Hoʻolauna

ʻO 3-Bromopropyne, ʻike ʻia hoʻi ʻo 1-bromo-2-propyne, he mea hoʻohuihui. ʻO kēia ka hoʻolauna pōkole i kāna mau waiwai, hoʻohana, hana hana a me ka ʻike palekana:

 

ʻAno maikaʻi:

- He haʻahaʻa haʻahaʻa kona, me ka waiwai ma kahi o 1.31 g/mL.

- 3-He pilau ko Bropropyne.

- Hiki ke hoʻoheheʻe ʻia i loko o kekahi mau mea hoʻoheheʻe kūlohelohe e like me ka ethanol a me ka etera.

 

E hoʻohana:

- Hoʻohana nui ʻia ʻo 3-Broproyne ma ke ʻano he reagent i nā hopena synthesis organik, no ka laʻana hiki iā ia ke komo i nā hopena cross-coupling metal-catalyzed no ka synthesis o nā pūhui organik.

- Hiki ke hoʻohana ʻia ma ke ʻano he mea hoʻomaka no nā alkynes, e laʻa no ka synthesis o nā alkynes a i ʻole nā ​​​​alkynes i hana ʻia.

 

Hanana:

- Hiki ke loaʻa ka 3-Bromopropyne ma ka hopena o ka bromoacetylene a me ka ethyl chloride ma lalo o nā kūlana alkaline.

- Hana ʻia kēia ma ka hui ʻana i ka bromoacetylene a me ka ethyl chloride a hoʻohui i kahi nui o ka alkali (e like me ka sodium carbonate a i ʻole ka sodium bicarbonate).

- I ka hopena o ka hopena, loaʻa ka 3-bromopropynne maʻemaʻe e ka distillation a me ka hoʻomaʻemaʻe.

 

ʻIke palekana:

- ʻO 3-Bropropyne kahi mea ʻawaʻawa a hoʻonāukiuki e pono ai e hoʻohana pono i nā lako pale pilikino (PPE) i ka wā e hana ai.

- Pono ia e pale aku i ka hoʻopili ʻana me nā oxidants, nā alkali ikaika, a me nā ʻakika ikaika e pale aku i nā hopena pōʻino.

- E mālama pono i nā kaʻina hana palekana i ka wā e hoʻohana ai a mālama.

- I ka lawelawe ʻana i ka 3-bromopropyne, e hōʻoia i ka ea maikaʻi a pale i ka hoʻohu ʻana i kona mau mahu a i ʻole e pili ana i ka ʻili a me nā maka.
