piav qhia
Nws yog ib qho ntawm cov organic solvents uas siv ntau tshaj plaws nrog qhov solubility zoo tshaj plaws. Nws tuaj yeem yaj feem ntau cov organic matter, suav nrog carbohydrates, polymers, peptides, thiab ntau cov inorganic ntsev thiab roj. Nws tuaj yeem yaj 50-60% ntawm nws qhov hnyav ntawm solute (lwm cov solvents dav dav tsuas yog yaj 10-20%), yog li nws tseem ceeb heev rau kev tswj cov qauv thiab kev tshuaj ntsuam ceev ceev. Hauv qee qhov xwm txheej, kev tawm tsam tawg tuaj yeem tshwm sim thaum Dimethyl sulfoxide los rau hauv kev sib cuag nrog cov kua qaub chloride. Dimethyl sulfoxide yog siv dav ua cov kuab tshuaj thiab reagent, tshwj xeeb tshaj yog ua cov kuab tshuaj ua tiav thiab cov kuab tshuaj spinning hauv acrylonitrile polymerization, ua polyurethane synthesis thiab cov kuab tshuaj spinning, ua polyamide, polyimide thiab polysulfone resin synthesis Solvents, Chemicalbook thiab aromatic hydrocarbons, butadiene extraction solvents thiab cov kuab tshuaj rau kev tsim cov chlorofluoroaniline, thiab lwm yam. Tsis tas li ntawd, hauv kev lag luam tshuaj, dimethyl sulfoxide kuj tseem siv ncaj qha ua cov khoom siv raw thiab tus neeg nqa khoom ntawm qee cov tshuaj. Dimethyl sulfoxide nws tus kheej muaj cov tshuaj tiv thaiv kev o thiab kev mob, diuretic, sedative thiab lwm yam teebmeem, tseem hu ua "panacea", thiab feem ntau ntxiv rau cov tshuaj ua ib feem ntawm cov tshuaj mob. Muaj cov khoom tshwj xeeb ntawm kev nkag mus rau hauv daim tawv nqaij yooj yim heev, ua rau tus neeg siv saj zoo li oyster. Sodium cyanide hauv dimethyl sulfoxide tuaj yeem ua rau cyanide lom los ntawm kev sib cuag ntawm daim tawv nqaij. Thiab dimethyl sulfoxide nws tus kheej tsis muaj tshuaj lom. Dimethyl sulfoxide yog siv los ua cov tshuaj rho tawm los ntawm feem ntau ntawm cov tuam txhab tshuaj lom neeg thiab tshuaj. Txawm li cas los xij, vim yog qhov kub siab ntawm DMSO, qhov kub ua haujlwm siab dhau, uas ua rau cov khoom siv coking, uas cuam tshuam rau kev rov qab los ntawm dimethyl sulfoxide thiab kev ntxuav khoom siv. Ua kom siv hluav taws xob ntau dua. Yog li ntawd, kev rov qab los ntawm DMSO tau dhau los ua qhov tsis zoo rau nws txoj kev siv dav dav ua cov tshuaj rho tawm. Dimethyl sulfoxide yog cov tshuaj aprotic organic uas siv los yaj cov tshuaj polar thiab nonpolar. Daim ntawv deuterated, DMSO-d6 (D479382), siv feem ntau rau kev tshawb fawb NMR, yooj yim paub los ntawm nws cov NMR spectrum vim nws muaj peev xwm yaj feem ntau cov analytes.
