Intshayelelo emfutshane
I-3-butyne-2-ol, eyaziwa ngokuba yi-butynol, i-organic compound. Oku kulandelayo sintshayelelo kwiipropati zayo, ukusetyenziswa, iindlela zokuvelisa kunye nolwazi lokhuseleko:
Umgangatho:
- Imbonakalo: 3-butyn-2-ol lulwelo olungenambala.
- Ukunyibilika: Kunyibilika kwii-alcohols ezingasebenziyo kunye ne-ether, ngelixa ukunyibilika kwayo emanzini kuphantsi.
- Ivumba: 3-butyn-2-ol inevumba elibi.
Sebenzisa:
- I-Chemical synthesis: inokusetyenziswa njengendawo ephakathi kwi-organic synthesis ukulungiselela ezinye iikhompawundi eziphilayo.
- I-Catalyst: I-3-butyn-2-ol ingasetyenziswa njenge-catalyst yezinye ii-catalyzed reactions.
- Isinyibilikisi: Ngenxa yokunyibilika kwayo okulungileyo kunye netyhefu ephantsi ngokwentelekiso, inokusetyenziswa njengesinyibilikisi.
Indlela:
- 3-Butyn-2-ol inokulungiswa ngokusabela kwe-butyne kunye ne-ether. Ukusabela kuqhutyelwa phambi kotywala kwaye kuqhutyelwa kumaqondo aphantsi.
- Enye indlela yokulungisa kukusabela kwe-butyne kunye ne-acetaldehyde. Oku kusabela kufuneka kuqhutywe phantsi kweemeko ze-acidic.
Ulwazi ngoKhuseleko:
- I-3-Butyn-2-ol lulwelo olunokutsha kwaye kufuneka lugcinwe kude namadangatye avulekileyo kunye namaqondo obushushu aphezulu.
- Thatha amanyathelo okhuseleko xa usebenzisa iiglasi ezikhuselayo, kubandakanywa iiglasi zokukhusela kunye neeglavu.
- Xa udibana nesikhumba okanye amehlo, hlambulula ngokukhawuleza ngamanzi amaninzi.
• Kuphephe ukuphefumla umphunga kwaye uwusebenzise kwindawo engena umoya.
- Ukulahlwa kwenkunkuma kufuneka kuhambelane nemigaqo yendalo esingqongileyo.
