Umenzi wexabiso elilungileyo iDimethyl Sulfoxide (DMSO) CAS 67-68-5
inkcazelo
Yenye yezona zinto zisetyenziswa ngokuqhelekileyo izinyibilikisi eziphilayo ezinonyibiliko owomeleleyo. Inokunyibilikisa izinto ezininzi eziphilayo, kuquka iicarbohydrates, iipolima, iipeptides, kunye neetyuwa ezininzi kunye neegesi ezininzi. Iyakwazi ukunyibilikisa i-50-60% yobunzima bayo be-solute (ezinye i-solvents eziqhelekileyo zinganyibilika kuphela i-10-20%), ngoko ke kubaluleke kakhulu kulawulo lwesampula kunye nokuhlolwa kweyeza eliphezulu. Phantsi kweemeko ezithile, ukusabela kokudubula kunokwenzeka xa i-Dimethyl sulfoxide idibana ne-acid chloride. I-Dimethyl sulfoxide isetyenziswa ngokubanzi njenge-solvent kunye ne-reagent, ngakumbi njenge-solvent kunye ne-solvent ejikelezayo kwi-acrylonitrile polymerization, njenge-polyurethane synthesis kunye ne-solvent ejikelezayo, njenge-polyamide, i-polyimide kunye ne-polysulfone resin synthesis I-Solvents, i-Chemicalbook kunye ne-hydrocarbons enevumba elimnandi, i-butadiene extraction solvents kunye ne-solvents ye-inchlorosis ye-inchlorosis, njl njl. Ishishini lamayeza, i-dimethyl sulfoxide ikwasetyenziswa ngokuthe ngqo njengemathiriyeli ekrwada kunye nomthwali wamanye amachiza. I-Dimethyl sulfoxide ngokwayo ine-anti-inflammatory and pain-relieving, i-diuretic, i-sedative kunye nezinye iziphumo, ezaziwa ngokuba yi "panacea", kwaye zihlala zongezwa kwiziyobisi njengenxalenye esebenzayo yeziyobisi ezidambisa iintlungu. Inepropathi ekhethekileyo yokugqobhoza ulusu ngokulula, okukhokelela kwincasa efana ne-oyster kumsebenzisi. Isodium cyanide kwi-dimethyl sulfoxide inokubangela ityhefu yecyanide ngokudibana nolusu. Kwaye i-dimethyl sulfoxide ngokwayo ayinayo ityhefu encinci. I-Dimethyl sulfoxide isetyenziswa njenge-extractant ngobuninzi beenkampani zamachiza kunye namayeza. Nangona kunjalo, ngenxa yeqondo eliphezulu lokubilisa le-DMSO, ukushisa okusebenzayo kuphezulu kakhulu, okukhokelela ekuphekeni kwezinto eziphathekayo, ezichaphazela ukubuyiswa kwe-dimethyl sulfoxide kunye nokucoca izixhobo. Ukwandisa ukusetyenziswa kwamandla. Ke ngoko, ukubuyiswa kwe-DMSO kuye kwaba ngumqobo wokusetyenziswa kwayo ngokubanzi njenge-extractant. I-Dimethyl sulfoxide yinto eqhelekileyo ye-aprotic organic solvent esetyenziselwa ukunyibilikisa i-polar kunye ne-nonpolar compounds. I-deuterated form, i-DMSO-d6 (D479382), esetyenziswa ikakhulu kwizifundo ze-NMR, ibonakala lula nge-NMR yayo ngenxa yokukwazi ukunyibilikisa uninzi lwabahlalutyi.

Usetyenziso lwe-DMSO
1. I-DMSO isetyenziselwa i-aromatics hydrocarbon extraction, i-reaction medium ye-resin kunye nedayi, i-acrylic fiber polymerization, kunye ne-solvent for spinning, njl.
2. I-DMSO ingasetyenziswa njenge-solvent ye-organic, i-reaction medium kunye ne-organic synthesis intermediate. Zininzi izinto ezininzi. Le mveliso inekhono eliphezulu lokukhupha, elisetyenziswa njenge-polymerization kunye ne-condensation solvent ye-acrylic resin kunye ne-polysulfone resin, i-polymerization kunye ne-solvent ejikelezayo ye-polyacrylonitrile kunye ne-acetate fiber, i-solvent ye-alkane kunye ne-aromatics hydrocarbon yokwahlukana. I-hydrocarbon enuka kamnandi, i-butadiene extraction, i-acrylic fiber spinning, i-solvent yeplastiki kunye ne-reaction medium ye-organic synthetic idayi, amayeza kunye namanye amashishini. Ngokumalunga neyeza, i-dimethyl sulfoxide ineempembelelo ezichasayo kunye ne-analgesic, kwaye inamandla okungena esikhumbeni, ngoko inokutshabalalisa iziyobisi ezithile kwi-Chemicalbook, ukwenzela ukuba loo mayeza angakwazi ukungena emzimbeni womntu ukufezekisa injongo yokonyango. Ukusebenzisa le propathi yokuthwala i-dimethyl sulfoxide, inokusetyenziswa njengesongezo sokubulala izitshabalalisi. Inani elincinci le-dimethyl sulfoxide liyongezwa kwezinye izibulala-zinambuzane ukunceda i-pesticide ingene kwisityalo ukuphucula ukusebenza kakuhle. I-Dimethyl sulfoxide inokusetyenziswa njenge-solvent yokudaya, i-ejenti ye-de-staining, i-carrier yokudaya ye-synthetic fibers, i-absorbent yokubuyisela i-acetylene kunye ne-sulfur dioxide, i-synthetic fiber modifier, i-antifreeze, i-capacitor medium, i-oyile ye-brake, ukutsalwa kwe-agent yesinyithi enqabileyo, njl.
I-3.DMSO ingasetyenziselwa njenge-reagent analytical kunye ne-fixed liquid ye-chromatography yegesi, kwaye isetyenziswe njenge-solvent kuhlalutyo lwe-ultraviolet spectrum.
I-4.DMSO i-solvent ye-organic, i-reaction medium kunye ne-organic synthesis intermediate. Zininzi izinto ezininzi. Ngobuchule obuphezulu obukhethiweyo bokutsalwa, isetyenziswa njenge-polymerization kunye ne-condensation solvent ye-acrylic resin kunye ne-polysulfone resin, i-polymerization kunye ne-solvent ejikelezayo ye-polyacrylonitrile kunye ne-acetate fiber Chemicalbook, i-solvent ye-alkane kunye ne-aromatic hydrocarbon yokwahlula, esetyenziselwa i-hydrocarbon emnandi, i-Butadiene ye-extraction, i-plastic fiber synthetic amayeza kunye nezinye iindlela zokusabela kushishino. Ngokumalunga neyeza, ineempembelelo ezichasayo kunye ne-analgesic, kwaye inokungena okunamandla kwesikhumba.
