Hoʻolauna
ʻO ka ʻakika (acid) he mea hoʻohuihui. Loaʻa iā ia kahi ʻano kemika o C6H4FNO2 a me ke kaumaha molekala o 141.1g/mol.
Ma ke ʻano o ke ʻano, he paʻa keʻokeʻo a melemele ka waikawa. He ikaika ka oxidation a me ka corrosion, hiki ke hoʻoheheʻe ʻia i kekahi mau mea hoʻoheheʻe organik e like me ka waiʻona a me ka ether, akā ʻilihune ka solubility i ka wai.
ʻO kekahi o ka hoʻohana nui ʻana o ka waikawa ma ke ʻano he waena i ka synthesis organik. Hoʻohana maʻamau ia i ka hoʻomākaukau ʻana i nā lāʻau lapaʻau, nā pesticides a me nā mea hoʻohui ʻē aʻe. Eia kekahi, hiki ke hoʻohana ʻia ma ke ʻano he ligand o kahi organometallic complex.
ʻO ke ʻano o ka hoʻomākaukau ʻana o ka calcium e loaʻa pinepine ʻia e kēia ʻano hana: ʻO ka mea mua, ua hana ʻia ka 2-fluoropyridine me ka acetone a me ka alumini trichloride i loko o ka dichloromethane e hana i ka 2-fluoropyridine-4-methanone. Ma hope mai, ua hoʻololi ʻia ka 2-fluoropyridine-4-methanone i fluoracid ma o ka hopena acid-catalyzed.
E pili ana i ka ʻike palekana, ʻo ka waikawa he mea hoʻokalakupua e hoʻopilikia i ke olakino kanaka a me ke kaiapuni. E hahai i nā hana palekana kūpono i ka wā o ka lawelawe ʻana a me ka mālama ʻana e pale aku i ka pili ʻana me ka ʻili, nā maka a me ka ʻōpū hanu. Pono e hoʻohana ʻia nā lako pale pilikino e like me nā mīkina lima lab, nā maka aniani a me nā pale pale i ka wā e hoʻohana ai. Eia kekahi, pono e mālama ʻia i kahi maloʻo maloʻo, kahi mamao mai ke ahi a me nā mea oxidizing. Inā pono, e hana i loko o kahi kaiapuni maikaʻi. Ma ke ʻano o ka hoʻolei ʻana i ka ʻōpala, pono e mālama ʻia nā kānāwai kūloko a me nā lula.
