Intshayelelo
I-2-butynyl-1-ol, eyaziwa ngokuba yi-butynol, i-organic compound. Oku kulandelayo kukwazisa kwiipropati, ukusetyenziswa, iindlela zokulungiselela kunye nolwazi lokhuseleko lwe-2-butyn-1-ol:
Iimpawu: Lulwelo olungenambala olunevumba elikhethekileyo elihlabayo.
- I-2-Butyn-1-ol iyanyibilika emanzini kunye nezinyibilikisi ezininzi ze-organic ezifana ne-ethanol kunye ne-ether.
- Yikhompawundi yotywala kunye namaqela asebenzayo e-alkyne aneempawu ezithile zeekhemikhali ze-alcohol kunye ne-alkynes.
Sebenzisa:
- I-2-butyn-1-ol isetyenziswa ngokubanzi kwi-organic synthesis njenge-reaction intermediate okanye i-reagent. Ingasetyenziswa njengento yokuqala, i-solvent, okanye i-catalyst ye-synthesis ye-organic compounds.
- Isenokusetyenziswa ekulungiseleleni ezinye iikhompawundi ezifanayo ezifana ne-ethers, ii-ketones, kunye ne-etherketones.
Indlela:
- I-2-Butyno-1-ol inokulungiswa ngokusabela kwe-hydrogenated acetone alcohol kunye ne-chloroform.
- Enye indlela eqhelekileyo yokulungiswa kukudibanisa i-ethyl mercaptan kunye ne-acetone phambi kwe-amino catalyst, kwaye emva koko ufumane i-2-butyn-1-ol ngokudibanisa i-mercury chloride.
Ulwazi ngoKhuseleko:
- 2-Butyn-1-ol yinto ecaphukisayo enokubangela ukucaphuka kunye nomonakalo kwamehlo, ulusu, kunye nendlela yokuphefumla.
- Izixhobo ezifanelekileyo zokukhusela ezifana neeglavu zokukhusela kunye neglavu kufuneka zinxitywe xa uphathwa.
- Ikhompawundi ineempembelelo ezilinganiselweyo kokusingqongileyo, kodwa kufuneka kuthatyathwe ukhathalelo lokuthobela imigaqo efanelekileyo yokusingqongileyo xa iphathwa kwaye ichithwa.
