Taw qhia
Ethyl 2-mercaptopropionate yog ib qho organic compound. Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm ethyl 2-mercaptopropionate:
Zoo:
- Cov tsos: cov kua tsis muaj xim.
- Odor: Ib qho pungent tsw.
- Soluble: Soluble nyob rau hauv dej thiab organic solvents.
- Ethyl 2-mercaptopropionate yog cov kua qaub tsis muaj zog uas tuaj yeem tsim cov complexes nrog hlau ions.
Siv:
- Nws kuj tseem tuaj yeem siv los ua crosslinker rau hluavtaws polymers thiab roj hmab.
- Ethyl 2-mercaptopropionate tuaj yeem siv los ua cov tshuaj sulfur hauv kev npaj ntawm selenides, thioselenols thiab sulfides.
- Nws kuj tseem siv tau los ua cov hlau yaig inhibitor.
Txoj kev:
- Ethyl 2-mercaptopropionate feem ntau yog npaj los ntawm cov tshuaj tiv thaiv condensation ntawm ethanol thiab mercaptopropionic acid, uas koom nrog kev sib ntxiv ntawm acidic catalyst.
- Cov qauv tshuaj tiv thaiv yog raws li nram no: CH3CH2OH + HSCH2CH2COOH → CH3CH2OSCH2CH2COOH → CH3CH2OSCH2CH2COOCH3.
Cov ntaub ntawv kev nyab xeeb:
- Ethyl 2-mercaptopropionate yuav tsum tau ua tib zoo saib xyuas kom tsis txhob nqus tau, sib cuag nrog daim tawv nqaij thiab qhov muag.
- Hnav cov khoom tiv thaiv tus kheej tsim nyog xws li hnab looj tes, tsom iav, thiab khaub ncaws tiv thaiv thaum siv nws.
- Nws yuav tsum tau muab khaws cia thiab ua haujlwm nyob rau hauv qhov chaw muaj cua zoo, kom deb ntawm qhov hluav taws kub thiab cua sov.
- Ethyl 2-mercaptopropionate yuav tsum khaws cia deb ntawm menyuam yaus thiab tsiaj thiab khaws cia kom zoo.
