Isicelo
I-Dimethyl sulfoxide isetshenziswa kabanzi njenge-solvent, reagent yokusabela kanye ne-organic synthesis intermediate, ikakhulukazi njengokucubungula i-solvent kanye ne-filament drawing solvent ku-acrylonitrile polymerization reaction, njenge-solvent ye-polyurethane synthesis kanye nomdwebo we-filament, njenge-solvent ye-polyamide, i-polyimide ne-polysulfone resin, kanye i-solvent ye-hydrocarbon enephunga elimnandi ne-butadiene isizinda kanye ne-solvent yokuhlanganisa i-chlorofluoroaniline.Ngaphandle kwalokho, i-dimethyl sulfoxide isetshenziswa ngokuqondile njengempahla eluhlaza kanye nomthwali weminye imithi embonini yezemithi.I-Dimethyl sulfoxide (DMSO) ngokwayo ine-anti-inflammatory, analgesic, diuretic and sedative effects, futhi yaziwa nangokuthi "i-panacea", evame ukungezwa emithini njengengxenye esebenzayo yezidakamizwa ezidambisa ubuhlungu.
I-Dimethyl sulfoxide (DMSO) iyinhlanganisela ephilayo equkethe isulfur enefomula yemolekyuli i-C2H6OS, uketshezi olusobala olungenambala nolungenaphunga ezingeni lokushisa legumbi, kanye noketshezi oluvutha umlilo olushisayo.Inezici ze-polarity ephezulu, indawo yokubilisa ephezulu, ukuzinza okuhle kokushisa, okungeyona i-protonic, ingxubevange yamanzi, encibilika ezintweni eziningi eziphilayo njenge-ethanol, i-propanol, i-benzene ne-chloroform, njll. Yaziwa ngokuthi "i-solvent yonke indawo".Lapho kushisa phambi kwe-asidi, kuzokhiqizwa inani elincane le-methyl mercaptan, i-formaldehyde, i-dimethyl sulfide, i-methanesulfonic acid nezinye izinhlanganisela.Ibola ngokushisa okuphezulu, isabela ngobudlova ne-chlorine, futhi ishise emoyeni ngelangabi eliluhlaza okwesibhakabhaka.Ingasetshenziswa njenge-solvent ephilayo, i-reaction medium kanye ne-organic synthesis intermediate.Ingasetshenziswa futhi njenge-solvent yokudaya ye-synthetic fiber, i-ejenti yokudaya, isithwali sokudaya kanye nokumunca ukubuyisela i-acetylene ne-sulphur dioxide.
Izici ezingokomzimba.
Uketshezi lwe-viscous olungenambala.Ivutha, cishe ayinaphunga, inokunambitheka okubabayo, i-hygroscopic.Ngaphandle kwe-petroleum ether, ingancibilikisa izinyibilikisi ezivamile zemvelo.Ingancibilika emanzini, i-ethanol, i-acetone, i-acetaldehyde, i-pyridine, i-ethyl acetate, i-dibutyl benzodicarboxylate, i-dioxane nezinhlanganisela ezinuka kamnandi, kodwa engancibiliki kumakhompawundi we-aliphatic hydrocarbon ngaphandle kwe-acetylene.Ine-hygroscopicity eqinile futhi ingakwazi ukumunca umswakama olingana no-70% wesisindo sayo kusuka emoyeni ngo-20℃ lapho umswakama ohlobene ungama-60%.Umkhiqizo uyi-oxidizer ebuthakathaka, futhi i-dimethyl sulfoxide ngaphandle kwamanzi ayigqwali ezinsimbi.Lapho equkethe amanzi, konakala ensimbi;ithusi nezinye izinsimbi, kodwa hhayi ku-aluminium.Izinzile kuya ezisekelweni.Ukushisa phambi kwe-asidi kuzokhiqiza inani elincane le-methyl mercaptan, i-formaldehyde, i-dimethyl sulfide;i-methanesulfonic acid nezinye izinhlanganisela.Ukubola emazingeni okushisa aphezulu, kungasabela ngobudlova nge-chlorine, kuvutha emoyeni ngelangabi eliluhlaza okwesibhakabhaka.
