Cov khoom lag luam
N, n-DMFFormamide (DMF) yog cov kua hauv cov pob tshab uas tsis ua haujlwm nrog dej thiab feem ntau cov kuab tshuaj. Nws yog cov kuab tshuaj uas zoo ib txwm muaj rau cov tshuaj lom neeg. Ntshiab ntshiab dimethylformamide muaj cov ntxhiab tsw tshwj xeeb, thaum muaj qhov tsis hnov ntses dim vim tias nws muaj impurities ntawm dimethylamine. Nws yog polar (hydrophilic) tsis muaj zog nrog lub siab npau npau, uas tuaj yeem txhawb nqa tus sn2 cov tshuaj ntsuam.
Teb ntawm daim ntawv thov
- N, n-dimethylformamide yog ib feem siv siv organic huab cua nrog cov kuab heev thiab kev ruaj khov zoo. Nws muaj ntau cov kev siv hauv thaj chaw ntawm chemistry.
- DMF feem ntau siv los ua cov kuab tshuaj hauv cov synthic synthesis. Nws txoj kev ua tau zoo solubility zoo, tuaj yeem yaj ntau cov organic cov tshuaj tiv thaiv yog siv ntau yam organic cov tshuaj tiv thaiv tau los npaj cov tshuaj enses, thiab cov duab kos uas muaj ntxhiab los npaj cov lus teb thiab lwm yam.
- Thib ob, nws tseem siv rau kev lag luam polymer. Nws tuaj yeem siv los ua cov tshuaj tiv thaiv cov tshuaj tiv thaiv rau cov khoom sib xyaw ua ke thiab polyurethane, polyamides, thiab lwm yam. Xim thiab pleev xim.
- Ib qho ntxiv, n, n-n-dimethylformamide tuaj yeem siv los ua electrolyte kuab. Nrog nws cov polarity thiab ruaj khov, nws tuaj yeem siv ua electrolyte kuab nyob rau hauv cov khoom siv xws li cov roj teeb lithium-ion thiab lub hnub ci.
- Nyob rau hauv kev npaj ntawm nanomaterials, nws tuaj yeem siv ua cov kuab tshuaj lossis tshuaj tiv thaiv nruab nrab rau cov synthesis ntawm nanomleations nrog kho cov me me thiab morphology.
Tuam txhab tau
Hauv kaum xyoo dhau los, GNEE tau pab peb cov neeg tau ua tiav ntau txhiab tus ntawm ntau lub teb chaws thoob ntiaj teb, thiab peb tau mus rau ntau lub teb chaws thoob plaws ntiaj teb, Asmeskas, Tebchaws Is Nrias teb, Poland thiab lwm yam. Txoj kev vam meej ntawm cov phiaj xwm no tau muab cov kev tsim kho kom muaj zog rau peb kom muaj zog engineabities thiab peb muaj kev ntseeg siab rau peb cov neeg tau txais txiaj ntsig zoo.
