Tuam Tshoj Tus Nqi Zoo Dimethyl Sulfoxide (DMSO) CAS 67-68-5
piav qhia
Nws yog ib qho ntawm feem ntau siv cov kuab tshuaj organic nrog lub zog solubility.Nws tuaj yeem yaj feem ntau cov organic teeb meem, suav nrog carbohydrates, polymers, peptides, thiab ntau inorganic ntsev thiab roj.Nws tuaj yeem yaj 50-60% ntawm nws tus kheej qhov hnyav ntawm cov kuab tshuaj (lwm cov kuab tshuaj muaj peev xwm tsuas yog yaj 10-20%), yog li nws tseem ceeb heev hauv kev tswj cov qauv thiab kev tshuaj ntsuam xyuas tshuaj ceev.Hauv qee qhov xwm txheej, cov tshuaj tiv thaiv tawg tuaj yeem tshwm sim thaum Dimethyl sulfoxide los rau hauv cov kua qaub chloride.Dimethyl sulfoxide yog dav siv los ua hnyav thiab reagent, tshwj xeeb tshaj yog ua kuab tshuaj thiab spinning hnyav nyob rau hauv acrylonitrile polymerization, raws li polyurethane synthesis thiab spinning hnyav, raws li polyamide, polyimide thiab polysulfone resin synthesis Solvents, Tshuaj thiab muaj ntxhiab hydrocarbons, butadiene extraction cov kuab tshuaj thiab cov kuab tshuaj. synthesis ntawm chlorofluoroaniline, thiab lwm yam. Tsis tas li ntawd, hauv kev lag luam kws tshuaj, dimethyl sulfoxide tseem siv ncaj qha los ua cov khoom siv raw thiab cov khoom nqa ntawm qee cov tshuaj.Dimethyl sulfoxide nws tus kheej muaj cov tshuaj tiv thaiv kab mob thiab tshuaj tua kab mob, diuretic, sedative thiab lwm yam teebmeem, tseem hu ua "panacea", thiab feem ntau ntxiv rau cov tshuaj ua ib feem ntawm cov tshuaj kho mob.Muaj cov cuab yeej tshwj xeeb ntawm permeating ntawm daim tawv nqaij yooj yim heev, uas ua rau muaj qhov zoo li oyster saj rau tus neeg siv.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 extractant los ntawm feem ntau ntawm cov tuam txhab tshuaj thiab tshuaj.Txawm li cas los xij, vim yog qhov kub siab ntawm DMSO, kev ua haujlwm kub yog siab dhau, uas ua rau coking ntawm cov ntaub ntawv, uas cuam tshuam rau kev rov qab los ntawm dimethyl sulfoxide thiab cov khoom siv tu.Ua kom muaj zog noj.Yog li ntawd, kev rov qab los ntawm DMSO tau dhau los ua lub hauv paus rau nws txoj kev siv dav ntxiv los ua cov khoom siv ntxiv.Dimethyl sulfoxide yog ib hom aprotic organic hnyav siv los yaj cov polar thiab nonpolar tebchaw.Daim ntawv deuterated, DMSO-d6 (D479382), siv feem ntau rau NMR cov kev tshawb fawb, tau yooj yim txheeb xyuas los ntawm nws cov NMR spectrum vim nws muaj peev xwm ua kom yaj feem ntau cov analytes.

Daim ntawv thov ntawm DMSO
1. DMSO yog siv rau aromatic hydrocarbon extraction, tshuaj tiv thaiv nruab nrab rau resin thiab dye, acrylic fiber polymerization, thiab hnyav rau spinning, thiab lwm yam.
2. DMSO tuaj yeem siv ua cov kuab tshuaj organic, cov tshuaj tiv thaiv nruab nrab thiab cov organic synthesis nruab nrab.Ntau yam heev.Cov khoom no muaj peev xwm xaiv tau siab, siv los ua cov polymerization thiab condensation hnyav ntawm acrylic resin thiab polysulfone resin, lub polymerization thiab spinning hnyav ntawm polyacrylonitrile thiab acetate fiber, extraction hnyav ntawm alkane thiab aromatic hydrocarbon sib cais.Aromatic hydrocarbon, butadiene extraction, acrylic fiber spinning, yas hnyav thiab cov tshuaj tiv thaiv nruab nrab rau cov organic hluavtaws dyes, kws tshuaj thiab lwm yam lag luam.Nyob rau hauv cov nqe lus ntawm cov tshuaj, dimethyl sulfoxide muaj anti-inflammatory thiab analgesic teebmeem, thiab muaj zog nkag mus rau daim tawv nqaij, yog li nws muaj peev xwm yaj tej yam tshuaj nyob rau hauv Chemicalbook, kom cov tshuaj no nkag mus rau hauv tib neeg lub cev kom ua tiav lub hom phiaj ntawm kev kho mob.Siv cov khoom nqa khoom no ntawm dimethyl sulfoxide, nws kuj tuaj yeem siv los ua cov tshuaj tua kab.Ib qho me me ntawm dimethyl sulfoxide ntxiv rau qee cov tshuaj tua kab los pab cov tshuaj tua kab nkag mus rau hauv cov nroj tsuag kom txhim kho kev ua tau zoo.Dimethyl sulfoxide kuj tseem siv tau los ua dyeing hnyav, de-staining tus neeg saib xyuas, dyeing carrier rau hluavtaws fibers, absorbent rau recovering acetylene thiab sulfur dioxide, hluavtaws fiber ntau modifier, antifreeze, capacitor nruab nrab, nres roj, extraction ntawm tsawg hlau tus neeg saib xyuas, thiab lwm yam.
3.DMSO tuaj yeem siv los ua cov tshuaj analytical reagent thiab tsau kua rau cov roj chromatography, thiab tseem siv los ua cov kuab tshuaj hauv ultraviolet spectrum tsom xam.
4.DMSO organic hnyav, tshuaj tiv thaiv nruab nrab thiab organic synthesis intermediate.Ntau yam heev.Nrog rau kev xaiv muaj peev xwm extraction siab, nws yog siv los ua cov polymerization thiab condensation hnyav ntawm acrylic resin thiab polysulfone resin, lub polymerization thiab spinning hnyav ntawm polyacrylonitrile thiab acetate fiber Chemicalbook, lub extraction hnyav ntawm alkane thiab aromatic hydrocarbon sib cais, siv rau aromatic hydrocarbon, Butadiene extraction, acrylic fiber spinning, yas hnyav thiab organic hluavtaws dyes, tshuaj thiab lwm yam kev lag luam cov tshuaj tiv thaiv nruab nrab.Nyob rau hauv cov nqe lus ntawm cov tshuaj, nws muaj anti-inflammatory thiab analgesic teebmeem, thiab muaj zog nkag mus rau hauv daim tawv nqaij.
