Intshayelelo

I-3-Bromopropyne, eyaziwa ngokuba yi-1-bromo-2-propyne, i-organic compound. Oku kulandelayo sisingeniso esifutshane kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:

 

Umgangatho:

- Inobunzima obuphantsi, kunye nexabiso malunga ne-1.31 g / mL.

- I-3-Bropropyne inevumba elibi.

-Inokunyibilika kwezinye izinyibilikisi eziphilayo ezifana ne-ethanol kunye ne-ether.

 

Sebenzisa:

- I-3-Broproyne isetyenziswa kakhulu njenge-reagent kwi-organic synthesis reactions, umzekelo inokuthatha inxaxheba kwi-metal-catalyzed cross-coupling reactions for synthesis of organic compounds.

- Isenokusetyenziswa njengesixhobo sokuqala iialkynes, umz. ukudibanisa iialkynes okanye ezinye iialkynes ezisebenzayo.

 

Indlela:

- I-3-Bromopropyne inokufumaneka ngokuphendula kwe-bromoacetylene kunye ne-ethyl chloride phantsi kweemeko ze-alkaline.

- Oku kwenziwa ngokuxuba i-bromoacetylene kunye ne-ethyl chloride kunye nokongeza umlinganiselo othile we-alkali (njenge-sodium carbonate okanye i-sodium bicarbonate).

- Ekupheleni kokuphendula, i-3-bromopropynne ecocekileyo ifunyenwe nge-distillation kunye nokucoca.

 

Ulwazi ngoKhuseleko:

- I-3-i-Bropropyne yinto enetyhefu kunye nento ecaphukisayo efuna izixhobo ezifanelekileyo zokukhusela (i-PPE) ukuba zigqitywe xa usebenza.

- Kufuneka igweme ukudibana ne-oxidants, i-alkalis eyomeleleyo, kunye ne-acids eqinile ukuphepha ukuphendula okuyingozi.

- Ukuthobela iinkqubo ezifanelekileyo zokusebenza zokhuseleko ngexesha lokusetyenziswa kunye nokugcinwa.

- Xa uphethe i-3-bromopropyne, qinisekisa ukungena komoya kakuhle kwaye ugweme ukuphefumla imiphunga yayo okanye ukudibana nolusu kunye namehlo.
