Yog lawm, N,N-Dimethylformamide (CAS: 68-12-2) yog ib qho hnyav hnyav thiab feem ntau hu ua "universal solvent."
Nws qhov tshwj xeeb dissolving zog feem ntau yog los ntawm nws cov polarity muaj zog thiab tsis yog -protonic xwm, ua kom nws yaj ntau yam organic thiab inorganic tebchaw, suav nrog qee cov polymers uas tsis muaj kuab lom heev. Cov yam ntxwv tseem ceeb muaj xws li:
- Extensive Solvent Compatibility:N,N-Dimethylformamide yog miscible nrog dej, cawv, ethers, esters, ketones, halogenated hydrocarbons, aromatics, thiab lwm yam kuab tshuaj. Nws dissolves polymers xws li polyethylene thiab polyvinyl chloride.
- Chemical Properties:Cov carbonyl oxygen thiab nitrogen atoms hauv DMF molecule confer electron - pub cov yam ntxwv, ua rau nws tsim hydrogen bonds nrog solutes. Qhov no ua rau muaj kev cuam tshuam zoo ntawm ob qho tib si polar thiab nonpolar, ua pov thawj tshwj xeeb hauv cov tshuaj lom neeg xws li peptide synthesis thiab tshuaj purification.
- Kev Siv Hluav Taws Xob:Nws cov khoom siv raws li cov kuab tshuaj yog qhov dav tshwj xeeb, ua cov kuab tshuaj tseem ceeb hauv polyacrylonitrile fiber ntau spinning, polyurethane tawv tawv ntau lawm, kev tsim tshuaj, coatings, thiab kev lag luam hluav taws xob.
Yog li ntawd, txawm hais tias kev soj ntsuam los ntawm nws cov khoom siv physicochemical los yog cov ntawv thov kev lag luam, N, N-Dimethylformamide yog cov organic hnyav heev.
Vim li cas thiaj xaiv Gneebio ua koj tus neeg muag khoom?
Raws li ib tugN,N{0}}Dimethylformamide (CAS: 68-12-2) chaw tsim tshuaj paus, Gneebio tsom rau cov khoom sib xws, kev siv tau zoo, thiab kev ntseeg siab ntawm cov khoom siv ntau. Lub tuam txhab ua haujlwm raws li kev tswj hwm nruj nruj kom ntseeg tau tias N, N-Dimethylformamide (CAS: 68-}12-2) ua tau raws li qhov yuav tsum tau muaj ntawm thaj chaw loj thiab kev tsim khoom tas mus li.
Qhov tseem ceeb ntawm kev tsim khoom thiab khoom siv zog muaj xws li:
- Tswj purity qib tsim nyog rau kev lag luam thiab khoom siv
- ruaj khov batch-rau-batch zoo rau ntev- kev yuav khoom
- Muaj peev xwm muab tau los txhawb kev cog lus thiab chaw xaj khoom
- Export -npaj ntim thiab cov ntaub ntawv (COA, SDS, thiab lwm yam)
