Hoʻolauna

ʻO 1-Bromo-2-butyne he mea hoʻohuihui. ʻO kēia ka hoʻolauna ʻana i kona ʻano, hoʻohana, ʻano hoʻomākaukau a me ka ʻike palekana:

 

Nā waiwai: 1-Bromo-2-butyne he wai waihoʻoluʻu a ʻeleʻele melemele me kahi ʻala ʻokoʻa. ʻAʻole hiki ke hoʻoheheʻe ʻia i loko o ka wai akā hiki ke hoʻoheheʻe ʻia i loko o nā mea hoʻoheheʻe organik e like me ka ethers a me ka waiʻona. He haʻahaʻa kona wahi hoʻā a hiki ke hoʻopau ʻia.

 

Hoʻohana: Hoʻohana pinepine ʻia ʻo 1-Bromo-2-butyne ma ke ʻano he reagent i nā hopena synthesis organik. Hiki ke hoʻohana ʻia i ka synthesis o nā ʻano mea like ʻole e like me nā alkynes, haloalkynes, a me nā pūhui organometallic. Hiki ke hoʻohana ʻia e like me ka solvent organik a me ka polymer additive.

 

ʻO ke ʻano o ka hoʻomākaukau ʻana: ʻO ka hoʻomākaukau ʻana o 1-bromo-2-butyne i loaʻa nui ʻia e ka bromide 2-butyne. Hoʻohui mua ʻia ʻo Bromine i ka mea hoʻoheheʻe ethanol, a ukali ʻia e kahi hopena alkaline no ka hoʻopili ʻana i ka hopena. I ka mahana kūpono a me ka manawa pane, hoʻokumu ʻia ka 1-bromo-2-butyne.

 

ʻIke palekana: ʻO 1-Bromo-2-butyne kahi hui weliweli a pono e mālama pono ʻia. He mea hoʻonāukiuki a ʻona a hiki ke hōʻeha i ka maka a me ka ʻili. I ka wā e hoʻohana ʻia ai, pono e hoʻohana ʻia nā mīkina lima pale, nā maka aniani a me nā lole pale. E hana i loko o kahi kaiapuni maikaʻi a pale i ka inha ʻana i nā mahu. I ka hihia o ka ʻai ʻana a i ʻole ka inhalation, pono e ʻimi koke ʻia ke kōkua olakino.
