Taw qhia
Ethyl methylthioacetate hmoov. Cov hauv qab no yog kev qhia txog qhov xwm txheej, kev siv, kev tsim khoom, thiab cov ntaub ntawv kev nyab xeeb ntawm MTEE:
Zoo:
- Cov tsos mob: Ethyl methyl thioacetate yog cov kua tsis muaj xim lossis daj daj.
- Cov ntxhiab tsw: muaj ntxhiab tsw tshwj xeeb.
- Solubility: Soluble hauv dej thiab cov organic solvents xws li cawv, ethers, thiab aromatics.
Siv:
Ethyl methyl thioacetate yog dav siv hauv cov organic synthesis:
- Raws li ib tug reagent rau active methyl sulfide los yog methyl sulfide ions, nws koom nyob rau hauv ntau yam organic synthesis tshuaj.
Txoj kev:
Ethyl methylthioacetate feem ntau tuaj yeem npaj los ntawm cov hauv qab no:
- Thioacetic acid (CH3COSH) yog reacted nrog ethanol (C2H5OH) thiab dehydrated kom tau ethyl methylthioacetate.
Cov ntaub ntawv kev nyab xeeb:
- Ethyl methylthioacetate yuav tsum hnav nrog cov tsom iav tiv thaiv, hnab looj tes thiab cov khaub ncaws tiv thaiv kom tsis txhob muaj kev sib cuag ncaj qha rau ntawm daim tawv nqaij thiab qhov muag.
- Tsis txhob nqus nws cov vapors thiab tswj qhov cua kom zoo thaum ua haujlwm.
- Ua tib zoo saib xyuas kev tiv thaiv hluav taws thiab hluav taws xob zoo li qub thaum siv. Tsis txhob raug tshav kub, sparks, qhib nplaim taws, thiab haus luam yeeb.
- Khaws kaw kom nruj, kom deb ntawm qhov hluav taws kub thiab kub, thiab tsis txhob raug tshav ntuj.
