Taw qhia

3-Bromopropyne, tseem hu ua 1-bromo-2-propyne, yog cov organic compound. Cov hauv qab no yog cov lus qhia luv luv rau nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:

 

Zoo:

- Nws muaj qhov ntom ntom ntom, nrog tus nqi ntawm 1.31 g / mL.

- 3-Bropropyne muaj ntxhiab tsw.

- Nws tuaj yeem soluble hauv qee cov kuab tshuaj organic xws li ethanol thiab ether.

 

Siv:

- 3-Broproyne feem ntau yog siv los ua ib qho reagent nyob rau hauv cov organic synthesis cov tshuaj tiv thaiv, piv txwv li nws muaj peev xwm koom nyob rau hauv cov hlau-catalyzed ntoo khaub lig-coupling tshua rau cov synthesis ntawm cov organic tebchaw.

- Nws kuj tuaj yeem siv los ua cov khoom pib rau alkynes, piv txwv li rau kev sib txuas ntawm alkynes lossis lwm yam kev ua haujlwm alkynes.

 

Txoj kev:

- 3-Bromopropyne tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm bromoacetylene thiab ethyl chloride nyob rau hauv alkaline tej yam kev mob.

- Qhov no yog ua los ntawm kev sib xyaw bromoacetylene thiab ethyl chloride thiab ntxiv qee qhov alkali (xws li sodium carbonate lossis sodium bicarbonate).

- Thaum kawg ntawm cov tshuaj tiv thaiv, ntshiab 3-bromopropynne yog tau los ntawm distillation thiab purification.

 

Cov ntaub ntawv kev nyab xeeb:

- 3-Bropropyne yog cov tshuaj lom thiab ua rau khaus uas yuav tsum tau siv cov cuab yeej tiv thaiv tus kheej (PPE) kom zoo thaum ua haujlwm.

- Nws yuav tsum tsis txhob sib cuag nrog oxidants, muaj zog alkalis, thiab muaj zog acids kom tsis txhob muaj kev phom sij txaus ntshai.

- Ua raws li cov txheej txheem kev nyab xeeb uas cuam tshuam thaum siv thiab khaws cia.

- Thaum tuav 3-bromopropyne, xyuas kom muaj cua zoo thiab tsis txhob nqus nws cov vapors los yog nkag mus rau ntawm daim tawv nqaij thiab qhov muag.
