Hoʻolauna

ʻO ka Bromobenzene kahi pūhui kino. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka bromobenzene:

 

ʻAno maikaʻi:

1. He wai waihoʻoluʻu ʻole ia, ʻaʻole maopopo a hiki i ka melemele māmā ma ke ana wela.

2. He ʻala ʻokoʻa kona, a ʻaʻole hiki ke hoʻoheheʻe ʻia me ka wai, a hiki ke hui pū me nā mea hoʻoheheʻe kūlohelohe e like me ka waiʻona a me ka etera.

3. ʻO ka Bromobenzene kahi pūhui hydrophobic e hiki ke hoʻoheheʻe ʻia e ka oxygen a me ka ozone.

 

E hoʻohana:

1. Hoʻohana nui ʻia ia i nā hopena synthesis organik, e like me kahi reagent koʻikoʻi a me waena.

2. Hiki ke hoʻohana 'ia e like me ka lapalapa ahi i ka hana 'ana i ka plastics, ka uhi a me ka uila.

 

Hanana:

Hoʻomākaukau nui ʻia ʻo Bromobenzene e ke ʻano ferromide. Hoʻopili mua ʻia ka hao me ka bromine e hana i ka bromide ferric, a laila hoʻopili ʻia ka hao bromide me benzene e lilo i bromobenzene. ʻO nā kūlana o ka hopena he mea maʻamau ka hopena wela, a pono e hoʻolohe i ka palekana i ka wā e hoʻokōʻia ai ka hopena.

 

ʻIke palekana:

1. He kiʻekiʻe toxicity a me ka corrosiveness.

2. ʻO ka hoʻolaha ʻana i ka bromobenzene hiki ke hoʻonāukiuki i nā maka, ka ʻili a me ka ʻāpana hanu o ke kino o ke kanaka, a hiki i ka make.

3. I ka wā e hoʻohana ai i ka bromobenzene, pono e hoʻohana i nā mea pale kūpono, e like me nā mīkina lima, nā aniani palekana a me nā pale pale.

4. A e hōʻoia e hoʻohana ʻia ia i loko o kahi kaiapuni maikaʻi e pale aku ai i ka pilina lōʻihi a i ʻole inhalation.

5. Inā pili ʻoe i ka bromobenzene, pono ʻoe e holoi koke i ka ʻāpana me ka wai nui a ʻimi i ke kōkua olakino.
