Taw qhia
Propyl acetate (tseem hu ua ethyl propionate) 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 propyl acetate:
Zoo:
- Cov tsos mob: Propyl acetate yog cov kua tsis muaj xim nrog cov txiv hmab txiv ntoo zoo li tsw.
- Solubility: Propyl acetate yog soluble hauv cawv, ethers thiab fatty solvents, thiab yuav luag insoluble hauv dej.
Siv:
- Kev siv hauv kev lag luam: Propyl acetate tuaj yeem siv los ua cov kuab tshuaj thiab feem ntau siv rau hauv kev tsim cov txheej txheem ntawm cov txheej txheem, cov kua roj vanish, cov nplaum, fiberglass, resins, thiab plastics.
Txoj kev:
Propyl acetate feem ntau yog npaj los ntawm reacting ethanol thiab propionate nrog cov kua qaub catalyst. Thaum lub sij hawm cov tshuaj tiv thaiv, ethanol thiab propionate undergo esterification nyob rau hauv lub xub ntiag ntawm ib tug acid catalyst los tsim propyl acetate.
Cov ntaub ntawv kev nyab xeeb:
- Propyl acetate yog cov kua hluav taws kub thiab yuav tsum tau khaws cia kom deb ntawm cov nplaim taws thiab qhov chaw kub.
- Tsis txhob nqus cov pa propyl acetate los yog vapors vim nws tuaj yeem ua rau khaus ua pa thiab qhov muag.
- Thaum tuav cov propyl acetate, hnav hnab looj tes tiv thaiv tsim nyog, tsom iav, thiab khaub ncaws tiv thaiv.
- Propyl acetate yog tshuaj lom thiab yuav tsum tsis txhob noj ncaj qha rau ntawm daim tawv nqaij lossis noj.
