ʻO 4-nitrobenzoylhydrazide kahi mea hoʻohuihui.
ʻAno maikaʻi:
ʻO ka 4-Nitrobenzoylhydrazide he melemele a ʻalani ka paʻa kristal i hiki ke hoʻoheheʻe ʻia i loko o ka chloroform, ethanol, a me nā mea hoʻoheheʻe waika, a aneane hiki ʻole ke hoʻoheheʻe ʻia i ka wai. He mea puhi a pahū a pono e mālama pono ʻia.
E hoʻohana:
ʻO ka 4-nitrobenzoylhydrazide he mea hoʻoheheʻe kemika i hoʻohana mau ʻia e like me ka reagent hui, amination reagent a me ka cyanide reagent i ka synthesis organik.
Hanana:
Hoʻohana pinepine ʻia ke ʻano hoʻomākaukau o 4-nitrobenzoylhydrazide i ka hopena o benzaldehyde a me hydrogen ammonia, kahi i nitrified e hoʻohua i ka 4-nitrobenzaldehyde, a laila loaʻa ka 4-nitrobenzoylhydrazide ma ka hopena hoʻemi.
ʻIke palekana:
ʻO 4-Nitrobenzoylhydrazide ka pilikia nui o ka pahū ʻana a pono e mālama ʻia e pale i ka hoʻopili pololei ʻana me ka ʻili a me ka inhalation. Pono e mālama pono i ka mālama ʻana a me ka mālama ʻana i mea e palekana ai. E hoʻomaopopo pono i ka ʻike palekana pili ma mua o ka hoʻohana ʻana: a hahai i ke ʻano kūpono o ka lawelawe ʻana a me ka hoʻohana ʻana.
