Indawo yokuBilisa ye-DMSO: Uhlalutyo oluBanzi kunye noHlalutyo lweSicelo
I-DMSO (i-Dimethyl Sulfoxide) yi-solvent ye-polar organic esetyenziswa ngokubanzi kwiikhemikhali, amayeza, i-biotechnology kunye nezinye iinkalo. Kweli nqaku, siya kuhlalutya iimpawu zamanqaku abilayo e-DMSO ngokweenkcukacha kwaye sixoxe ngezicelo zayo kwiinkalo ezahlukeneyo.
Iipropati ezisisiseko kunye nendawo yokubilisa ye-DMSO
Makhe sijonge kwiimpawu ezisisiseko ze-physicochemical ye-DMSO, engulwelo olungenambala, olungenavumba kunye ne-chemical formula ( \umbhalo{(CH}3)2\text{SO}). Iyaziwa ngokuba yi-solvency egqithisileyo kunye ne-toxicity ephantsi, ikwazi ukutshabalalisa uluhlu olubanzi lwezinto ze-polar kunye ne-non-polar, eziye zakhokelela kwizicelo ezininzi kwiikhemikhali kunye ne-biotechnological fields.
Indawo yokubilisa ye-DMSO yenye yezona zinto zibalulekileyo zomzimba. Ngokwedatha yovavanyo, indawo yokubilisa eqhelekileyo ye-DMSO yi-189 ° C. Eli nqanaba lokubilisa liphezulu ngokwentelekiso lithetha ukuba i-DMSO ihlala ilulwelo kwiqondo lobushushu begumbi kwaye ibonisa uzinzo oluhle lobushushu kwimisebenzi yobushushu obuphezulu. Oku kwenza i-DMSO ibe sisinyibilikisi esiyimfuneko kwiikhemikhali ezininzi zobushushu obuphezulu.
Impembelelo yendawo yokubilisa ye-DMSO kwizicelo zamashishini
Indawo yokubilisa ephezulu ye-DMSO inefuthe elinzulu kwizicelo zayo zoshishino. Kwi-chemical synthesis, indawo yokubilisa yenye yezinto eziphambili ekukhetheni i-solvent, kwaye indawo yokubilisa ye-DMSO ye-189 ° C ithetha ukuba ihlala izinzile kwaye ingabonakali kwiqondo lokushisa eliphezulu, elinenzuzo kwiimpendulo ezininzi ezifuna ukulungiswa kokushisa okuphezulu. Ngokomzekelo, kwi-synthesis yeziyobisi, i-DMSO isoloko isetyenziselwa ukunyibilikisa i-reactants kunye nokuqinisekisa ukuba ukusabela kwenzeka kwiqondo lokushisa elichanekileyo, ngelixa ugwema ukuphuphuma kwangaphambili kwe-solvent ngenxa yeqondo eliphezulu lokubilisa, nto leyo iphucula ukusebenza kakuhle kokuphendula kunye nesivuno semveliso.
Indawo yokubilisa ye-DMSO inika inzuzo kwi-distillation kunye nokwahlula kunye neenkqubo zokucoca. Kule meko, i-DMSO ephezulu yokubilisa inokuthi ifakwe evaporated ukuze isuse ukungcola okuncinci okubilisa, ngaloo ndlela kuphuculwe ukucocwa. Esi sicelo sifumaneka ngokubanzi kwimimandla emihle yeekhemikhali kunye namayeza.
I-DMSO kwilabhoratri
I-DMSO sisinyibilikisi esingenakuthathelwa indawo kuphando lwebhubhoratri ngenxa yeempawu zayo ezizodwa.Inqanaba lokubilisa le-DMSO liyenza ilungele imifuniselo emininzi efuna amaqondo obushushu aphezulu, njengeempendulo ezithile zezinto eziphilayo okanye iimfuniselo zokuphelisa kumaqondo obushushu aphezulu. Izinyibilikisi ezisetyenziswa ngokuqhelekileyo kwibhubhoratri, ezifana ne-ethanol kunye ne-ether, zinendawo yokubilisa ephantsi kakhulu kune-DMSO kwaye ngoko ke ayifanelekanga kwiimvavanyo ezithile zokushisa okuphezulu; Iqondo lokubilisa eliphezulu le-DMSO liqinisekisa ukuba lihlala limanzi kumaqondo obushushu aphezulu kwaye liqinisekisa ukuba imifuniselo yenziwa ngokutyibilikayo.
Ngenxa ye-biocompatibility efanelekileyo kunye neqondo eliphezulu lokubilisa, i-DMSO ikwasetyenziswa ngokuqhelekileyo kwibhayoloji yeseli kunye novavanyo lweziyobisi njenge-solvent ye-carrier okanye ukunyibilikisa amachiza anzima-ukusombulula. Ukudityaniswa kwendawo yokubilisa kunye nokunyibilika kwenza i-DMSO ibe luncedo ngakumbi kule ndawo.
Isishwankathelo
Indawo yokubilisa ye-DMSO (i-189 ° C) yenye yezona zinto ziphawulekayo ezibonakalayo ezibonakalayo, ezingagxininisi kuphela ukusetyenziswa kwayo kwiimpendulo eziphezulu zokushisa, kodwa zichaphazela ukusetyenziswa kwayo ngokubanzi kwimveliso yoshishino kunye nophando lwebhubhoratri. Ukuqonda ukubaluleka kwendawo yokubilisa ye-DMSO kunceda ukusebenzisa ngcono iipropathi zayo ukunyusa iimeko zokusabela kunye nokuphucula iziphumo zovavanyo.
Ngokuhlalutya oku ngasentla, sinokubona ukubaluleka kunye nexabiso lesicelo sendawo yokubilisa ye-DMSO, kunye nokuqonda okunzulu kweempawu zayo ezibonakalayo kuya kunceda kakhulu ukuphuhliswa kakuhle komsebenzi ohambelanayo xa ukhetha kwaye usebenzisa le solvent.
