Taw qhia
Tom ntej: Methyl 2-methylbutyrate 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 mob: Methyl 2-methylbutyrate yog cov kua tsis muaj xim nrog cov ntxhiab tsw.
- Solubility: Methyl 2-methylbutyrate yog soluble hauv cawv thiab ethers, tab sis insoluble hauv dej.
Siv:
- Muaj kev siv: Methyl 2-methylbutyrate feem ntau yog siv los ua cov kuab tshuaj hauv kev tsim cov yas, resins, coatings, thiab lwm yam.
- Kev siv tshuaj lom neeg: Nws kuj yog siv los ua cov tshuaj reagent hauv cov organic synthesis cov tshuaj tiv thaiv.
Txoj kev:
Kev npaj ntawm methyl 2-methylbutyrate feem ntau ua tiav los ntawm acid-catalyzed esterification cov tshuaj tiv thaiv. Tshwj xeeb, ethanol yog reacted nrog isobutyric acid, thiab nyob rau hauv qhov tsim nyog cov tshuaj tiv thaiv, xws li ntxiv sulfuric acid catalyst thiab kub tswj, cov tshuaj tiv thaiv yields methyl 2-methylbutyrate.
Cov ntaub ntawv kev nyab xeeb:
- Methyl 2-methylbutyrate yog cov kua hluav taws xob uas tuaj yeem tsim cov pa phem ntawm qhov kub thiab txias.
- Kev saib xyuas yuav tsum tau ua kom tsis txhob muaj kev sib cuag nrog cov oxidizing muaj zog thaum siv lossis khaws cia.
- Kev sib cuag nrog daim tawv nqaij yuav ua rau khaus thiab ua xua, hnab looj tes tiv thaiv, tsom iav thiab khaub ncaws tiv thaiv yuav tsum hnav thaum tuav.
- Yog tias methyl 2-methylbutyrate tau nqus los yog nqus tau, txav mus rau qhov chaw muaj cua tam sim ntawd thiab nrhiav kev kho mob sai li sai tau.
