Khoom Description
Dimethyl sulfoxide (DMSO) yog sulfur-muaj cov organic compound, cov mis molecular yog C2H6OS, nyob rau hauv chav tsev kub yog cov xim tsis muaj ntxhiab tsw pob tshab kua, yog hygrometric flammable kua. Nrog siab polarity, siab kub taw tes, zoo thermal stability, aprotic, thiab dej miscible yam ntxwv, yuav yaj nyob rau hauv ethanol, propanol, benzene thiab chloroform thiab lwm yam organic teeb meem, hu ua "universal hnyav". Nyob rau hauv lub xub ntiag ntawm acid, cua sov yuav tsim ib tug me me ntawm methyl mercaptan, formaldehyde, dimethyl sulfur, mesylate thiab lwm yam compounds. Decomposition phenomenon ntawm qhov kub thiab txias, chlorine tuaj yeem tshwm sim ua phem tawm tsam, kub hnyiab hauv huab cua tawm lub teeb xiav nplaim. Nws tuaj yeem siv ua cov kuab tshuaj organic, cov tshuaj tiv thaiv nruab nrab thiab nruab nrab ntawm cov organic synthesis. Nws kuj tseem siv tau los ua cov kuab tshuaj dye, dye remover, dye carrier thiab absorbent rau recovering acetylene thiab sulfur dioxide ntawm hluavtaws fibers.

tuaj yeem tov nrog dej hauv txhua qhov kev faib ua feem, ntxiv rau roj av ether, tuaj yeem yaj cov kuab tshuaj organic. Ntawm 20 ° C, nws tuaj yeem nqus tau 30% hydrogen chloride (qhov hnyav), 30% nitrogen dioxide (qhov hnyav), 65% sulfur dioxide (qhov hnyav), thiab yog insoluble hauv aliphatic hydrocarbons tshwj tsis yog acetylene. Nws muaj peev xwm yaj ntau cov tebchaw. Soluble hauv dej, ethylene glycol, acetone, benzene, hydrocarbon chloride, ethylene glycol ester, thiab lwm yam. |
daim ntawv thov
1.Dimethyl sulfoxide yog dav siv los ua cov kuab tshuaj thiab cov tshuaj tiv thaiv reagent, tshwj xeeb tshaj yog ua cov kuab tshuaj thiab nqus cov kuab tshuaj hauv acrylonitrile polymerization, ua kuab tshuaj rau polyurethane synthesis thiab kos duab, ua kuab tshuaj rau polyamide, polyimide thiab polysulfone resin synthesis, thiab ib qho hnyav rau aromatics, butadiene extraction thiab synthesis ntawm chlorofluoroaniline.
2.Dimethyl sulfoxide yog siv los ua ib qho hnyav rau acetylene, aromatics, sulfur dioxide thiab lwm yam gases thiab ua ib qho hnyav hnyav rau acrylic fibers. Nws yog ib qho tseem ceeb heev aprotic polar solvent soluble hauv dej thiab organic solvents. Nws yog permeable heev rau daim tawv nqaij thiab pab cov tshuaj nkag mus rau hauv tib neeg lub cev. Nws kuj tseem siv tau los ua ib qho ntxiv rau tshuaj tua kab. Nws kuj yog ib qho tseem ceeb ntawm cov tshuaj chemical.
3.Transition hlau halides xws li chromium chloride, manganese chloride thiab potassium chloride, sodium chloride thiab lwm yam halides muaj qee yam solubility hauv DMSO, yog li lawv tuaj yeem siv rau hauv cov organic electrochemistry.
4.Dimethyl sulfoxide kuj yog ib qho kev tiv thaiv osmotic, uas tuaj yeem txo qhov khov ntawm cov hlwb, txo qhov tsim ntawm cov dej khov, txo qhov kev puas tsuaj ntawm cov dawb radicals rau cov hlwb, thiab hloov cov permeability ntawm biofilms rau electrolytes, tshuaj, tshuaj lom thiab metabolites. .
