Taw qhia
Diethyl methyl phosphate (tseem hu ua diethyl methyl phosphophosphate, abbreviated li MOP (Methyl-ortho-phosphoricdiethylester)) yog ib qho organophosphate compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev tsim khoom thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
Cov tsos mob: tsis muaj xim lossis yellowish kua;
Solubility: soluble hauv cov kuab tshuaj organic xws li dej, cawv thiab ether;
Siv:
Diethyl methyl phosphate feem ntau yog siv los ua catalyst thiab hnyav hauv cov organic synthesis cov tshuaj tiv thaiv;
Nws ua raws li kev hloov pauv hauv qee qhov esterification, sulfonation, thiab etherification cov tshuaj tiv thaiv;
Diethyl methyl phosphate kuj tseem siv tau rau hauv kev npaj ntawm qee cov tshuaj tiv thaiv cov nroj tsuag.
Txoj kev:
Kev npaj ntawm diethyl methyl phosphate tuaj yeem tau txais los ntawm cov tshuaj tiv thaiv ntawm diethanol thiab trimethyl phosphate. Txoj kev npaj tshwj xeeb yog raws li hauv qab no:
(CH3O) 3PO + 2C2H5OH → (CH3O) 2POOC2H5 + CH3OH
Cov ntaub ntawv kev nyab xeeb:
Diethyl methyl phosphate yuav tsum raug zam los ntawm kev sib cuag nrog cov oxidants muaj zog thiab muaj zog acids kom tsis txhob muaj kev phom sij txaus ntshai;
Thaum siv los yog khaws cia diethyl methyl phosphate, yuav tsum tau saib xyuas kom tsis txhob muaj cua sov thiab qhib nplaim taws kom ntseeg tau tias muaj qhov cua zoo.
