tlhaloso
Ke e 'ngoe ea litharollo tsa tlhaho tse sebelisoang haholo tse nang le ho qhibiliha ho matla ka ho fetisisa. E ka qhala boholo ba lintho tse phelang, ho kenyeletsoa lik'habohaedreite, li-polymer, li-peptide, le letsoai le likhase tse ngata tse sa tloaelehang. E ka qhala 50-60% ea boima ba eona ba solute (litharollo tse ling tse akaretsang li ka qhala 10-20%) feela, kahoo e bohlokoa haholo tsamaisong ea sampole le tlhahlobong ea lithethefatsi ka lebelo le phahameng. Tlas'a maemo a itseng, karabelo e phatlohang e ka etsahala ha Dimethyl sulfoxide e kopana le acid chloride. Dimethyl sulfoxide e sebelisoa haholo e le solvent le reagent, haholo-holo e le solvent e sebetsanang le solvent le solvent e potolohang ka har'a acrylonitrile polymerization, e le synthesis ea polyurethane le solvent e potolohang, e le polyamide, polyimide le polysulfone resin synthesis Solvents, Chemicalbook le aromatic hydrocarbons, solvents ea butadiene extraction le solvents bakeng sa synthesis ea chlorofluoroaniline, jj. Ho phaella moo, indastering ea meriana, dimethyl sulfoxide le eona e sebelisoa ka ho toba e le thepa e tala le mojari oa meriana e meng. Dimethyl sulfoxide ka boyona e na le ditlamorao tse thibelang ho ruruha le ho imolla bohloko, ho fokotsa ho ruruha, ho kokobetsa le tse ding, tse tsejwang hape e le "panacea", mme hangata e eketswa dithethefatsing e le karolo e sebetsang ya dithethefatsi tse kokobetsang bohloko. E na le thepa e ikgethang ya ho kenella letlalong habonolo haholo, e leng se fellang ka tatso e kang ya oyster ho mosebedisi. Sodium cyanide ho dimethyl sulfoxide e ka baka chefo ya cyanide ka ho kopana le letlalo. Mme dimethyl sulfoxide ka boyona ha e na chefo e kaalo. Dimethyl sulfoxide e sebediswa e le drainage ke boholo ba dikhamphani tsa dikhemikhale le tsa meriana. Leha ho le jwalo, ka lebaka la ntlha e phahameng ya ho belisa ya DMSO, mocheso wa tshebetso o phahame haholo, e leng se lebisang ho hokelleng ha thepa, e leng se amang ho kgutliswa ha dimethyl sulfoxide le ho hlwekisa disebediswa. Eketsa tshebediso ya matla. Ka hona, ho kgutliswa ha DMSO ho fetohile bothata bakeng sa tshebediso ya yona e pharaletseng e le drainage. Dimethyl sulfoxide ke solvent e tlwaelehileng ya aprotic organic e sebediswang ho qhala metsoako ya polar le e seng polar. Sebopeho se se nang sebopeho, DMSO-d6 (D479382), se sebediswang haholoholo bakeng sa dithuto tsa NMR, se ka bonwa habonolo ka bongata ba sona ba NMR ka lebaka la bokgoni ba sona ba ho qhala boholo ba di-analyte.

Litšebeliso tsa DMSO
1. DMSO e sebediswa bakeng sa ho ntsha hydrocarbon e nkhang hamonate, sebaka sa karabelo bakeng sa resin le dae, polymerization ya faeba ya acrylic, le solvent bakeng sa ho ohla, jj.
2. DMSO e ka sebelisoa e le tharollo ea tlhaho, mokhoa oa karabelo le motsoako oa tlhaho. E na le mekhoa e mengata haholo. Sehlahisoa sena se na le bokhoni bo phahameng ba ho ntša lintho tse itseng, se sebelisoa e le tharollo ea polymerization le condensation ea resin ea acrylic le resin ea polysulfone, tharollo ea polymerization le spining ea polyacrylonitrile le acetate fiber, tharollo ea extraction ea alkane le karohano ea hydrocarbon e nkhang hamonate. Hydrocarbon e nkhang hamonate, butadiene extraction, acrylic fiber spining, solvent ea polasetiki le reaction medium bakeng sa lidae tsa maiketsetso tsa organic, meriana le liindasteri tse ling. Mabapi le bongaka, dimethyl sulfoxide e na le litlamorao tse khahlanong le ho ruruha le ho kokobetsa bohloko, 'me e na le matla a matla a ho kenella letlalong, kahoo e ka qhala meriana e itseng ho Chemicalbook, e le hore meriana e joalo e ka kenella 'meleng oa motho ho fihlela sepheo sa kalafo. Ha e sebelisa thepa ena ea mojari oa dimethyl sulfoxide, e ka boela ea sebelisoa e le tlatsetso bakeng sa chefo e bolaeang likokoanyana. Karolo e nyane ea dimethyl sulfoxide e eketsoa ho chefo e bolaeang likokoanyana tse ling ho thusa chefo e bolaeang likokoanyana ho kenella semeleng ho ntlafatsa katleho. Dimethyl sulfoxide e ka boela ea sebelisoa e le solvent ea ho daea, sesebelisoa sa ho tlosa matheba, sesebelisoa sa ho daea bakeng sa likhoele tsa maiketsetso, sesebelisoa sa ho monya acetylene le sulfur dioxide, sesebelisoa sa ho fetola faeba ea maiketsetso, sesebelisoa sa ho thibela ho hoama, sesebelisoa sa capacitor, oli ea brake, sesebelisoa sa ho ntša tšepe e sa tloaelehang, jj.
3.DMSO e ka sebelisoa e le setlolo sa tlhahlobo le mokelikeli o tsitsitseng bakeng sa chromatography ea khase, hape e ka sebelisoa e le tharollo tlhahlobong ea ultraviolet spectrum.
4. DMSO organic solvent, reaction medium le organic synthesis intermediate. E tenyetseha haholo. Ka bokgoni bo phahameng ba ho ntsha dintho, e sebediswa e le polymerization le condensation solvent ya acrylic resin le polysulfone resin, polymerization le spining solvent ya polyacrylonitrile le acetate fiber Chemicalbook, clearing solvent ya extraction ya alkane le sprain hydrocarbon, e sebediswang bakeng sa aromatic hydrocarbon, Butadiene extraction, acrylic fiber spining, solvent ya polasetiki le organic synthetic daes, meriana le di-industrial reaction medium tse ding. Mabapi le bongaka, e na le ditlamorao tse thibelang ho ruruha le ho kokobetsa bohloko, mme e na le ho kenella ho matla letlalong.
