Kev Siv
Dimethyl carbonate yog siv ua cov kuab tshuaj hauv cov organic synthesis thiab suav hais tias yog ib qho kev hloov pauv rau cov kuab tshuaj zoo li methyl ethyl ketone, tert-butyl acetate thiab parachlorobenzotrifluoride. Nws koom nrog ua ib qho nruab nrab hauv kev npaj ntawm diphenylcarbonate, uas yog siv ua cov khoom siv tseem ceeb rau kev tsim cov Bisphenol-A-polycarbonate. Nws kuj tseem siv ua tus neeg sawv cev 'ntsuab' methylating koom nrog hauv methylation ntawm aniline, phenols thiab carboxylic acids. Nws tuaj yeem siv ua cov roj ntxiv vim nws cov ntsiab lus oxygen siab. Nws kuj pom cov ntawv thov cuam tshuam nrog supercapacitors thiab lithium roj teeb.
Ib puag ncig zoo rau dimethyl sulfate, qv, thiab methyl halides hauv methylation reactions thiab rau phosgene, qv, hauv methylcarbonylation reactions.
Ntim thiab Xa Khoom
200KG / Nruas los yog raws li cov neeg siv khoom xav tau.
Yog cov khoom siv dav dav thiab tuaj yeem xa los ntawm dej hiav txwv thiab huab cua
Khaws cia thiab khaws cia
Lub neej txee: 24 lub hlis txij li hnub tsim khoom hauv cov ntim khoom tsis tau qhib khaws cia rau hauv qhov chaw txias thiab qhuav kom tsis txhob raug tshav ntuj ncaj qha, dej.
Lub tsev rau khoom muaj cua nkag, ziab kom qhuav kub tsawg, Sib cais ntawm cov tshuaj oxidants, cov kua qaub.
