Hoʻolauna

ʻO ka 4-Nitrobenzamide(4-Nitrobenzamide) he mea hoʻohuihui mea ola me ke ʻano kemika o C7H6N2O3, ʻo ia ka pauka crystalline melemele.

 

ʻO nā waiwai nui o 4-Nitrobenzamide ka:

-ka mānoanoa: 1.45 g/cm ^ 3

-Solubility: Hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i ka waiʻona a me nā mea hoʻoheheʻe ketone

-kahi hoʻoheheʻe: 136-139 ℃

-Paʻa wela: kūpaʻa wela

 

ʻO nā hoʻohana nui o 4-Nitrobenzamide ka:

-Ma ke ʻano he mea waena i ka synthesis organik: Hiki ke hoʻohana ʻia e synthesize i nā pūhui organik ʻē aʻe, e like me nā lāʻau lapaʻau a me nā mea hoʻonaninani.

-E like me ka ʻepekema noiʻi reagent: hoʻohana ʻia no kekahi mau hopena i loko o nā kemika analytical a me nā hale kemika kūlohelohe.

 

Hiki ke hoʻokō ʻia ka hoʻomākaukau ʻana o 4-Nitrobenzamide ma o nā pae aʻe:

1. Hoʻohui i ka p-nitroaniline (4-Nitroaniline) a me ka waika formic keu i ka reactor.

2. E ho'āla i nā mea hoʻonāuki ma kahi mahana kūpono a hoʻohui i kahi catalyst kumu.

3. Ma hope o kekahi manawa pane, lawe ʻia a hoʻomaʻemaʻe ʻia ka huahana.

 

No ka ʻike palekana o 4-Nitrobenzamide, pono e hoʻomaopopo ʻia nā ʻōlelo aʻe:

- Hiki i ka 4-Nitrobenzamide ke hoʻonāukiuki i ka ʻili, nā maka, a me ka ʻōpū hanu a pono e pale ʻia.

-E hoʻohana i nā mea pale pilikino kūpono e like me nā aniani palekana, nā mīkina lima a me nā lole pale i ka wā e hana ai.

- Pono e hana ʻia ma kahi wahi hoʻoluʻu maikaʻi a mamao aku i ke ahi a me nā kumu wela.

-I ka wā mālama a me ka lawe ʻana, pono e mālama ʻia e pale aku i nā hopena me nā kemika ʻē aʻe.

-Ke honi ʻoe a pili ʻole paha me 4-Nitrobenzamide, pono ʻoe e hoʻōki i ka hoʻohana koke ʻana a e ʻimi i ke kōkua olakino.

 

No ka kuhikuhi ʻana kēia ʻike, e ʻoluʻolu e hoʻohana a mālama pono iā 4-Nitrobenzamide e like me ke kūlana maoli.
