Hoʻolauna

ʻO ia ka mea hoʻohui kemika ʻo ia ka C5H2ClFN2O2. ʻO kēia ka wehewehe ʻana o kona ʻano, hoʻohana, hana a me ka ʻike palekana:

 

ʻAno:

-Nani: Keʻokeʻo a i ʻole melemele māmā pauka paʻa.

-Ka helu hoʻoheheʻe: ʻO ka helu heheʻe o ka hui ma kahi o 160-165 degere Celsius.

-Solubility: Hiki ke hoʻoheheʻe ʻia i loko o nā solvents organik e like me dimethylmethylphosphinate a me dimethylformamide, akā haʻahaʻa kona solubility i ka wai.

 

E hoʻohana:

-ʻO kekahi o ka hoʻohana nui ʻana o ka pesticide ma ke ʻano he insecticide a me ka fungicide i ka māla mahiʻai.

- Hiki ke hoʻohana ʻia e synthesize i nā mea hoʻohui ʻē aʻe, e like me nā intermediates synthetic no nā lāʻau lapaʻau a me nā pesticides.

 

Kaʻina hoʻomākaukau:

-a i ʻole hiki ke synthesized e ka hopena nitro. ʻO ke ʻano hana synthetic maʻamau ka hopena o 5-chloro-2-aminopyridine me ka nitrite, a ukali ʻia e ka fluorination me kahi fluorinating reagent.

 

ʻIke palekana:

-ʻo ia ka mea hoʻohui kūlohelohe a pono e hoʻohana ʻia e like me nā kaʻina hana palekana kūpono.

-He mea ʻawaʻawa paha ia i ke kaiapuni, a pono e lawe ʻia nā hana palekana e hōʻemi i kona hopena i ke kaiapuni.

-E hoʻohana i nā mīkina lima pale, nā makaaniani palekana a me nā lole pale i ka wā e hoʻohana ai i kēia pūhui.

- Pono e mālama ʻia ma kahi maloʻo a maʻalili, a ma kahi mamao aku i nā mea puhi ahi a me nā oxidants.

-Ma mua o ka hoʻohana ʻana, pono ʻoe e hoʻomaopopo i ka ʻikepili palekana e pili ana i ka pūhui me ka kikoʻī a hahai i kāna hana kūpono a me ka hoʻokuʻu ʻana.
