Hoʻolauna

ʻO ka ʻakika he pūhui olaola me ke ʻano kemika C7H7NO2. He paʻa kalakala kala ʻole, hiki ke hoʻoheheʻe ʻia i ka wai a me nā mea hoʻoheheʻe organik.

 

He ʻokoʻa ka hoʻohana ʻana o ka acid. Hiki ke hoʻohana ʻia ma ke ʻano he intermediate in organic synthesis no ka hoʻomākaukau ʻana i nā pūhui ʻē aʻe. Hiki iā ia ke hana ma ke ʻano he ligand no nā hui organometallic a komo i nā hopena catalytic. Eia kekahi, hiki ke hoʻohana ʻia i ka synthesis o kekahi mau lāʻau lapaʻau.

 

Nui nā ala e hoʻomākaukau ai i ka ICT. ʻO kekahi ʻano hana maʻamau ʻo ka synthesis ma ka mālama ʻana a me ka oxidation o toluene. ʻO ka mea kikoʻī, hoʻopili mua ʻia ka toluene me ka acetaldehyde i mua o kahi mea hoʻoheheʻe e hana i ka 3-methyl-4-picolinic acid ester, a laila hoʻokau ʻia i ka hydrolysis acid e loaʻa ai ka huahana i manaʻo ʻia.

 

He kiʻekiʻe ka palekana o ka waikawa, akā pono e hoʻolohe ʻia kekahi mau mea palekana. E hoʻohana i nā mea pale kūpono e like me nā maka aniani a me nā mīkina lima i ka wā e hana ai. Hōʻalo i ka hanu ʻana i ka lepo a me ke kinoea i loaʻa mai a pale i ka pili ʻana me ka ʻili. I ka wā o ka mālama ʻana a me ka lawe ʻana, pono e nānā ʻia i nā hana hōʻoiaʻiʻo i ke ahi, pale ahi a me ka pahū. I ka hihia o ka ʻai ʻana a i ʻole ka hoʻopili ʻana, e ʻimi koke i ka ʻōlelo aʻoaʻo olakino a lawe i ka pepa ʻikepili palekana o kēia huahana i ka haukapila.
