Taupānga
Kei te whakamahia whānuitia te Dimethyl sulfoxide hei whakarewa, tauhohenga tauhohenga me te whakahiato waro hei takawaenga, ina koa ko te tukatuka whakarewa me te kakawaea tuhi whakarewa i roto i te tauhohenga polymerization acrylonitrile, hei whakarewa mo te whakahiato polyurethane me te tuhi kakawaea, hei whakarewa mo te polyamide, polyimide me te kapia polysulfone, me whakarewa mo te tangohanga waiwaro kakara me te butadiene me te whakarewa mo te whakahiato chlorofluoroaniline.I tua atu, ka whakamahia tika te dimethyl sulfoxide hei rauemi mata me te kawe i etahi raau taero i roto i te umanga rongoa.Ko te Dimethyl sulfoxide (DMSO) ano he hua whakaahuru, analgesic, diuretic me te whakarokiroki, e mohiotia ana ano he "panacea", he mea taapiri ki nga raau taero hei waahanga kaha o nga raau taero.
Ko te Dimethyl sulfoxide (DMSO) he pūhui pararopi kei roto he whanariki me te tātai rāpoi C2H6OS, he wai maramara kore tae me te hongi i te pāmahana rūma, me te wai muramura.Kei a ia nga ahuatanga o te polarity teitei, te teitei o te kohua, te pai o te waiariki, te kore-protonic, te whakauru ki te wai, ka whakarewahia i roto i te nuinga o nga matū waro penei i te ethanol, propanol, benzene me te chloroform, me etahi atu e mohiotia ana ko te "whakarewa ao".Ka wera i te aroaro o te waikawa, ka puta he iti o te methyl mercaptan, formaldehyde, dimethyl sulfide, methanesulfonic acid me etahi atu pūhui.Ka pirau i te wera nui, ka kaha te urupare ki te maota, ka wera i te hau me te mura puru marama.Ka taea te whakamahi hei whakarewa pararopi, reo tauhohenga me te takawaenga whakahiato waro.Ka taea hoki te whakamahi hei waikano waikano o te muka waihanga, kaihoko tae, kawe tae me te mimiti mo te whakaora i te acetylene me te sulfur dioxide.
Ngā āhuatanga ā-tinana.
Te wai kirikiri kore tae.He wera, tata kore kakara, he kawa te reka, he hygroscopic.Haunga te hinu ether, ka taea e ia te whakakore i nga whakarewa pararopi whanui.Ka taea te whakarewa i roto i te wai, te waiwaro, te acetone, te acetaldehyde, te pyridine, te ethyl acetate, te dibutyl benzodicarboxylate, te dioxane me nga pūhui kakara, engari karekau i te wairewa i roto i nga pūhui waiwaro aliphatic i tua atu i te acetylene.He kaha te hygroscopicity, a ka taea e ia te tango i te makuku e rite ana ki te 70% o tona ake taumaha mai i te rangi i te 20 ℃ ka 60% te haumākū whanaunga.Ko te hua he oxidizer ngoikore, a ko te dimethyl sulfoxide kaore he wai e kino ki nga konganuku.I te wa e mau ana te wai, ka pirau ki te rino;parahi me etahi atu konganuku, engari kaua ki te konumohe.Ka mau ki nga turanga.Ko te whakamahana i te aroaro o te waikawa ka puta te iti o te methyl mercaptan, formaldehyde, dimethyl sulfide;waikawa methanesulfonika me ētahi atu pūhui.Ko te pirau i te wera nui, ka kaha te urupare ki te maota, ka wera i te rangi me te mura puru marama.
