanelekileyo lokhuseleko phambi kokusetyenziswa: kwaye ulandele indlela echanekileyo yokuphatha nokusetyenziswa.
