Taw qhia
3- (methylthio) propionaldehyde yog ib qho organic compound,
Zoo:
- Cov tsos mob: 3-(methylthio) propionaldehyde yog xim tsis muaj xim rau cov kua daj daj.
- ntxhiab tsw: muaj pungent thiab pungent tsw ntawm leej faj.
- Solubility: Soluble nyob rau hauv dej thiab organic solvents.
Siv:
- 3-(methylthio) propionaldehyde yog siv los ua ib qho tseem ceeb reagent hauv organic synthesis.
Txoj kev:
- 3- (methylthio) propionaldehyde tuaj yeem npaj los ntawm ntau txoj hauv kev sib xyaw. Piv txwv li, nws tuaj yeem tau los ntawm malonitrile los ntawm kev ua haujlwm nrog hydrogen sulfide thiab tom qab ntawd los ntawm thionylation chloride. Qee lwm txoj hauv kev suav nrog kev siv thionyl chloride thiab sodium methosulfate cov tshuaj tiv thaiv, sodium ethyl sulfate thiab acetic acid tshuaj, thiab lwm yam.
Cov ntaub ntawv kev nyab xeeb:
- 3-(Methylthio) propionaldehyde yog nplaim taws kub thiab qhib nplaim taws, thiab cov pa phem tuaj yeem tsim tau thaum raug hluav taws kub.
- Nws yog ib qho ua rau khaus khaus uas yuav ua rau khaus qhov muag, tawv nqaij, thiab ua pa.
- Hnav cov cuab yeej tiv thaiv tsim nyog xws li lub tshuab ua pa, tiv thaiv qhov muag thiab hnab looj tes thaum siv.
- Thaum khaws cia, nws yuav tsum muab cia rau hauv qhov chaw txias, qhov cua, kom deb ntawm hluav taws thiab oxidants.
- Kev saib xyuas yuav tsum tau ua kom tsis txhob muaj kev sib cuag nrog cov oxidants muaj zog, muaj zog acids thiab muaj zog alkalis thaum ua haujlwm kom tsis txhob muaj kev phom sij txaus ntshai.
