Taw qhia
Ethyl 2-methylbutyrate (tseem hu ua 2-methylbutyl acetate) yog cov organic compound. Cov hauv qab no yog cov lus qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab kev nyab xeeb cov ntaub ntawv:
Zoo:
- Cov tsos mob: Ethyl 2-methylbutyrate yog cov kua tsis muaj xim.
- Smell: Ib tug tsw nrog ib tug fruity saj.
- Solubility: Ethyl 2-methylbutyrate yog miscible nrog ntau cov organic solvents xws li cawv thiab ethers, thiab yog insoluble hauv dej.
Siv:
- Ethyl 2-methylbutyrate feem ntau yog siv los ua cov kuab tshuaj thiab siv dav hauv cov chaw kuaj tshuaj thiab kev tsim khoom lag luam.
- Hauv cov organic synthesis, nws tuaj yeem siv los ua cov tshuaj tiv thaiv hnyav lossis cov kuab tshuaj extraction.
Txoj kev:
- Ethyl 2-methylbutyrate feem ntau yog npaj los ntawm esterification. Ib txoj hauv kev yog esterify methanol thiab 2-methylbutyric acid los tsim methyl 2-methylbutyrate, thiab tom qab ntawd ua rau methyl 2-methylbutyrate nrog ethanol los ntawm cov tshuaj tiv thaiv acid-catalyzed kom tau ethyl 2-methylbutyrate.
Cov ntaub ntawv kev nyab xeeb:
- Ethyl 2-methylbutyrate feem ntau muaj kev nyab xeeb nyob rau hauv ib txwm siv, tab sis tseem yuav tsum tau saib xyuas kom tsis txhob sib cuag nrog daim tawv nqaij, qhov muag, thiab nqus tau pa. Cov hnab looj tes tiv thaiv, tsom iav, thiab lub qhov ncauj qhov ntswg yuav tsum hnav, thiab nco ntsoov ua haujlwm hauv qhov chaw muaj cua zoo.
-Thaum sib cuag nrog daim tawv nqaij, yaug tam sim ntawd nrog dej ntau.
-Yog nqus tau los yog nqos, cia tus neeg mob nyob rau hauv qhov chaw uas muaj cua zoo thiab nrhiav kev kho mob tam sim ntawd. Kev ntuav yuav tsum tsis txhob raug ntxias vim nws yuav ua rau cov tsos mob hnyav dua.
- Ethyl 2-methylbutyrate yog cov kua ua kua thiab yuav tsum tau zam los ntawm kev sib cuag nrog cov nplaim taws qhib thiab kub.
- Thaum lub sijhawm khaws cia, nws yuav tsum muab cia rau hauv qhov tsaus ntuj, txias, qhuav, qhov cua zoo, kom deb ntawm oxidants thiab hluav taws kub.
