Taw qhia
β-butanone, tseem hu ua β-Turkone, yog cov organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm β-butanone:
Zoo:
- β-MEK yog cov kua tsis muaj xim uas muaj ntxhiab tsw tshwj xeeb.
- Lub hom β-butanone yog tsim ntawm dimers thiab polymers los ntawm hydrogen bonds nyob rau hauv lub molecule, uas yuav ua tau rau kev hloov nyob rau hauv nws cov khoom.
Siv:
- β-MEKT yog siv dav hauv kev lag luam tshuaj raws li cov kuab tshuaj, reactant thiab nruab nrab.
- Nws kuj yog siv los ua cov kuab tshuaj rau cov xim thiab cov nplaum thiab hauv kev lag luam luam ntawv thiab dyeing.
Txoj kev:
- β-MEKONE tuaj yeem ua ke los ntawm ketone deterioration cov tshuaj tiv thaiv. Cov tshuaj tiv thaiv no yog react butanol nrog ammonium chloride thiab penta [2,2,2] oxide los tsim β-butanone ntawm qhov kub thiab txias.
Cov ntaub ntawv kev nyab xeeb:
- β-MEKT muaj toxicity tsawg tab sis tseem yuav tsum tau saib xyuas.
- Nws yog cov kua dej uas muaj hluav taws kub thiab yuav tsum tau khaws cia kom deb ntawm cov nplaim taws thiab qhov chaw kub.
- Kev ua pa zoo yuav tsum tau khaws cia thaum tuav lossis khaws cia β-butanone.
- Kev saib xyuas yuav tsum tau ua kom tsis txhob muaj kev sib cuag ncaj qha rau ntawm daim tawv nqaij thiab qhov muag thaum siv.
