Taw qhia
Methyloxaloyl chloride yog ib qho organic compound. Cov hauv qab no yog kev qhia txog nws qhov xwm txheej, kev siv, kev npaj thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
Methyloxaloyl chloride yog cov kua tsis muaj xim nrog cov ntxhiab tsw. Nws yog ib tug muaj zog acidic tshuaj uas reacts nrog dej los tsim formic acid thiab oxalic acid. Methyl oxaloyl chloride muaj siab vapor siab thiab volatility, thiab tib lub sij hawm muaj zog corrosiveness.
Siv:
Methyl oxaloyl chloride yog ib qho tseem ceeb nruab nrab ntawm cov organic synthesis. Oxalyl methyl chloride tuaj yeem siv rau ntau yam kev sib xyaw ua ke ntawm cov organic, xws li cov tshuaj tiv thaiv acylation, cov tshuaj tiv thaiv esterification thiab carboxylic acid derivative synthesis.
Txoj kev:
Kev npaj ntawm methyl oxaloyl chloride feem ntau siv benzoic acid ua raw khoom, thiab oxaloyl chloroformimide yog tsim los ntawm kev ua ntawm thionyl chloride, thiab tom qab ntawd hydrolyzed kom tau methyl oxaloyl chloride.
Cov ntaub ntawv kev nyab xeeb:
Methyloxaloyl chloride ua rau khaus heev thiab corrosive, thiab tuaj yeem ua rau cov tshuaj kub hnyiab ntawm daim tawv nqaij thiab qhov muag. Kev sib cuag ncaj qha yuav tsum zam thaum siv thiab khaws cia. Cov hnab looj tes tiv thaiv tsim nyog, cov looj tsom iav thiab cov khoom tiv thaiv ua pa yuav tsum hnav thaum siv. Ua haujlwm hauv qhov chaw uas muaj cua zoo thiab tsis txhob nqus nws cov vapors. Thaum khaws cia, nws yuav tsum tau muab cais tawm ntawm cov oxidants, acids thiab alkalis kom tsis txhob muaj hluav taws kub thiab kev sib tsoo.
