Taw qhia
1,8-Diazabicyclo [5.4.0] undec-7-ene, feem ntau hu ua DBU, yog ib qho tseem ceeb organic compound.
Xwm:
1. Cov tsos mob thiab tshwm sim: Nws yog cov kua uas tsis muaj xim thiab pob tshab. Nws muaj qhov muaj zog ammonia tsw thiab muaj zog noo noo nqus.
2. Solubility: Soluble nyob rau hauv ntau yam organic solvents, xws li ethanol, ether, chloroform, thiab dimethylformamide.
3. Kev ruaj ntseg: Nws yog ruaj khov thiab tuaj yeem khaws cia rau lub sijhawm ntev ntawm chav tsev kub.
4. Flammability: Nws yog flammable thiab yuav tsum tau zam kom tsis txhob nkag mus rau hauv qhov hluav taws kub.
Kev siv:
1. Catalyst: Nws yog lub hauv paus muaj zog uas feem ntau siv los ua cov alkaline catalyst hauv cov organic synthesis, tshwj xeeb tshaj yog nyob rau hauv cov tshuaj tiv thaiv condensation, kev hloov pauv, thiab cov tshuaj tiv thaiv cyclization.
2. Ion txauv tus neeg sawv cev: tuaj yeem tsim cov ntsev nrog cov organic acids thiab ua tus neeg sawv cev sib pauv anion, feem ntau siv hauv cov organic synthesis thiab analytical chemistry.
3. Tshuaj reagents: feem ntau siv nyob rau hauv hydrogenation cov tshuaj tiv thaiv, deprotection cov tshuaj tiv thaiv, thiab amine hloov cov tshuaj tiv thaiv catalyzed los ntawm cov hauv paus muaj zog hauv cov organic synthesis.
Txoj kev:
Nws tuaj yeem tau txais los ntawm reacting 2-Dehydropiperidine nrog ammonia. Cov txheej txheem synthesis tshwj xeeb yog cumbersome thiab feem ntau yuav tsum muaj cov organic synthesis laboratory los ua.
Cov ntaub ntawv kev ruaj ntseg:
1. Muaj zog corrosiveness thiab tej zaum yuav ua rau khaus ntawm daim tawv nqaij thiab qhov muag. Thaum siv, cov hnab looj tes tiv thaiv thiab looj tsom iav yuav tsum hnav kom tsis txhob muaj kev sib cuag ncaj qha.
2. Thaum khaws cia thiab siv DBUs, yuav tsum tau tswj kom muaj qhov cua kom zoo kom txo tau cov ntxhiab tsw thiab vapors.
3. Tsis txhob hnov qab txog oxidants, acids, thiab organic compounds, thiab tsis txhob ua haujlwm ze ntawm qhov hluav taws kub.
4. Thaum tuav pov tseg, thov ua raws li cov cai hauv zos thiab cov txheej txheem kev nyab xeeb.
