Taw qhia
4,4-Dimethyl-3,5,8-trioxabbicyclo[5,1,0]octane. Nov yog qee yam ntawm nws cov khoom, kev siv, kev tsim khoom, thiab cov ntaub ntawv kev nyab xeeb:
Zoo:
- Cov tsos: cov kua tsis muaj xim.
- Insoluble hauv dej, soluble hauv cov kuab tshuaj organic xws li ethanol thiab dimethylformamide.
Siv:
- DXLO yog dav siv los ua cov tshuaj tiv thaiv nruab nrab thiab catalyst.
- Vim nws cov qauv cyclic tshwj xeeb, nws tuaj yeem siv los ua kom muaj ntau yam kev sib txuas ntawm cov organic.
- Nyob rau hauv lub tshav pob ntawm cov organic synthesis, nws yuav siv tau los npaj cyclic compounds thiab polycyclic aromatic compounds.
Txoj kev:
- DXLO feem ntau yog npaj los ntawm oxanitrile cov tshuaj tiv thaiv. Txoj kev tshwj xeeb yog ua rau dimethyl ether nrog trimethylsilyl nitrile nyob rau hauv acidic tej yam kev mob.
Cov ntaub ntawv kev nyab xeeb:
- DXLO yog suav tias yog ib qho chaw muaj kev nyab xeeb nyob rau hauv cov xwm txheej dav dav, tab sis cov hauv qab no tseem ceeb heev kom paub txog:
- Nws yog cov kua uas muaj nplaim taws thiab yuav tsum tau muab cia rau hauv qhov chaw txias, qhov cua zoo, kom deb ntawm cov nplaim taws thiab qhov kub thiab txias.
- Kev sib cuag nrog daim tawv nqaij thiab qhov muag yuav ua rau khaus thiab yuav tsum zam. Nyob rau hauv rooj plaub uas tsis sib cuag, yaug tam sim ntawd nrog dej ntau.
- Rau lwm cov ncauj lus kom ntxaws txog kev nyab xeeb, Daim Ntawv Qhia Kev Nyab Xeeb thiab Phau Ntawv Qhia Kev Ua Haujlwm yuav tsum raug tshuaj xyuas ua ntej siv tshwj xeeb.
