Daim ntawv thov

Dimethyl Carbonate
1) Nws yog ib tug zoo meej methylating tus neeg saib xyuas, carbonylating tus neeg saib xyuas, methoxylating tus neeg saib xyuas thiab methylolating tus neeg saib xyuas nrog active tshuaj zog.Nws tuaj yeem siv los ua polypropylene carbonate.
2) Hauv kev siv tshuaj thiab tshuaj tua kab, DMC tuaj yeem siv los tsim ciprofloxacin thiab carbadox.Tsis tas li ntawd nws yog ib qho tseem ceeb raw khoom los tsim lithium roj teeb electrolyte.Vim tias nws cov khoom siv tshuaj lom neeg zoo thiab ib puag ncig, tsis ntev los no DMC tau ua cov kuab tshuaj zoo rau txheej, xim, number case thiab nplaum hloov cov benzene, xylene, ethyl acetate, butyl acetate, acetone, butanone, toluene.Nws yog ib qho zoo tagnrho hloov rau cov tshuaj lom xws li phosgene, dimethyl sulphate, thiab methyl chloraformate.
3) Dimethyl carbonate (DMC), yog ib yam tseem ceeb intermediates organic synthesis, molecular qauv muaj carbonyl, methyl thiab armour, xws li oxygen functional pab pawg neeg, muaj ntau yam tshuaj tiv thaiv kev ua tau zoo nyob rau hauv ntau lawm kev ruaj ntseg, yooj yim, siv tsawg muaj kuab paug, yooj yim thauj tag nrho cov yam ntxwv.Vim tias qhov qis dua toxicity dimethyl carbonate, yog cov khoom muaj peev xwm "ntsuab" tshuaj.
