Hoʻolauna

ʻO ka 2-Bromo-5-chlorobenzoic acid he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka pūhui:

 

ʻAno maikaʻi:

ʻO ka 2-Bromo-5-chlorobenzoic acid he hui paʻa. Lawe ʻo ia i ke ʻano o nā kristal keʻokeʻo a melemele paha i ka lumi wela. Loaʻa iā ia ke kūpaʻa wela maikaʻi a hiki ke noho paʻa i nā wela kiʻekiʻe. He kiʻekiʻe ka solubility o ka hui i nā mea hoʻoheheʻe organik.

 

E hoʻohana:

Hoʻohana pinepine ʻia ʻo 2-Bromo-5-chlorobenzoic acid ma ke ʻano he koʻikoʻi koʻikoʻi koʻikoʻi i ka synthesis organik.

 

Hanana:

ʻO ka 2-Bromo-5-chlorobenzoic acid ka mea maʻamau i hoʻomākaukau ʻia e ka bromination a me ka chlorination o ka waikawa benzoic. Hoʻopili mua ka ʻakika Benzoic me ka bromine a me ka waikawa sulfurous e hana i ka bromine benzoate, a laila hana me ka ferric chloride e loaʻa ai ka 2-bromo-5-chlorobenzoic acid.

 

ʻIke palekana:

ʻO ka 2-Bromo-5-chlorobenzoic acid he mea hoʻohuihui kino e hoʻopilikia ai i ke kanaka a me ke kaiapuni. Hiki i ka ʻike ʻana a i ʻole ka inhalation o ka hui ke hoʻonāukiuki i ka maka, ka ʻili, a me ka ʻōpū hanu. Pono e ʻaʻahu ʻia nā mea pale kūpono e like me nā mīkina lima, nā pale maka, a me nā maka pale i ka wā e hana ai. Pono e hoʻohana ʻia a mālama ʻia i loko o kahi wahi e hoʻoheheʻe maikaʻi ʻia, ma kahi mamao aku i ke ahi a me nā mea ʻona. Pono e mālama koke ʻia kēlā me kēia hoʻopili a ʻai ʻole paha a loaʻa ka ʻōlelo aʻoaʻo olakino. Pono e hahai ʻia nā kaʻina hana palekana piha i ka wā e lawelawe ai i kēia pūhui.
