Hoʻolauna
ʻO ka 2-Chloro-4-fluorobenzoic acid he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka 2-chloro-4-fluorobenzoic acid:
ʻAno maikaʻi:
- Ke ʻano: 2-Chloro-4-fluorobenzoic acid he paʻa keʻokeʻo keʻokeʻo.
- Solubility: He haʻahaʻa ka solubility i ka wai, akā maikaʻi ka solubility i nā mea hoʻoheheʻe organik (e laʻa, ethanol, acetone).
- Paʻa: He hui paʻa ia, akā pono e pale ʻia ka hoʻopili ʻana me nā oxidants ikaika a me nā waikawa.
E hoʻohana:
- Nā mea waena kemika: hiki ke hoʻohana ʻia ka 2-chloro-4-fluorobenzoic acid e like me nā intermediates kemika i ka synthesis organik.
- Surfactant: Hiki ke hoʻohana ʻia ma ke ʻano he mea maka no nā surfactants a loaʻa iā ia ka hana ʻili maikaʻi a me nā waiwai hoʻopuehu.
- Nā mea paʻi kiʻi kiʻi: hiki ke hoʻohana ʻia ka 2-chloro-4-fluorobenzoic acid e hoʻomākaukau ai i nā mea photosensitive, e like me nā mea hoʻopili māmā.
Hanana:
Hiki ke loaʻa ka 2-Chloro-4-fluorobenzoic acid e ka fluorochloro-substitution reaction o ka p-dichlorobenzoic acid a i ʻole difluorobenzoic acid. Hiki i nā ʻano hana hoʻomākaukau kikoʻī ke komo i ka fluorochloro-substitution, fluorination a i ʻole nā hopena hoʻololi kūpono.
ʻIke palekana:
- Ka 'awaʻawa: 2-chloro-4-fluorobenzoic acid he hui organofluorine, ʻoi aku ka ʻona ma mua o nā pūhui organofluorine maʻamau. Eia nō naʻe, pono e mālama ʻia e pale aku i ka inhalation a i ʻole pili.
- Hoʻohaunaele: Hiki iā ia ke hōʻeha i ka maka, ka ʻili a me ka ʻōpū hanu a pono e holoi koke ʻia ma hope o ka hoʻopili ʻana.
- Nā mea hoʻopau ahi: I loko o ke ahi, pono e hoʻokō ʻia ke kinai ʻana me kahi mea hoʻopau kūpono e like me carbon dioxide, foam a i ʻole ka pauka maloʻo, e pale aku i ka hoʻohana ʻana i ka wai e kinai i ke ahi no ka mea he haʻahaʻa haʻahaʻa i ka wai.
- E mālama ʻia: 2-Chloro-4-fluorobenzoic acid e mālama ʻia i kahi maloʻo a maikaʻi-ventilated, ma kahi mamao mai ke ahi a me nā mea hoʻomake ikaika.
