ISAKHIWO:
Ukubuka konke:
I-Dimethyl sulfoxide (i-DMSO efingqiwe) iyinhlanganisela yezinto eziphilayo equkethe i-sulfur; ifomula ye-molecule: (CH3) 2SO; Ibonakala njengoketshezi olucacile olungenambala, olungenaphunga, oluyi-hygroscopic futhi oluvuthayo ekushiseni kwegumbi. Inendawo ephezulu kanye nendawo yokubila ephezulu. Iphinde ibe nezici ezi-aprotic nezixubene namanzi. Inobuthi obuphansi, ukuqina okuhle kokushisa, futhi ayixubene ne-paraffin. Iyancibilika emanzini, i-ethanol, i-propanol, i-ether, i-benzene kanye ne-chloroform kanye nezinye izinhlobo eziningi zezinto eziphilayo futhi ibizwa ngokuthi "i-solvent yendawo yonke." Iyi-solvent evamile yezinto eziphilayo enekhono elinamandla kakhulu lokuncibilika. Ingancibilikisa iningi lamakhemikhali ezinto eziphilayo kufaka phakathi ama-carbohydrate, ama-polymer, ama-peptide, kanye nosawoti namagesi amaningi angaphili. Ingancibilikisa inani elithile le-solute elinesisindo esilingana no-50-60% walo (ezinye izincibilikisi ezivamile zivame ukuncibilikisa u-10-20%) kuphela, ngakho-ke ibaluleke kakhulu ekuphathweni kwesampula kanye nokuhlolwa kwezidakamizwa okusheshayo. Ngaphansi kwezimo ezithile, ukuthintana phakathi kwe-dimethyl sulfoxide ne-chloride kungaholela ngisho nasekuqhumeni kwe-explosive.

Ukusetshenziswa
1. Ingasetshenziswa ekukhipheni i-arene, futhi njengendlela yokusabela esetshenziselwa ama-resin namadayi, futhi isetshenziswe ku-polymerization ye-acrylic kanye ne-spinning solvent.
2. Ingasetshenziswa njenge-organic solvent, i-reaction medium kanye ne-intermediates yokwenziwa kwezinto eziphilayo. Iguquguqukayo kakhulu. Lo mkhiqizo unamandla okukhipha amakhemikhali akhethekile kakhulu, futhi ungasetshenziswa njenge-polymerization kanye ne-condensation solvent ye-acrylic resin kanye ne-polysulfone resin, njenge-polymerization kanye ne-spinning solvent ye-polyacrylonitrile kanye ne-cellulose acetate, njenge-extraction solvent yokuhlukanisa ama-alkanes nama-arenes, kanye ne-reaction medium yama-arenes, i-butadiene extraction, i-acrylic fiber, i-plastic solvents, i-organic and synthetic dyes, kanye nezimboni zemithi. Emkhakheni wezokwelapha, i-dimethyl sulfoxide inomphumela wokulwa nokuvuvukala kanye ne-analgesic onamandla okungena esikhumbeni, ngaleyo ndlela ikwazi ukuncibilikisa imithi ethile futhi ikhulise ukungena kwayo emzimbeni womuntu ukuze kufezwe izinhloso zokwelapha. Ukuthatha le mpahla ye-dimethyl sulfoxide kungenza ukuthi isetshenziswe njengezithasiselo ze-pesticide. Ukwengeza inani elincane le-dimethyl sulfoxide kwezinye izibulala-zinambuzane kungasiza ekungeneni kwezibulala-zinambuzane esitshalweni ukuze kuthuthukiswe ukusebenza kahle. I-dimethyl sulfoxide ingasetshenziswa futhi njengesithako sombala, i-ejenti yokususa udayi, kanye nesithwali sombala wemicu yokwenziwa. Ingasetshenziswa futhi njengesimunca i-acetylene kanye ne-sulfur dioxide ephinda isetshenziswe kanye neziguquli ze-fibre yokwenziwa, i-ejenti yokuvimbela ukuqandisa kanye ne-capacitor dielectric, uwoyela wamabhuleki, kanye ne-extractant yezinsimbi ezingavamile.
3. Ingasetshenziswa njengezixazululo zokuhlaziya kanye ne-ejenti yokulungisa i-gas chromatography kanye ne-solvent yokuhlaziya ama-UV spectra.
