Txheej txheem cej luam:
Dimethyl sulfoxide (luv luv DMSO) yog ib qho organic compound uas muaj sulfur; cov mis molecule: (CH3) 2SO; Nws ua rau pom tias tsis muaj xim, tsis muaj ntxhiab, hygroscopic thiab yooj yim hlawv thaum kub hauv chav. Nws muaj ob qho tib si polarity siab thiab kub kub. Nws kuj muaj cov yam ntxwv aprotic thiab dej-miscible. Nws muaj tshuaj lom tsawg, thermal stability zoo, thiab tsis sib xyaw nrog paraffin. Nws yaj tau hauv dej, ethanol, propanol, ether, benzene thiab chloroform thiab ntau lwm yam organic substance thiab hu ua "universal solvent." Nws yog ib qho organic solvent uas muaj peev xwm yaj tau zoo tshaj plaws. Nws tuaj yeem yaj feem ntau cov organic compounds xws li carbohydrates, polymers, peptides, nrog rau ntau cov ntsev thiab roj inorganic. Nws tuaj yeem yaj qee qhov solute uas qhov hnyav sib npaug li 50-60% ntawm nws tus kheej (lwm cov solvents feem ntau tsuas yog yaj 10-20%), yog li nws tseem ceeb heev rau kev tswj cov qauv thiab kev tshuaj xyuas cov tshuaj sai. Nyob rau hauv qee qhov xwm txheej, kev sib cuag ntawm dimethyl sulfoxide thiab chloride tuaj yeem ua rau muaj kev tawg.

Kev Siv
1. Nws siv tau rau kev rho tawm ntawm arene, kuj yog cov tshuaj tiv thaiv siv rau cov resins thiab dyes, thiab siv rau acrylic polymerization thiab spinning solvent.
2. Nws siv tau ua cov organic solvent, reaction medium thiab cov intermediates ntawm organic synthesis. Nws muaj ntau yam siv tau. Cov khoom no muaj peev xwm rho tawm tau zoo heev, thiab siv tau ua cov polymerization thiab condensation solvent ntawm acrylic resin thiab polysulfone resin, ua cov polymerization thiab spinning solvent ntawm polyacrylonitrile thiab cellulose acetate, ua cov extraction solvent rau kev sib cais alkanes thiab arenes, thiab ua cov reaction medium rau arenes, butadiene extraction, acrylic fiber, plastic solvents, organic thiab synthetic dyes, thiab pharmaceuticals industries. Hauv kev kho mob, dimethyl sulfoxide muaj cov nyhuv anti-inflammatory thiab analgesic nrog lub peev xwm nkag mus rau hauv daim tawv nqaij, thiab yog li ntawd muaj peev xwm yaj qee yam tshuaj thiab txhawb lawv nkag mus rau hauv tib neeg lub cev kom ua tiav cov hom phiaj kho mob. Kev siv cov khoom no ntawm dimethyl sulfoxide tuaj yeem ua rau nws siv tau ua cov tshuaj tua kab. Ntxiv me ntsis ntawm dimethyl sulfoxide rau hauv qee cov tshuaj tua kab tuaj yeem pab txhawb kev nkag mus rau hauv cov nroj tsuag kom txhim kho qhov ua tau zoo. dimethyl sulfoxide kuj tseem siv tau ua cov dye solvent, dye removal agent, thiab dye carrier rau cov synthetic fibers. Nws kuj tseem siv tau ua tus nqus dej ntawm kev siv cov acetylene thiab sulfur dioxide thiab tseem yog cov hloov kho ntawm cov fiber hluavtaws, tus neeg sawv cev antifreeze thiab lub capacitor dielectric, roj nres, thiab extractant ntawm cov hlau tsis tshua muaj.
3. Nws siv tau ua cov tshuaj solvents thiab cov neeg sawv cev kho ntawm cov roj chromatography nrog rau cov tshuaj rau kev tshuaj xyuas UV spectra.
