Sumo pfupi
3-butyne-2-ol, inozivikanwawo sebutynol, isanganiswa yeorganic. Iyi inotevera sumo yezvivakwa zvayo, kushandiswa, nzira dzekugadzira uye ruzivo rwekuchengetedza:

Hunhu:
- Kuonekwa: 3-butyn-2-ol imvura isina ruvara.
- Solubility: Inonyungudika muanhydrous alcohols uye ether, nepo kunyungudika kwayo mumvura kwakadzikira.
- Kunhuwa: 3-butyn-2-ol ine kunhuhwirira kunopinza.

Shandisa:
-Kemikari synthesis: inogona kushandiswa seyepakati mune organic synthesis yekugadzirira mamwe organic komisheni.
- Catalyst: 3-butyn-2-ol inogona kushandiswa sechinhu chinokonzeresa kune mamwe maitiro anokonzeresa.
- Solvent: Nekuda kwekunyungudika kwayo uye kuderera kwehupfu, inogona kushandiswa sechinhu chinonyungudutsa.

Nzira:
- 3-Butyn-2-ol inogona kugadzirirwa nekuita kwebutyne uye ether. Mhedzisiro inoitwa pamberi pedoro uye inoitwa pakudziya kwakadzika.
- Imwe nzira yekugadzirira ndeyekuita kwebutyne uye acetaldehyde. Kuita uku kunofanirwa kuitwa pasi pemamiriro e acidic.

Zvekuchengetedza
- 3-Butyn-2-ol imvura inopisa uye inofanira kuchengetedzwa kure nemirazvo yakazaruka uye kupisa kwakanyanya.
- Tora chenjedzo paunenge uchishandisa nemagirazi ekudzivirira, kusanganisira magirazi ekudzivirira uye magurovhosi.
- Kana uchisangana neganda kana maziso, sukurudza nekukurumidza nemvura yakawanda.
- Dzivisa kufemesa mhute dzayo uye shandisa munzvimbo ine mhepo inofefetera.
- Kurasa tsvina kunofanirwa kuenderana nemirairo yenharaunda yezvakatipoteredza.
