Khoom Description
Dichloromethane (DCM), tseem hu ua Methylene Chloride, nrog cov mis molecular CH₂Cl₂, yog cov kua tsis muaj xim tsis muaj pob tshab uas muaj lub zog hnyav thiab tsis muaj zog. Hauv qab no yog cov khoom tseem ceeb ntawm dichloromethane:
- Chemical Properties: DCM yog ib tug polar molecule soluble nyob rau hauv ntau cov organic solvents thiab dej. Nws ua raws li tus neeg sawv cev muaj zog thiab tsim cov ntsev sib xyaw nrog cov hlau.
- Lub cev muaj zog: Ntawm tus qauv siab, DCM muaj nyob rau hauv cov xim tsis muaj xim, pob tshab kua nrog cov ntxhiab tsw. Nws qhov ceev yog 1.33 g / cm³, kub taw tes yog 39.8 degree, thiab txheeb ze molecular loj yog 84.93.
