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 ugweme ukudibanisa nee-oxidants, i-alkalis eyomeleleyo, kunye ne-acids ezomeleleyo 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.

Ngaphambili: I-3-Bromopropionitrile(CAS#2417-90-5)

Okulandelayo: 3-Bromopropionic acid(CAS#590-92-1)
