Kufotokozera Kwachidule:
Dzina la Mankhwala: Dimethyl carbonate
CAS: 616-38-6
Mtundu: ZA-Y
MF:C3H6O3
MW:90.08
KAYAMBIDWE:
Kufotokozera:
Dimethyl carbonate imawoneka ngati madzi oyera, opanda mtundu komanso onunkhira bwino. Ndi yokhuthala kuposa madzi ndipo imasungunuka pang'ono m'madzi. Nthunzi ndi yolemera kuposa mpweya. Imagwiritsidwa ntchito popanga mankhwala ena komanso ngati chosungunulira chapadera.

Kagwiritsidwe Ntchito
Dimethyl carbonate imagwiritsidwa ntchito ngati chosungunulira mu kapangidwe ka organic ndipo imawonedwa ngati m'malo mwa chosungunulira monga methyl ethyl ketone, tert-butyl acetate ndi parachlorobenzotrifluoride. Imagwira ntchito ngati gawo lapakati pakukonzekera diphenylcarbonate, yomwe imagwiritsidwanso ntchito ngati zinthu zofunika kwambiri popanga Bisphenol-A-polycarbonate. Imagwiritsidwanso ntchito ngati 'wobiriwira' wothandizira methylation womwe umakhudzidwa ndi methylation ya aniline, phenols ndi carboxylic acids. Ingagwiritsidwe ntchito ngati chowonjezera cha mafuta chifukwa cha kuchuluka kwa okosijeni. Imapezekanso ntchito zokhudzana ndi ma supercapacitors ndi mabatire a lithiamu.
Cholowa m'malo mwa dimethyl sulfate, qv, ndi methyl halides mu methylation reactions ndi phosgene, qv, mu methylcarbonylation reactions.
Kulongedza ndi Kutumiza
200KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
