Hoʻolauna pōkole
ʻO ka 4-Chloro-2-fluorobenzoic acid he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:
ʻAno maikaʻi:
ʻO ka 4-Chloro-2-fluorobenzoic acid he aniani paʻa, ʻaʻohe kala a melemele paha. He non-volatile ma ka lumi wela. He ʻono ʻono kona a hiki ke hoʻoheheʻe ʻia i loko o nā solvents organik e like me ka methanol, ethanol, methylene chloride, etc.
E hoʻohana:
ʻO 4-Chloro-2-fluorobenzoic acid ka nui o nā noi i ka ʻoihana kemika. Hoʻohana pinepine ʻia ma ke ʻano he mea hoʻomaka a i ʻole waena i ka synthesis organik. Hiki ke hoʻohana ʻia ma ke ʻano he meaʻai no nā catalysts a me nā mea uila.
Hanana:
Hiki ke loaʻa ka 4-Chloro-2-fluorobenzoic acid ma ka chlorination o ka p-fluorobenzoic acid. Ma keʻano laulā, hiki ke hoʻopili ʻia ka hydrogen chloride a i ʻole ka waikawa chlorous me ka thionyl chloride a i ʻole sulfinyl chloride ma lalo o nā kūlana acidic, a ukali ʻia e ka hopena me ka hydrogen fluoride e loaʻa ai ka 4-chloro-2-fluorobenzoic acid.
ʻIke palekana:
Pono e mālama ʻia kēia mau mea palekana i ka wā e lawelawe ai i ka waikawa 4-chloro-2-fluorobenzoic: pale i ka pili ʻana me ka ʻili a me nā maka, a e hoʻolohe i nā hana pale e like me ke komo ʻana i nā aniani pale a me nā mīkina lima. Pono e hana ʻia ma kahi wahi i hoʻoluʻu maikaʻi ʻia e pale ai i ka inhalation a i ʻole ka ʻai ʻana. E hōʻalo i ka hoʻopili ʻana me nā mea puhi ahi a pale aku i nā lapalapa ākea a i ʻole nā wela kiʻekiʻe. Pono e hoʻopaʻa paʻa ʻia ke hoʻohana ʻia a mālama ʻia a haʻalele ʻia mai nā waikawa, nā kumu, a me nā mea ʻona. Inā he leak, pono e hana i nā hana pilikia kūpono, e like me ke komo ʻana i ka wai me ka desiccant a i ʻole ka hoʻomaʻemaʻe ʻana me kahi adsorbent kemika kūpono.
