Dimethyl sulfoxide CAS 67-68-5
Dimethyl sulfide yog ib qho muaj zog uas tsis yog protonated polar compound, yog li nws tsis muaj acidity lossis alkalinity. Nyob rau hauv chav tsev kub, nws yog cov kua xim tsis muaj xim nrog hygroscopicity. Yuav luag odorless, nrog ib tug iab saj. Soluble hauv dej, ethanol, acetone, ether, benzene, thiab chloroform. Cov khoom no tsis muaj zog alkaline, tsis ruaj khov rau cov kua qaub, thiab ua cov ntsev thaum ntsib cov acids muaj zog. Nws decomposes ntawm qhov kub thiab txias thiab reacts hnyav nrog chlorine, emitting ib lub teeb xiav nplaim thaum hlawv nyob rau hauv cov huab cua.

Dimethyl sulfide yog siv los ua cov tshuaj analytical reagent thiab roj chromatography nyob ruaj khov theem, nrog rau cov kuab tshuaj rau UV spectroscopic tsom xam. Nws kuj yog siv los ua cov tshuaj tiv thaiv nruab nrab rau cov tshuaj tsw qab hydrocarbon extraction, resin thiab dye, ib qho hnyav rau acrylic polymerization, thiab kos duab lo lo ntxhuav. Dimethyl sulfide tuaj yeem siv los ua cov kuab tshuaj organic, tshuaj tiv thaiv nruab nrab, thiab nruab nrab hauv cov organic synthesis. Siv dav.
Feem ntau ntim rau hauv 25kg / nruas, thiab kuj tuaj yeem ua pob customized.
