DBU CAS 6674-22-2 1,8-Diazabicyclo[5.4.0]undec-7-ene Ịdị ọcha>99.0% (GC) Ụlọ ọrụ

1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) (CAS: 6674-22-2) bụ ntọala amidine bicyclic.Ọ bụ nke na-abụghị nke nucleophilic, sterically egbochi, tertiary amine base na organic kemịkal.A na-akọ na ọ dị elu karịa amine catalyst na mmeghachi omume Baylis-Hillman. Ọ na-akwalite mmeghachi omume methylation nke phenols, indoles na benzimidazoles na dimethyl carbonate n'okpuru ọnọdụ dị nro.
Enwere ike iji DBU:
1. DBU bụ amidinebase siri ike.Ije ozi dị ka proton scavenger DBU ka etinyere ya dị ka ntọala na-abụghị nke nucleophilic na njikọ nke ọtụtụ ihe ọgwụ na-arụ ọrụ.
2. A na-eji DBU mee ihe na nchịkọta organic dị ka ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ bụrụ ihe na-eme ka ọ dị mgbagwoju anya, na-enweghị isi nucleophilic.A na-eji ya dị ka ihe nchebe maka njikọ nke cephalosporin na dị ka ihe na-akpali akpali maka polyurethane.
3. Dị ka ihe na-eme ka esterification carboxylic acid na dimethyl carbonate
4. A na-eji DBU mee ihe dị ka resin curing accelerator (karịsịa maka mkpuchi mpụta nke sekit agbakwunyere na ngwa eletriki).
5. Dị ka ihe na-akpali akpali na mgbakwunye aza-Michael na mmeghachi omume condensation nke Knovenegal
6. A na-eji DBU eme ihe dị ka ihe na-emepụta ihe na ụlọ ọrụ polyurethane.Ọ bụ ihe na-eme ka gel na-arụsi ọrụ ike nke ukwuu.A na-ejikarị DBU eme ihe na ọnọdụ catalytic ebe a na-achọ gels siri ike, gụnyere usoro nwere ester cycloisocyanates ma ọ bụ aliphatic isocyanates, nke na-achọ ihe na-eme ka ọ dị ike n'ihi na ha adịghị arụ ọrụ karịa isocyanates aromatic.
7. A na-eji DBU maka njikọ nke heterocycle na etiti dị mkpa nke ọgwụ na pesticide ma ọ bụ organic njikọ nke ngọngọ.
8. Enwere ike iji ya mee ihe dị ka ihe na-akpali akpali maka mgbasa na ịgbalite cellulose site na mmeghachi omume ntụgharị nke otu hydroxyl ya na carbon dioxide.Enwere ike ịwepụta sistemu cellulose a gbazere ka ọ bụrụ esters agwakọta cellulose.
9. A na-eji DBU eme ihe na-emepụta cephalosporin semi-synthetic antibiotic ọgwụ, ma na-ejikwa na nkwadebe nke deacidification agents, nchara inhibitors, elu corrosion inhibitors, wdg.
