ʻO ia ka mea hoʻohui kemika nona ka ʻano kemika C8H6BrN. ʻO kēia ka wehewehe ʻana o kona ʻano, hoʻohana, hana a me ka ʻike palekana:
ʻAno:
-Nani: ʻAʻohe kala i ka aniani melemele māmā
-Ka helu heheʻe: 64-68 degere Celsius
-Pila paila: 294-296 degere Celsius
-Ka nui: 1.51 g/ml
-Solubility: Hiki ke hoʻoheheʻe ʻia i ka wai, hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe maʻamau e like me ka ethanol, ether a me benzene
E hoʻohana:
Hoʻohana pinepine ʻia ʻo ia ma ke ʻano he waena i ka synthesis organik a hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā pūhui organik ʻē aʻe. Hiki ke hoʻohana ʻia i loko o ka pharmaceutical synthesis, pesticide synthesis, a ma ka ʻoihana kala a me ka pena.
Ka Papa Hana: Ka hoomakaukau ana o
hana maʻamau e nā ʻanuʻu aʻe:
1. Hoʻopili i ka p-methylbenzonitrile me ka bromine ma lalo o nā kūlana hoʻololi kūpono e hana i ka phenol.
ʻIke palekana:
-ʻo ia ka mea hoʻohui organik a pono e mālama ʻia me ka akahele.
-I ka wā o ka hana, pono e mālama ʻia e pale aku i ka hoʻopili pololei ʻana me ka ʻili, nā maka a me ka ʻōpū hanu.
-E hoʻohana i nā lako pale pilikino kūpono, e like me nā mīkina lima lima a me nā maka aniani.
- Pono e hana ʻia ma kahi wahi e hoʻoheheʻe maikaʻi ʻia a pale i ka hoʻohu ʻana i kona mahu a lepo paha.
-Inā komo hewa ʻole, e ʻimi koke i ke kōkua lapaʻau a hōʻike i ka pahu a i ʻole ka lepili no ka ʻike.
E ʻoluʻolu, pono e hoʻohana ʻia nā mea kemika ma lalo o nā kūlana hoʻokolohua kūpono a hahai i nā kaʻina hana palekana kūpono.
