Taw qhia
S-methyl thioacetate, tseem hu ua methyl thioacetate.
Zoo:
S-methyl thioacetate yog cov kua xim tsis muaj xim nrog cov ntxhiab tsw muaj zog. Nws yog soluble hauv ntau cov kuab tshuaj organic xws li cawv, ethers, thiab aromatics.
Siv:
S-methyl thioacetate feem ntau yog siv rau vulcanization thiab esterification cov tshuaj tiv thaiv hauv cov organic synthesis.
Txoj kev:
S-methyl thioacetate tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm methyl acetate nrog sulfur nyob rau hauv alkaline tej yam kev mob. Cov kauj ruam tshwj xeeb yog los ua cov tshuaj methyl acetate nrog cov tshuaj alkaline sulfur, thiab tom qab ntawd distilled thiab ntxuav cov khoom kom tau txais cov khoom.
Cov ntaub ntawv kev nyab xeeb:
S-methyl thioacetate yog khaus khaus thiab yuav tsum tsis txhob kov ncaj qha rau ntawm daim tawv nqaij thiab qhov muag. Thaum siv, yuav tsum tau saib xyuas kev tiv thaiv, xws li hnav tsom iav thiab hnab looj tes. Thaum khaws cia thiab tuav cov khoom sib xyaw no, ib puag ncig zoo-ventilated yuav tsum tau khaws cia kom deb ntawm qhov hluav taws kub thiab oxidants. Nyob rau hauv cov ntaub ntawv ntawm to los yog kev huam yuaj, lawv yuav tsum tau muab tshem tawm nyob rau hauv lub sij hawm thiab tsim nyog yuav tsum tau ua raws li cov kev cai thaum muaj xwm ceev. Thaum siv cov khoom sib xyaw no, cov txheej txheem kev nyab xeeb yuav tsum tau ua.
