Dimethyl sulfoxide (DMSO) yog cov kuab tshuaj siv dav, miscible nrog dej thiab ntau cov kuab tshuaj organic.
DMSO yog thawj zaug pom nyob rau hauv lub xyoo pua puv 19 raws li ib tug byproduct ntawm cov ntoo pulp papermaking txheej txheem. Nyob ib ncig ntawm tib lub sijhawm, tus kws tshuaj Lavxias teb sab Alexander Zaitsev tau tsim DMSO los ntawm oxidizing lwm cov khoom ntawm kraft papermaking txheej txheem -dimethyl sulfide. Zaitsev txoj kev sib xyaw ua ke tsim lub hauv paus ntawm DMSO cov txheej txheem tsim khoom tseem siv niaj hnub no.

DMSO Solvent Siv li cas hauv Tshuaj Synthesis?
Dimethyl sulfoxide (DMSO) feem ntau yog siv los ua cov tshuaj tiv thaiv nruab nrab hauv cov organic chemistry vim tias nws dissolves ntau yam reactants thiab tseem siv tau txawm tias cov kuab tshuaj ua tsis tau zoo.
Raws li ib tug polar aprotic hnyav, DMSO stabilizes ions thiab yog zoo tagnrho rau nucleophilic hloov, tshem tawm, thiab lub hauv paus- catalyzed cov tshuaj tiv thaiv, ua kom sai thiab huv si.
DMSO tuaj yeem siv rau cov tshuaj tiv thaiv oxidation me me, hloov cov cawv rau aldehydes lossis ketones yam tsis tas yuav muaj cov tshuaj muaj zog.
Dimethyl sulfoxide dissolves tsis zoo soluble organic tebchaw, yog li kev txhim kho reactant kev sib cuam tshuam thiab nce hluavtaws hloov dua siab tshiab.
Nws yog siv dav hauv kev tsim cov khoom siv siab heev, xws li hluavtaws polymers, cov khoom siv hluav taws xob, thiab cov khoom tshwj xeeb.
Hauv kev lag luam synthesis, DMSO chemicals yog siv rau cov tshuaj electrochemical, kev tshawb fawb roj teeb, thiab catalysis, txhim kho ion thauj thiab cov tshuaj tiv thaiv stability.
Qhov kub kub ntawm DMSO (CAS 67-68-5) (kwv yees li 189 degree) ua rau muaj kev kub ntxhov siab, txo cov evaporation, thiab txhawb kev tsim khoom loj.
DMSO hnyav yog qhov ruaj khov thiab sib haum nrog feem ntau cov kua qaub, cov hauv paus, catalysts, thiab reagents, ua rau nws tsim nyog rau kev sib xyaw ua ke.

Cov ntaub ntawv kev nyab xeeb
Los xyuas kom meej qhov zoo thiab kev nyab xeeb ntawm DMSO tshuaj:
- Khaws rau hauv qhov chaw txias, qhuav, zoo - qhov cua.
- Khaws kom deb ntawm cov muaj zog oxidizers.
- Siv cov thawv ntim airtight los tiv thaiv kev nqus dej.
- Tsis txhob sib cuag ntawm daim tawv nqaij (cov tshuaj tuaj yeem nqus tau los ntawm daim tawv nqaij).
