Taw qhia
Butyl acetate, tseem hu ua butyl acetate, yog cov kua tsis muaj xim nrog cov ntxhiab tsw uas tsis muaj dej-soluble. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm butyl acetate:
Zoo:
- Cov tsos mob: tsis muaj xim pob tshab kua
Cov mis mos molecular: C6H12O2
- Molecular Luj: 116.16
- Ceev: 0.88 g / mL ntawm 25 ° C (lit.)
- Kub Point: 124-126 ° C (lit.)
Melting Point: -78 ° C (lit.)
- Solubility: me ntsis soluble hauv dej, soluble nyob rau hauv ntau cov organic solvents
Siv:
- Cov ntawv thov kev lag luam: Butyl acetate yog ib qho tseem ceeb ntawm cov organic hnyav, uas yog siv dav hauv cov xim, txheej, kua nplaum, inks thiab lwm yam kev lag luam.
- Cov tshuaj tiv thaiv tshuaj: Nws kuj tuaj yeem siv los ua substrate thiab hnyav hauv cov organic synthesis rau kev npaj ntawm lwm cov organic tebchaw.
Txoj kev:
Kev npaj ntawm butyl acetate feem ntau yog tau los ntawm esterification ntawm acetic acid thiab butanol, uas yuav tsum tau siv cov kua qaub catalysts xws li sulfuric acid los yog phosphoric acid.
Cov ntaub ntawv kev nyab xeeb:
- Tsis txhob nqus pa, tiv thaiv daim tawv nqaij thiab noj, thiab hnav cov hnab looj tes tiv thaiv, tsom iav thiab daim npog ntsej muag thaum siv.
- Siv nyob rau hauv qhov chaw uas muaj qhov cua zoo thiab tsis txhob cuam tshuam ntev rau qhov siab siab.
- Khaws kom deb ntawm qhov hluav taws kub thiab oxidants kom lawv ruaj khov.
