Dimethyl sulfoxide CAS 67-68-5 yog dab tsi?

Dimethyl sulfide 67-68-5 yog ib qho tshuaj polar uas tsis muaj protonated heev, yog li ntawd nws tsis muaj acidity lossis alkalinity. Thaum sov chav, DMSO yog ib qho kua tsis muaj xim nrog hygroscopicity. Yuav luag tsis muaj ntxhiab, nrog rau qhov saj iab. Yaj hauv dej, ethanol, acetone, ether, benzene, thiab chloroform. Dimethyl sulfoxide DMSO yog alkaline tsis muaj zog, tsis ruaj khov rau cov kua qaub, thiab tsim cov ntsev thaum ntsib cov kua qaub muaj zog. Dimethyl sulfoxide DMSO decomposes ntawm qhov kub siab thiab reacts hnyav nrog chlorine, emitting lub teeb xiav nplaim thaum hlawv hauv huab cua.
