Daim ntawv thov
Dimethyl sulfoxide yog dav siv los ua hnyav, cov tshuaj tiv thaiv reagent thiab cov organic synthesis nruab nrab, tshwj xeeb tshaj yog ua cov kuab tshuaj thiab cov ntaub ntawv nqus cov kuab tshuaj hauv acrylonitrile polymerization cov tshuaj tiv thaiv, ua hnyav rau polyurethane synthesis thiab filament drawing, hnyav rau polyamide, polyimide thiab polysulfone resin, thiab Cov kuab tshuaj rau aromatic hydrocarbon thiab butadiene extraction thiab hnyav rau synthesizing chlorofluoroaniline.Tsis tas li ntawd, dimethyl sulfoxide yog siv ncaj qha los ua cov khoom siv raw thiab cov nqa ntawm qee cov tshuaj hauv kev lag luam kws tshuaj.Dimethyl sulfoxide (DMSO) nws tus kheej muaj cov tshuaj tiv thaiv kab mob, tshuaj tua kab mob, diuretic thiab sedative teebmeem, thiab tseem hu ua "panacea", uas feem ntau ntxiv rau cov tshuaj raws li cov khoom siv ntawm cov tshuaj analgesic.
Dimethyl sulfoxide (DMSO) yog cov tshuaj sulfur-muaj cov organic sib xyaw nrog cov mis molecular C2H6OS, cov kua dej tsis muaj xim thiab tsis muaj ntxhiab tsw ntawm chav tsev kub, thiab hygroscopic flammable kua.Nws muaj cov yam ntxwv ntawm siab polarity, siab kub taw tes, zoo thermal stability, non-protonic, miscible nrog dej, soluble nyob rau hauv feem ntau cov organic tshuaj xws li ethanol, propanol, benzene thiab chloroform, thiab lwm yam. Nws yog hu ua "universal hnyav".Thaum rhuab nyob rau hauv lub xub ntiag ntawm acid, me me ntawm methyl mercaptan, formaldehyde, dimethyl sulfide, methanesulfonic acid thiab lwm cov tebchaw yuav raug tsim.Nws decomposes ntawm qhov kub thiab txias, reacts hnyav nrog chlorine, thiab hlawv nyob rau hauv cov huab cua nrog lub teeb xiav nplaim.Nws tuaj yeem siv ua cov kuab tshuaj organic, cov tshuaj tiv thaiv nruab nrab thiab cov organic synthesis nruab nrab.Nws kuj tseem siv tau los ua dyeing hnyav ntawm hluavtaws fiber, dyeing tus neeg sawv cev, dyeing cab kuj thiab absorbent ntawm recovering acetylene thiab sulfur dioxide.
Lub cev muaj zog.
Cov kua dej tsis muaj xim.Combustible, yuav luag odorless, nrog iab saj, hygroscopic.Tsuas yog cov roj av ether, nws tuaj yeem yaj cov kuab tshuaj organic.Nws tuaj yeem soluble hauv dej, ethanol, acetone, acetaldehyde, pyridine, ethyl acetate, dibutyl benzodicarboxylate, dioxane thiab cov tshuaj tsw qab, tab sis insoluble hauv aliphatic hydrocarbon tebchaw uas tsis yog acetylene.Nws muaj zog hygroscopicity thiab tuaj yeem nqus dej sib npaug li 70% ntawm nws tus kheej qhov hnyav los ntawm huab cua ntawm 20 ℃ thaum cov txheeb ze av noo yog 60%.Cov khoom yog ib qho tsis muaj zog oxidizer, thiab dimethyl sulfoxide tsis muaj dej tsis corrosive rau hlau.Thaum muaj dej, nws yog corrosive rau hlau;tooj liab thiab lwm yam hlau, tab sis tsis yog rau txhuas.ruaj khov rau hauv paus.Cua sov nyob rau hauv lub xub ntiag ntawm acid yuav tsim ib tug me me ntawm methyl mercaptan, formaldehyde, dimethyl sulfide;methanesulfonic acid thiab lwm yam tshuaj.Decomposition ntawm qhov kub thiab txias, tuaj yeem cuam tshuam nrog cov tshuaj chlorine, hlawv hauv huab cua nrog lub teeb xiav nplaim.
