Soo saaraha Qiimaha Wanaagsan Dimethyl Sulfoxide (DMSO) CAS 67-68-5
sharaxaad
Waa mid ka mid ah kuwa ugu badan ee la isticmaalo dareerayaasha dabiiciga ah ee leh milanka ugu xooggan. Waxay milmi kartaa inta badan maadada organic, oo ay ku jiraan karbohaydraytyada, polymers, peptides, iyo cusbo iyo gaasyo badan oo aan organic ahayn. Waxay ku milmi kartaa 50-60% miisaankeeda solute (qallafiyeyaasha kale ee guud kaliya waxay milmi karaan 10-20%), sidaas darteed aad bay muhiim ugu tahay maareynta muunada iyo baaritaanka daroogada xawaaraha sare leh. Xaalado gaar ah, fal-celin qaraxyo ah ayaa dhici kara marka Dimethyl sulfoxide ay taabato chloride acid. Dimethyl sulfoxide waxaa si ballaaran loo isticmaalaa sida dareeraha iyo reagent, gaar ahaan sida dareeraha dareeraha iyo dareeraha miiqinta ee polymerization acrylonitrile, sida polyurethane iyo dareeraha dareeraha ah, sida polyamide, polyimide iyo polysulfone resin synthesis Solvents, Kiimikada iyo hydrocarbons caraf udgoon, dareeraha miiridda butadiene iyo dareerayaasha chloroline ee dheeriga ah warshadaha dawooyinka, dimethyl sulfoxide sidoo kale waxaa si toos ah loo isticmaalaa sida alaabta ceeriin iyo side ee daawooyinka qaarkood. Dimethyl sulfoxide lafteedu waxay leedahay anti-bararka iyo xanuunka yareeya, durayo, suuxin iyo saameyno kale, oo sidoo kale loo yaqaan "panacea", waxaana badanaa lagu daraa daawooyinka sida qayb firfircoon oo ka mid ah daawooyinka xanuunka yareeya. Waxay leedahay hanti gaar ah oo si fudud u dhex marisa maqaarka, taasoo keenta dhadhan u eg lohodka isticmaalaha. Sodium cyanide ee ku jira dimethyl sulfoxide waxa ay keeni kartaa sunta cyanide iyada oo loo marayo taabashada maqaarka. Dimethyl sulfoxide lafteedu way ka yar tahay sunta. Dimethyl sulfoxide waxa loo isticmaalaa soosaar ahaan inta badan shirkadaha kiimikada iyo dawooyinka. Si kastaba ha noqotee, iyadoo ay ugu wacan tahay barta karkarinta sare ee DMSO, heerkulka hawlgalka ayaa aad u sarreeya, taas oo horseedaysa coking alaabta, taas oo saameynaysa soo kabashada dimethyl sulfoxide iyo nadiifinta qalabka. Kordhi isticmaalka tamarta. Sidaa darteed, soo kabashada DMSO waxay noqotay cidhiidhi u sii faafsanaanteeda si baahsan. Dimethyl sulfoxide waa dareere aprotic caadi ah oo loo isticmaalo in lagu milo xeryahooda polar iyo nonpolar. Foomka go'ay, DMSO-d6 (D479382), oo loo isticmaalo ugu horrayn daraasadaha NMR, ayaa si fudud loogu aqoonsan karaa NMR spectrum sababtoo ah awoodda ay u leedahay inay milmaan inta badan falanqaynta.

Codsiyada DMSO
1. DMSO waxaa loo isticmaalaa soo saarista hydrocarbon udgoon, dhexdhexaad ah falcelinta resin iyo dheeha, polymerization fiber acrylic, iyo dareere for milling, iwm.
2. DMSO waxaa loo isticmaali karaa sida dareeraha organic, falcelinta dhexdhexaad ah iyo dhex-abuurka organic dhexdhexaad ah. Aad u kala duwan Alaabtani waxay leedahay awood sare oo wax-soo-saarid ah, oo loo isticmaalo sida polymerization-ka iyo dareeraha uumiga ee resin acrylic iyo polysulfone resin, polymerization iyo millatariga poliacrylonitrile iyo fiber acetate, dareeraha soo saarista alkane iyo kala soocida hydrocarbon udgoon. Hydrocarbon caraf udgoon, soosaarista butadiene, fiilada akrilik, dareere caag ah iyo falcelin dhexdhexaad ah oo loogu talagalay dheeha synthetic organic, daawooyinka iyo warshadaha kale. Dhanka dawada, dimethyl sulfoxide waxa ay leedahay saameyn liddi ku ah bararka iyo xanuunka, waxayna leedahay awood xoog leh oo gelisa maqaarka, sidaas darteed waxay ku milmi kartaa daawooyinka qaarkood ee ku jira buug-yareedka, si daawooyinka noocaas ahi ay u galaan jidhka bini'aadamka si loo gaaro ujeedada daaweynta. Ka faa'iidaysiga hantida sidaha ah ee dimethyl sulfoxide, waxa kale oo loo isticmaali karaa wax lagu daro sunta cayayaanka. Qadar yar oo dimethyl sulfoxide ah ayaa lagu daraa qaar ka mid ah sunta cayayaanka si ay uga caawiso sunta cayayaanka inay dhex gasho geedka si loo hagaajiyo waxtarka. Dimethyl sulfoxide sidoo kale waxaa loo isticmaali karaa sida dareeraha dheeha, wakiilka de-staining, sidaha dheeha ee fiilooyinka synthetic, nuugista soo kabashada acetylene iyo sulfur dioxide, wax ka beddelka fiber synthetic, antifreeze, dhexdhexaad capacitor, saliid brake, saarista wakiilka biraha dhif ah, iwm.
3.DMSO waxaa loo isticmaali karaa sida reagent gorfaynta iyo dareere go'an loogu talagalay chromatography gaaska, iyo sidoo kale loo isticmaalo sida dareere ah ee falanqaynta ultraviolet spectrum.
4.DMSO dareeraha dabiiciga ah, dhexdhexaadinta falcelinta iyo isku-dhafka dabiiciga ah ee dhexdhexaadka ah. Aad u kala duwan Iyada oo awoodda saarista sare ee xulashada, waxaa loo isticmaalaa sida polymerization iyo uumiga dareeraha ah ee resin acrylic iyo polysulfone resin, polymerization iyo dareeraha miiqan ee polyacrylonitrile iyo acetate fiber Chemicalbook, dareeraha soo saaridda ee alkane iyo caraf udgoon kala soocidda, loo isticmaalo hydrocarbon udgoon, Butadiene fiirsato, fiber synthe organic acid dhexdhexaadinta falcelinta dawooyinka iyo warshadaha kale. Dhanka dawada, waxay leedahay saameyn liddi ku ah bararka iyo xanuunka, waxayna leedahay dhexgalka xooggan ee maqaarka.
