Hoʻolauna

ʻO ka 2,4-Difluorobromobenzene kahi hui kino. He wai waihoʻoluʻu ʻole a ʻeleʻele melemele me ke ʻala ʻala. Eia ka wehewehe kikoʻī o nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o 2,4-difluorobromobenzene:

 

ʻAno maikaʻi:

ʻO ka 2,4-Difluorobromobenzene kahi mea hiki ke hana i nā mea pahū a pahū paha me ka ea. He mea ino ia i kekahi mau metala.

 

E hoʻohana:

Hoʻohana nui ʻia ka 2,4-Difluorobromobenzene ma ke ʻano he waena i ka synthesis organik. Ma ke kahua o nā pesticides, hoʻohana ʻia ia e hana i nā insecticides a me nā herbicides.

 

Hanana:

ʻO 2,4-Difluorobromobenzene ka mea maʻamau i hoʻomākaukau ʻia e ka pane hoʻololi. ʻO kahi ʻano hoʻomākaukau maʻamau ka hoʻopili ʻana i ka bromobenzene me ka fluoride potassium ma lalo o nā kūlana acidic e hoʻohua ai i ka 2,4-dibromobenzene, a laila fluorinate i mua o kahi mea hana fluorinating e loaʻa ai ka 2,4-difluorobromobenzene.

 

ʻIke palekana:

ʻO 2,4-Difluorobromobenzene kahi mea olaola me kekahi mea ʻona. He hopena hoʻonāukiuki kona i ka ʻili, nā maka, a me nā mucous membrane a pono e holoi ʻia me ka wai ma hope koke o ka hoʻopili ʻana. Pono e pale ʻia ka inhalation o kona mau mahu i ka wā o ka hoʻohana ʻana a pono e hōʻoia i ka hoʻoheheʻe ʻana. I ka wā o ka mālama ʻana a me ka mālama ʻana, pono e mālama i ka pale ʻana i ka uila a me ka uila. Pono e hahai ʻia nā kaʻina hana palekana kūpono a pono e hoʻohana i nā lako pale kūpono. I ka lawelawe ʻana i ka 2,4-difluorobromobenzene, pono e mālama ʻia nā hoʻoponopono kūloko a pono e hoʻolei pono ʻia ka ʻōpala.
