Isishwankathelo:
I-Dimethyl sulfoxide (i-DMSO efinyeziweyo) yi-organic compound equlathe i-sulfur; ifomula yemolekyuli: (CH3) 2SO; Ibonakala njengolwelo olungenambala, olungenavumba, oluyi-hygroscopic kunye nolunokutsha olunokutsha kubushushu begumbi. Inendawo ephezulu ye-polarity kunye nendawo yokubila ephezulu. Ikwanazo neempawu ze-aprotic kunye ne-water mix. Inobungozi obuphantsi, uzinzo oluhle lobushushu, kwaye ayixutywanga neparafini. Iyanyibilika emanzini, kwi-ethanol, kwi-propanol, kwi-ether, kwi-benzene nakwi-chloroform nakwezinye iintlobo ezininzi zezinto eziphilayo kwaye ibizwa ngokuba yi-"universal solvent." Yi-organic solvent eqhelekileyo enobuchule bokunyibilika obunamandla. Inokunyibilikisa uninzi lwee-organic compounds kuquka ii-carbohydrate, ii-polymers, ii-peptides, kunye neetyuwa ezininzi ze-inorganic kunye neegesi. Inokunyibilikisa isixa esithile se-solute esinobunzima obulingana ne-50-60% yaso (ezinye izinyibilikisi eziqhelekileyo zihlala zinyibilikisa i-10-20%) kuphela, ngoko ke ibaluleke kakhulu ekulawulweni kwesampulu kunye nokuhlolwa kwamayeza ngokukhawuleza okukhulu. Phantsi kweemeko ezithile, ukudibana phakathi kwe-dimethyl sulfoxide kunye ne-chloride kunokukhokelela ekuqhumeni.

Ukusetyenziswa
1. Ingasetyenziselwa ukukhutshelwa kwe-arene, ikwasetyenziswa njengendlela yokusabela esetyenziselwa iiresini kunye needayi, kwaye isetyenziswe kwi-acrylic polymerization kunye ne-spinning solvent.
2. Ingasetyenziswa njengesinyibilikisi sendalo, i-reaction medium kunye ne-intermediates ye-organic synthesis. Iguquguqukayo kakhulu. Le mveliso inomthamo wokukhupha okhethiweyo kakhulu, kwaye ingasetyenziswa njenge-polymerization kunye ne-condensation solvent ye-acrylic resin kunye ne-polysulfone resin, njenge-polymerization kunye ne-spinning solvent ye-polyacrylonitrile kunye ne-cellulose acetate, njenge-extraction solvent yokwahlula i-alkanes kunye ne-arenes, kwaye njenge-reaction medium ye-arenes, i-butadiene extraction, i-acrylic fiber, i-plastic solvents, i-organic kunye ne-synthetic dyes, kunye namashishini e-pharmaceuticals. Kwicandelo lezonyango, i-dimethyl sulfoxide ine-anti-inflammatory kunye ne-analgesic effect enamandla okungena eluswini, kwaye ngaloo ndlela ikwazi ukunyibilikisa amayeza athile kwaye inyuse ukungena kwawo emzimbeni womntu ukuze kufezekiswe iinjongo zonyango. Ukuthatha le propati ye-carrier ye-dimethyl sulfoxide kunokuyenza isetyenziswe njengezongezo ze-pesticide. Ukongeza inani elincinci le-dimethyl sulfoxide kwezinye izibulali-zinambuzane kunokwenza kube lula ukungena kwezibulali-zinambuzane kwisityalo ukuze kuphuculwe ukusebenza kakuhle. I-dimethyl sulfoxide ingasetyenziswa njengesinyibilikisi sedayi, iarhente yokususa idayi, kunye nesithwali sedayi kwiifayibha zokwenziwa. Ingasetyenziswa kwakhona njengesifunxi se-acetylene ephinda isetyenziswe kunye ne-sulfur dioxide kunye neziguquli zefayibha zokwenziwa, iarhente yokuthintela ukukhenkceza kunye ne-capacitor dielectric, ioyile yebrake, kunye ne-extractant yeentsimbi ezinqabileyo.
3. Ingasetyenziswa njengezinyibilikisi zohlalutyo kunye nearhente yokulungisa i-gas chromatography kunye nesinyibilikisi sokuhlalutya ii-UV spectra.
