"Bimolecular dehydration" yog ib txoj hauv kev npaj diethyl ether los ntawm lub cev qhuav dej ntawm cov concentrated sulfuric acid ntawm ethanol… Yog li txoj kev no tsuas yog ua haujlwm nrog symmetrical ethers, Methyl Ethyl ether yog Npaj zoo dua los ntawm Sodium ethoxide thiab methanol lossis Sodium methoxide thiab ethanol.
Koj puas tuaj yeem piav qhia vim li cas vim li cas molecular lub cev qhuav dej tsis tsim nyog rau kev npaj ntawm ethyl methyl ether?
Lub cev qhuav dej ntawm cov dej cawv theem nrab thiab theem nrab kom tau txais cov ethers sib xws tsis ua tiav vim alkenes tau tsim tau yooj yim hauv cov tshuaj tiv thaiv no. Cov tshuaj tiv thaiv no tsis tuaj yeem ua haujlwm los npaj cov ethers tsis sib xws. Nws yog vim sib xyaw ntawm cov khoom yuav tau txais
Vim li cas peb thiaj npaj ethyl methyl ether?
Methoxyethane tseem hu ua ethyl methyl ether. Nws yog ntshiab xim tsis muaj roj nrog ib qho tsw ntawm tshuaj. Nws qhov kub ntawm qhov kub yog qis heev (7.6 oC). … Txij li thaum nws yog qhov hluav taws kub heevyog li ntawm qhov raug tshav kub lossis hluav taws ntev ntev, cov thawv ntim uas muaj cov Methoxyethane tuaj yeem tawg ua rau hnyav.
Yuav ua li cas yog condensed qauv qauv rau ethyl methyl ether?
Ethyl methyl ether | C3H8O - PubChem.
CH3OCH3 hu li cas?
Dimethyl ether (DME, tseem hu ua methoxymethane)yog cov organic compound nrog cov mis CH3OCH3, simplified rau C2H6O.
