Hoʻolauna
ʻO ka Ethyltriphenylphosphine bromide, i ʻike ʻia ʻo Ph₃PCH₂CH₂CH₃, he hui organophosphorus. ʻO kēia ka hoʻolauna ʻana i nā waiwai, hoʻohana, nā ʻano hoʻomākaukau a me ka ʻike palekana o ka ethyltriphenylphosphine bromide:
ʻAno maikaʻi:
ʻO ka Ethyltriphenylphosphine bromide he kala ʻole i ke aniani melemele māmā a i ʻole ka wai me kahi ʻala benzene ikaika. Hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me nā ethers a me nā hydrocarbons ma ka lumi wela. He haʻahaʻa kona hoʻoheheʻe ʻia ma mua o ka wai.
E hoʻohana:
Loaʻa i ka Ethyltriphenylphosphine bromide ka laulā o nā noi i ka synthesis organik. Hana ia ma ke ʻano he phosphorus reagent no ka hoʻololi nucleophilic o nā mea halogen a me nā hopena hoʻohui nucleophilic o nā pūhui carbonyl. Hiki ke hoʻohana ʻia ma ke ʻano he ligand no ke kemika organometallic a me nā hopena metala-catalyzed hoʻololi.
Hanana:
Hiki ke hoʻomākaukau ʻia ka Ethyltriphenylphosphine bromide e kēia mau hopena:
Ph₃P + BrCH₂CH₂CH₃ → Ph₃PCH₂CH₂CH₃ + HBr
ʻIke palekana:
ʻO ka Ethyltriphenylphosphine bromide he haʻahaʻa haʻahaʻa akā pono e hoʻohana ʻia me ka akahele. ʻO ka hoʻolaha ʻana i ka ethyltriphenylphosphine bromide hiki ke hoʻonāukiuki a me ka pōʻino o ka maka. Pono e mālama pono ʻia, e like me ke komo ʻana i nā mīkina lima a me nā maka aniani, i ka wā e hoʻohana ai, a pono e hōʻoia i ka ea maikaʻi. E hō'ole i ka ho'ohu 'ana i kona mahu a i 'ole e pili ana i ka 'ili a me nā maka i ka wā o ka hana.
