Taw qhia
Ethyl isobutyrate. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- Cov tsos: cov kua tsis muaj xim.
- Scent: muaj ib tug fruity aroma.
- Soluble: soluble hauv ethanol, ether thiab ether, insoluble hauv dej.
- Stability: ruaj khov, tab sis tuaj yeem hlawv thaum raug hluav taws kub lossis kub kub.
Siv:
- Kev siv hauv kev lag luam: Siv los ua cov kuab tshuaj hauv cov txheej txheem, dyes, inks, thiab detergents.
Txoj kev:
Kev npaj ntawm ethyl isobutyrate feem ntau txais cov tshuaj tiv thaiv esterification nrog cov kauj ruam hauv qab no:
Ntxiv ib qho nyiaj catalyst (xws li sulfuric acid los yog hydrochloric acid).
React ntawm qhov kub thiab txias rau ib pliag.
Tom qab cov tshuaj tiv thaiv tiav, ethyl isobutyrate yog muab rho tawm los ntawm distillation thiab lwm txoj kev.
Cov ntaub ntawv kev nyab xeeb:
- Ethyl isobutyrate yog flammable thiab yuav tsum tau ceev kom deb ntawm hluav taws kub thiab kub.
- Tsis txhob nqus pa, tiv tauj nrog daim tawv nqaij thiab qhov muag, thiab ua kom muaj cua zoo thaum siv.
- Tsis txhob sib xyaw nrog cov oxidants muaj zog thiab cov kua qaub, uas yuav ua rau muaj kev phom sij txaus ntshai.
- Thaum nqus tau los yog tiv tauj, tawm ntawm qhov chaw tam sim ntawd thiab nrhiav kev kho mob.
