Kev taw qhia luv luv
3-butyne-2-ol, tseem hu ua butynol, yog cov organic compound. Cov hauv qab no yog kev qhia txog nws cov khoom, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- Cov tsos mob: 3-butyn-2-ol yog cov kua tsis muaj xim.
- Solubility: Nws yog soluble hauv anhydrous alcohols thiab ether, thaum nws solubility hauv dej kuj tsawg.
- Cov ntxhiab tsw: 3-butyn-2-ol muaj ntxhiab tsw ntxhiab.
Siv:
- Chemical synthesis: nws tuaj yeem siv los ua ib qho nruab nrab hauv cov organic synthesis rau kev npaj ntawm lwm cov organic tebchaw.
- Catalyst: 3-butyn-2-ol tuaj yeem siv los ua cov catalyst rau qee qhov kev cuam tshuam catalyzed.
- Cov kuab tshuaj: Vim nws zoo solubility thiab tsis tshua muaj toxicity, nws tuaj yeem siv los ua cov kuab tshuaj.
Txoj kev:
- 3-Butyn-2-ol tuaj yeem npaj tau los ntawm cov tshuaj tiv thaiv ntawm butyne thiab ether. Cov tshuaj tiv thaiv yog nqa tawm nyob rau hauv lub xub ntiag ntawm cawv thiab yog nqa tawm nyob rau hauv qis kub.
- Lwm txoj kev npaj yog los ntawm cov tshuaj tiv thaiv ntawm butyne thiab acetaldehyde. Cov tshuaj no yuav tsum tau ua nyob rau hauv acidic tej yam kev mob.
Cov ntaub ntawv kev nyab xeeb:
- 3-Butyn-2-ol yog cov kua ua kua thiab yuav tsum tau ceev kom deb ntawm cov nplaim taws thiab qhov kub thiab txias.
- Ceev faj thaum siv nrog cov iav tiv thaiv, nrog rau cov iav tiv thaiv thiab hnab looj tes.
- Thaum ntsib daim tawv nqaij lossis qhov muag, yaug tam sim ntawd nrog dej ntau.
- Tsis txhob nqus nws cov vapors thiab siv rau hauv qhov chaw uas muaj cua zoo.
- Kev pov tseg pov tseg yuav tsum ua raws li cov cai hauv cheeb tsam ib puag ncig.
