Taw qhia
Tom ntej: Methyl Thioethyl S-acid Branyl Cov hauv qab no yog kev qhia txog cov khoom, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb ntawm methyl thioethyl thioS-acid furfur:
Zoo:
Methyl thioethyl S-fufrate yog cov kua tsis muaj xim nrog ib qho tshwj xeeb methyl sulfate saj. Nws yog soluble hauv cov kuab tshuaj organic xws li cawv, ketones, thiab ethers, tab sis insoluble hauv dej.
Siv:
Methyl thioethyl S-furfur yog dav siv nyob rau hauv cov organic synthesis. Nws tuaj yeem siv los ua ib qho reagent rau ntau yam organic synthesis cov tshuaj tiv thaiv, xws li carbonylation ntawm amines, esterification thiab acylation ntawm alcohols, thiab lwm yam. Methyl thioethyl S-furfur kuj tseem siv tau los ua cov tshuaj tiv thaiv thiab hnyav.
Txoj kev:
Kev npaj ntawm methyl thioethyl S-acid furfur yog feem ntau tau los ntawm cov tshuaj tiv thaiv ntawm carbon disulfide nrog methyl chloroacetate. Txoj kev npaj tshwj xeeb yog raws li hauv qab no: carbon disulfide maj mam poob rau hauv methyl chloroacetate hauv dej khov, thiab cov tshuaj tiv thaiv yog nplawm tib lub sijhawm. Tom qab cov tshuaj tiv thaiv tiav, cov tshuaj tiv thaiv yog ntxiv rau cov tshuaj saturated sodium chloride, thiab tom qab ntawd cov txheej txheem organic tau muab rho tawm thiab qhuav nrog anhydrous sodium chloride. Methyl thioethyl S-acid furfur yog tau los ntawm distillation.
Cov ntaub ntawv kev nyab xeeb:
Methyl thioethyl S-furfur yog cov kuab tshuaj organic uas muaj ntxhiab tsw thiab yuav tsum tau zam thaum siv. Thaum ua haujlwm, cov cuab yeej tiv thaiv tsim nyog xws li tsom iav thiab hnab looj tes yuav tsum hnav. Nws yuav tsum tau muab cia rau hauv qhov chaw txias, qhuav, zoo-ventilated, deb ntawm ignition thiab oxidizers, kom tsis txhob muaj hluav taws kub thiab tawg. Rau kev siv thiab khaws cia cov tshuaj, nws yog ib qho tseem ceeb kom ua raws li cov kev coj ua kom zoo.
