Hoʻolauna

He pūhui olaola ia me ke kumu hoʻoheheʻe kemika o C6H5ClFN. Eia ka wehewehe ʻana o nā waiwai, hoʻohana, hoʻomākaukau a me ka ʻike palekana o ka pūhui:

 

ʻAno:

-Ke ʻano: He wai kalamele ʻole ia.

-Pila paila: ma kahi o 126-127°C.

-Density: ma kahi o 1.36g/cm³.

-Solubility: Hiki ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe organik, e like me ka ethanol, ether a me dimethylformamide.

 

E hoʻohana:

- hoʻohana nui ʻia ma ke ʻano he waena i ka synthesis organik a hiki ke hoʻohana ʻia e synthesize i nā pūhui organik ʻē aʻe.

-Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻomaka no ka hoʻohui ʻana i ka lāʻau, ka pesticide synthesis a me ka synthesis dye.

 

Kaʻina hoʻomākaukau:

-a i ʻole hiki ke hoʻomākaukau ʻia e ka hopena halogenation o pyridine. ʻO ka mua, ʻo ka pyridine a me ka waikawa acetic e hana i kahi hopena chlorination e hana i ka 2-chloropyridine. Hoʻololi ʻia ka 2-chloropyridine i 2-chloro-3-fluoropyridine e ka hopena fluorination. ʻO ka hope, ua methylated ka 2-chloro-3-fluoropyridine me ka hoʻohana ʻana i ka hopena methylation.

 

ʻIke palekana:

-ʻo ia ka mea hoʻonāukiuki e hoʻonāukiuki i nā maka a me kaʻili.

-I ka wā o ka hoʻohana ʻana a me ka mālama ʻana, pono e lawe ʻia nā hana palekana kūpono, me ke komo ʻana i nā aniani pale a me nā mīkina lima.

-E hōʻalo i ka hoʻohuʻu ʻana i ka mahu o ka mea hoʻohui a hōʻoia i ka hana ʻia i loko o kahi kaiapuni maikaʻi.

-I ka mālama ʻana a me ka mālama ʻana, e haʻalele i ke ahi a me nā mea oxidizing e pale i ka hopena o ke ahi a me ka pahū.

-I ka wā e hoʻohana ai, pono e uku ʻia i ka hoʻokō ʻana i nā kaʻina hana palekana kūpono a me nā lula.
