Hoʻolauna

ʻO ka ʻakika (acid) he mea hoʻohuihui. ʻO C6H4FNO2 kona kumu hoʻohālikelike a ʻo kona kaumaha molekala he 141.10g/mol.

 

ma ke ʻano o ke ʻano, he paʻa keʻokeʻo ka waikawa. Paʻa ia ma ka lumi wela, akā hiki ke decompose i nā wela kiʻekiʻe a i ʻole i ka pilina me kahi kumu hoʻā. Hiki ke hoʻoheheʻe ʻia i loko o ka wai a me nā mea hoʻoheheʻe kūlohelohe e like me ka ethanol a me ka dimethylformamide.

 

Loaʻa i ka Acid kekahi mau noi i ka noiʻi kemika a me nā kahua lāʻau lapaʻau. Ma ke ʻano he waena waena i ka synthesis organik, hiki ke hoʻohana ʻia i ka synthesis o nā pūhui ʻē aʻe, e like me nā mea biologically active, nā lāʻau lapaʻau a me nā mea hoʻonaninani. Hiki ke hoʻohana ʻia ma ke ʻano he ligand no ka hoʻololi metala catalyzed reactions.

 

ma ke ʻano hoʻomākaukau, nui nā ʻano synthetic o ka waikawa. ʻO ke ala maʻamau ka loaʻa ʻana o ka huahana i hoʻopaʻa ʻia ma ka hana ʻana i ka pyridine me ka hydrogen fluoride, a ukali ʻia e ka carboxylation.

 

E pili ana i ka ʻike palekana, ʻo ka waikawa he mea hoʻohuihui organik, a pono ʻoe e hoʻolohe i ka hana palekana i ka wā e hoʻohana ai. Hiki iā ia ke hōʻeha a pōʻino i ka maka, ka ʻili a me ka ʻōnaehana hanu. E hoʻohana i nā mea pale kūpono e like me nā mīkina lima, nā maka aniani a me nā maka i ka wā o ka hana. Ma hope o ka mālama ʻana, pono e nānā i ka hoʻomaʻemaʻe manawa a me ka hoʻolei ʻana i ka ʻōpala i mea e pale ai i ka haumia i ke kaiapuni.
