Daim ntawv thov:

1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) (CAS: 6674-22-2) yog bicyclic amidine puag.Nws yog non-nucleophilic, sterically hindered, tertiary amine puag hauv organic chemistry.Nws tau tshaj tawm tias nws zoo tshaj rau amine catalyst hauv Baylis-Hillman cov tshuaj tiv thaiv.
DBU tuaj yeem siv:
1. DBU yog qhov muaj zog amidinebase.Ua hauj lwm raws li ib tug proton scavenger DBU yog tsuas yog siv raws li ib tug non-nucleophilic puag nyob rau hauv lub synthesis ntawm ntau active tshuaj cov khoom xyaw.
2. DBU yog siv nyob rau hauv cov organic synthesis raws li ib tug catalyst, ib tug complexing ligand, thiab ib tug non-nucleophilic puag.Nws yog siv los ua tus neeg sawv cev tiv thaiv rau kev sib txuas ntawm cephalosporin thiab ua ib qho catalyst rau polyurethane.
3. Raws li catalyst rau carboxylic acid esterification nrog dimethyl carbonate
4. DBU yog siv los ua cov resin curing accelerator (tshwj xeeb tshaj yog rau lub hau npog ntawm kev sib xyaw ua ke thiab cov khoom siv hluav taws xob).
5. Raws li catalyst hauv aza-Michael ntxiv thiab Knovenegal condensation cov tshuaj tiv thaiv
6. DBU yog siv los ua ib qho catalyst hauv kev lag luam polyurethane.Nws yog ib qho nquag nquag, tsis tshua muaj ntxhiab gel catalyst.DBU feem ntau yog siv rau hauv cov xwm txheej catalytic uas yuav tsum muaj cov gels muaj zog, suav nrog cov qauv uas muaj ester cycloisocyanates los yog aliphatic isocyanates, uas yuav tsum muaj cov catalysts muaj zog vim tias lawv tsis tshua muaj zog tshaj li aromatic isocyanates.
7. DBU yog siv rau synthesis ntawm heterocycle thiab tseem ceeb nruab nrab ntawm cov tshuaj thiab tshuaj tua kab los yog organic synthesis ntawm block.
8. Tej zaum yuav siv los ua ib qho catalyst rau dissolution thiab activation ntawm cellulose los ntawm ib tug reversible cov tshuaj tiv thaiv ntawm nws hydroxyl pawg nrog carbon dioxide.Qhov no cellulose yaj system yuav derivatized los tsim cellulose tov esters.
9. DBU yog siv rau hauv kev tsim cov cephalosporin semi-synthetic tshuaj tua kab mob, thiab kuj siv nyob rau hauv kev npaj ntawm deacidification agents, xeb inhibitors, advanced corrosion inhibitors, thiab lwm yam.
