Hoʻolauna

ʻO ka ʻakika, i kapa ʻia hoʻi ka waikawa, he mea hoʻohuihui. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.

 

ʻAno:

-Ke ʻano: ʻo ka waika ka pauka crystalline keʻokeʻo.

-Poloke mole: C6H4BrNO2.

-Molecular kaumaha: 206.008g/mol.

-Ka helu hoʻoheheʻe: ma kahi o 132-136 degere Celsius.

- Paʻa i ka lumi wela a hiki ke hoʻoheheʻe ʻia i kekahi mau mea hoʻoheheʻe organik.

 

E hoʻohana:

Hoʻohana pinepine ʻia ka acid ma ke ʻano he mea maka a i ʻole waena i ka synthesis organik.

-Hiki ke hoʻohana ʻia e synthesize i ke ʻano o nā pūhui heterocyclic nitrogen, e like me pyridine a me pyridine derivatives.

-Hiki ke hoʻohana ʻia no ka hoʻomākaukau ʻana i nā pūhui hana biologically, e like me nā pesticides, nā lāʻau lapaʻau a me nā mea hoʻonaninani.

 

Kaʻina hoʻomākaukau:

Hoʻomākaukau ʻia ka ʻakika -¾ e ka hopena o ka waikawa bromo-nicotinic. ʻO ke ʻano hana synthesis maʻamau ka hana ʻana i ka waikawa nicotinic me ka bromoethanol ma lalo o nā kūlana alkaline, a ukali ʻia e ka acidification e loaʻa ai ka huahana.

 

ʻIke palekana:

-pono ka ʻakika e hahai i nā kaʻina hana palekana o ka lab i ka wā e hoʻohana ai.

- Hiki ke hoʻonāukiuki i nā maka, ka ʻili a me ka ʻōpū hanu, no laila e pale ʻia ka hoʻopili pololei ʻana i ka wā o ka hana.

-ma ka mālama ʻana a me ka hoʻohana ʻana pono e makaʻala e pale i ka hoʻopili ʻana me nā oxidants, nā ʻakika ikaika a me nā mea ʻē aʻe, i mea e pale aku ai i nā mea pōʻino a i ʻole ka hopena.

-Inā pono, e hana i loko o kahi wahi hoʻoluʻu maikaʻi, e hoʻokomo i nā mīkina lima pale, nā aniani pale a me nā maka pale. Inā inhaled a ʻike ʻia paha, e ʻimi i ka ʻōlelo aʻoaʻo olakino.
