Isicelo
I-Dimethyl sulfoxide isetyenziswa ngokubanzi njenge-solvent, i-reagent yokuphendula kunye ne-organic synthesis intermediate, ngakumbi njenge-solvent kunye ne-filament drawing ye-solvent kwi-acrylonitrile polymerization reaction, njenge-solvent ye-polyurethane synthesis kunye nomzobo we-filament, njenge-solvent ye-polyamide, i-polyimide kunye ne-polysulfone resin, ngokunjalo isinyibilikisi se-hydrocarbon enevumba elimnandi kunye ne-butadiene yokutsalwa kunye ne-solvent yokudibanisa i-chlorofluoroaniline.Ngaphandle koko, i-dimethyl sulfoxide isetyenziswa ngokuthe ngqo njengento ekrwada kunye nomthwali wamanye amachiza kwishishini lamayeza.I-Dimethyl sulfoxide (i-DMSO) ngokwayo ine-anti-inflammatory, analgesic, diuretic kunye ne-sedative effects, kwaye yaziwa nangokuthi "i-panacea", ehlala yongezwa kwiziyobisi njengenxalenye esebenzayo ye-analgesic drugs.
I-Dimethyl sulfoxide (i-DMSO) yi-sulfure equlethe i-organic compound kunye ne-molecular formula C2H6OS, ulwelo olungenambala kunye ne-odorless transparent kubushushu begumbi, kunye ne-hygroscopic evuthayo.Ineempawu ze-polarity ephezulu, indawo yokubilisa ephezulu, uzinzo oluhle lwe-thermal, i-non-protonic, i-miscible ngamanzi, i-soluble kwizinto ezininzi eziphilayo ezifana ne-ethanol, i-propanol, i-benzene kunye ne-chloroform, njl.Xa kushushu phambi kwe-asidi, inani elincinci le-methyl mercaptan, i-formaldehyde, i-dimethyl sulfide, i-methanesulfonic acid kunye nezinye iikhompawundi ziya kuveliswa.Ibola kwiqondo lokushisa eliphezulu, isabela ngobundlobongela kunye neklorini, kwaye itshisa emoyeni ngedangatye eliluhlaza okwesibhakabhaka.Ingasetyenziswa njenge organic solvent, reaction medium and organic synthesis intermediate.Isenokusetyenziswa njengesinyibilikisi sokudaya sefayibha eyenziweyo, iarhente yokudaya, isithwali sokudaya kunye nesifunxa sokubuyisela iacetylene kunye nesulfure dioxide.
Iimpawu ezibonakalayo.
Ulwelo lwe-viscous olungenambala.Inokutsha, iphantse ingabinavumba, incasa ekrakra, i-hygroscopic.Ngaphandle kwe-ether yepetroleum, inokunyibilikisa izinyibilikisi eziqhelekileyo zendalo.Inokunyibilika emanzini, i-ethanol, i-acetone, i-acetaldehyde, i-pyridine, i-ethyl acetate, i-dibutyl benzodicarboxylate, i-dioxane kunye neekhompawundi ezinevumba elimnandi, kodwa ayinyibiliki kwiikhompawundi ze-aliphatic hydrocarbon ngaphandle kwe-acetylene.Ine-hygroscopicity eyomeleleyo kwaye inokufunxa ukufuma okulingana ne-70% yobunzima bayo ukusuka emoyeni kuma-20℃ xa ukufuma okunxulumeneyo kuyi-60%.Imveliso i-oxidizer ebuthathaka, kwaye i-dimethyl sulfoxide ngaphandle kwamanzi ayinayo i-corrosion to metals.Xa iqulathe amanzi, iyadleka ibe yintsimbi;ubhedu kunye nezinye iintsimbi, kodwa hayi kwi-aluminium.Izinzile kwiziseko.Ukufudumala phambi kwe-asidi kuya kuvelisa inani elincinci le-methyl mercaptan, i-formaldehyde, i-dimethyl sulfide;methanesulfonic acid kunye nezinye iikhompawundi.Ukubola kwiqondo lokushisa eliphezulu, kunokusabela ngobudlova ngeklorini, ukutshisa emoyeni ngedangatye eliluhlaza okwesibhakabhaka.
