Umkhiqizi Intengo Enhle I-Dimethyl Sulfoxide (DMSO) I-CAS 67-68-5
incazelo
Ingenye yezincibilikisi eziphilayo ezisetshenziswa kakhulu ezinokuncibilika okuqine kakhulu.Ingancibilikisa izinto eziningi eziphilayo, okuhlanganisa ama-carbohydrates, ama-polymers, ama-peptides, nosawoti omningi namagesi wezinto ezingaphili.Ingancibilikisa i-50-60% yesisindo sayo se-solute (ezinye izincibilikisi ezivamile zingancibilikisa kuphela i-10-20%), ngakho-ke kubaluleke kakhulu ekuphathweni kwesampula kanye nokuhlolwa kwezidakamizwa ngesivinini esikhulu.Ngaphansi kwezimo ezithile, ukusabela kokuqhuma kungenzeka lapho i-Dimethyl sulfoxide ihlangana ne-asidi chloride.I-Dimethyl sulfoxide isetshenziswa kabanzi njenge-solvent kanye ne-reagent, ikakhulukazi njengokucubungula i-solvent nokuphotha i-solvent ku-acrylonitrile polymerization, njenge-polyurethane synthesis kanye ne-solvent yokuphotha, njenge-polyamide, i-polyimide ne-polysulfone resin synthesis synthes Solvents, i-Chemicalbook nama-hydrocarbons anephunga elimnandi, i-butadiene extraction solvents kanye ne-solvents ukuhlanganiswa kwe-chlorofluoroaniline, njll. Ngaphezu kwalokho, embonini yezemithi, i-dimethyl sulfoxide iphinde isetshenziswe ngokuqondile njengempahla eluhlaza kanye nomthwali wezinye izidakamizwa.I-Dimethyl sulfoxide ngokwayo ine-anti-inflammatory and relieving, diuretic, sedative kanye neminye imiphumela, eyaziwa nangokuthi "i-panacea", futhi ivame ukungezwa ezidakamizweni njengengxenye esebenzayo yezidakamizwa ezidambisa izinhlungu.Inesici esikhethekile sokungena esikhunjeni kalula, okuholela ekunambithekeni okufana ne-oyster kumsebenzisi.I-sodium cyanide ku-dimethyl sulfoxide ingabangela ubuthi be-cyanide ngokuthinta isikhumba.Futhi i-dimethyl sulfoxide ngokwayo ayinabo ubuthi obuncane.I-Dimethyl sulfoxide isetshenziswa njenge-extractant yizinkampani eziningi zamakhemikhali nezemithi.Kodwa-ke, ngenxa yezinga eliphezulu lokubilisa le-DMSO, izinga lokushisa lokusebenza liphezulu kakhulu, okuholela ekuphekeni kwezinto, okuthinta ukubuyiswa kwe-dimethyl sulfoxide nokuhlanza imishini.Khulisa ukusetshenziswa kwamandla.Ngakho-ke, ukutholwa kwe-DMSO sekuphenduke ibhodlela ekusetshenzisweni kwayo kabanzi njenge-extractant.I-Dimethyl sulfoxide iyi-solvent evamile ye-aprotic organic esetshenziselwa ukuncibilikisa inhlanganisela ye-polar ne-nonpolar.Ifomu elihoxisiwe, i-DMSO-d6 (D479382), elisetshenziselwa ikakhulukazi izifundo ze-NMR, libonakala kalula nge-spectrum yalo ye-NMR ngenxa yekhono layo lokuhlakaza iningi labahlaziyi.

Izicelo ze-DMSO
1. I-DMSO isetshenziselwa ukukhipha i-hydrocarbon enephunga elimnandi, indawo yokusabela ye-resin nodayi, i-acrylic fiber polymerization, ne-solvent yokuphotha, njll.
2. I-DMSO ingasetshenziswa njenge-solvent ephilayo, i-reaction medium kanye ne-organic synthesis intermediate.Iguquguquka kakhulu.Lo mkhiqizo unamandla okukhetha aphezulu, asetshenziswa njenge-polymerization kanye ne-condensation solvent ye-acrylic resin ne-polysulfone resin, i-polymerization kanye ne-solvent yokuphotha ye-polyacrylonitrile ne-acetate fiber, i-solvent yokukhipha i-alkane kanye nokuhlukaniswa kwe-hydrocarbon enamakha.I-aromatic hydrocarbon, i-butadiene extraction, i-acrylic fibre spinning, i-solvent yepulasitiki kanye ne-reaction medium yodayi bokwenziwa be-organic, imithi kanye nezinye izimboni.Ngokwemithi, i-dimethyl sulfoxide inemiphumela elwa nokuvuvukala kanye ne-analgesic, futhi inamandla anamandla angena esikhumbeni, ngakho-ke ingahlakaza izidakamizwa ezithile ku-Chemicalbook, ukuze izidakamizwa ezinjalo zingene emzimbeni womuntu ukuze zifeze injongo yokwelashwa.Kusetshenziswa lesi sithako se-dimethyl sulfoxide, singasetshenziswa futhi njengesithasiselo sezibulala-zinambuzane.Inani elincane le-dimethyl sulfoxide liyengezwa kwezinye izibulala-zinambuzane ukusiza isibulala-zinambuzane singene esitshalweni ukuze sithuthukise ukusebenza kahle.I-Dimethyl sulfoxide ingasetshenziswa futhi njenge-solvent yokudaya, i-de-staining ejenti, isithwali sokudaya semicu yokwenziwa, imunca ukubuyisa i-acetylene ne-sulphur dioxide, i-synthetic fiber modifier, i-antifreeze, i-capacitor medium, uwoyela wamabhuleki, ukukhishwa kwe-ejenti yezinsimbi ezingavamile, njll.
I-3.DMSO ingasetshenziswa njenge-reagent yokuhlaziya kanye noketshezi olungashintshi lwe-chromatography yegesi, futhi isetshenziswe njengesixazululi ekuhlaziyweni kwe-ultraviolet spectrum.
4.DMSO organic solvent, reaction medium and organic synthesis intermediate.Iguquguquka kakhulu.Ngekhono eliphezulu lokukhetha elikhethiwe, isetshenziswa njenge-polymerization kanye ne-condensation solvent ye-acrylic resin ne-polysulfone resin, i-polymerization kanye ne-solvent yokuphotha ye-polyacrylonitrile ne-acetate fiber Chemicalbook, i-solvent yokukhipha i-alkane kanye nokuhlukaniswa kwe-hydrocarbon enamakha, okusetshenziselwa i-hydrocarbon ephunga elimnandi, i-Butadiene. isizinda, i-acrylic fibre spinning, i-solvent yepulasitiki kanye nodayi be-organic synthetic, imithi kanye nezinye izimboni zokusabela.Ngokwemithi, inemiphumela elwa nokuvuvukala kanye ne-analgesic, futhi inokungena okuqinile esikhumbeni.
