Hoʻolauna
ʻO ka 5-fluoro-2-nitrobenzoic acid (5-fluoro-2-nitrobenzoic acid) he mea hoʻohuihui mea ola me ke ʻano kemika C7H4FNO4. Eia ka wehewehe ʻana o kona ʻano, hoʻohana, hoʻomākaukau a me ka ʻike palekana.
ʻAno:
-Nani: 5-fluoro-2-nitrobenzoic acid he keʻokeʻo a i ʻole keʻokeʻo keʻokeʻo crystalline pauka.
-Ka helu hehee: Ma kahi o 172°C.
-Solubility: Hiki ke hoʻoheheʻe ʻia i loko o ka wai, hiki ke hoʻoheheʻe ʻia i kekahi mau mea hoʻoheheʻe organik e like me nā ʻona a me nā esters.
E hoʻohana:
ʻO ka synthesis kemika: ʻO ka 5-fluoro-2-nitrobenzoic acid he mea hoʻohana maʻamau i ka synthesis intermediate, hiki ke hoʻohana ʻia e synthesize i nā pūhui organik ʻē aʻe, e like me nā lāʻau lapaʻau, pesticides a me nā mea hoʻonaninani.
-Nā hana noiʻi ʻepekema: Ma muli o kāna ʻano i loaʻa nā hui fluorine a me nitro, 5-fluoro-2-nitrobenzoic acid he mau waiwai kemika kūikawā a hiki ke hoʻohana ʻia no ka noiʻi a me nā hoʻokolohua hoʻokolohua.
Hanana:
ʻO ke ʻano o ka hoʻomākaukau ʻana o 5-fluoro-2-nitrobenzoic acid e loaʻa pinepine ʻia e ka hopena fluorination o 2-nitrobenzoic acid.
1. ʻO ka mua, ua hoʻopili ʻia ka 2-nitrobenzoic acid me kahi mea hana fluorinating (e like me ka hydrogen fluoride a i ʻole ka sodium fluoride).
2. Ma hope o ka hopena, ua loaʻa ka huahana 5-fluoro-2-nitrobenzoic acid.
Pono e hoʻomaopopo ʻia i ka wā o ka hoʻomākaukau ʻana, pono e hoʻohana ʻia nā kūlana hana hoʻokolohua kūpono a me nā ana palekana e hōʻoia i ka palekana o ka hoʻokolohua.
ʻIke palekana:
- Manaʻo ʻia ʻo 5-fluoro-2-nitrobenzoic acid he mea palekana ma lalo o nā kūlana maʻamau, akā pono e mālama pono ʻia a hahai i nā hana hoʻokolohua kūpono.
-Ma ka hoʻopili ʻana me kēia pūhui, pono e pale ʻia ka pili ʻana i ka ʻili a me ka inhalation o kona lepo.
-Ma ka hoʻohana ʻana a me ka mālama ʻana, e ʻoluʻolu e pale pono i nā lako hale hana, a hoʻokō i nā alakaʻi palekana kūpono.
-Ina he ulia a i manaoia he make, e imi koke i ka lapaau a lawe mai i ka pepa ikepili palekana o ka hui.
