Application:

1,8-Diazabicyclo[5.4.0]undec-7-ene (DBU) (CAS: 6674-22-2) inonzi bicyclic amidine base.Iyo isiri-nucleophilic, yakavharirwa, yepamusoro amine base mune organic chemistry.Inonzi inopfuura amine catalyst muBaylis-Hillman reaction.Inosimudzira methylation reaction ye phenols, indoles uye benzimidazoles ine dimethyl carbonate pasi pemamiriro akareruka.
DBU inogona kushandiswa:
1. DBU is amidinebase yakasimba.Kushanda seproton scavenger DBU inonyanya kushandiswa senge isiri-nucleophilic base mukubatanidzwa kweakawanda anoshanda emishonga emishonga.
2. DBU inoshandiswa mune organic synthesis sechinhu chinokonzeresa, chinoomesa ligand, uye isiri-nucleophilic base.Inoshandiswa sechinhu chinodzivirira chekugadzirwa kwecephalosporin uye sechigadziriso che polyurethane.
3. Sechikonzero che carboxylic acid esterification ine dimethyl carbonate
4. DBU inoshandiswa seresin kuporesa accelerator (kunyanya yevhavha yekunze yemasekete akabatanidzwa uye zvikamu zvemagetsi).
5. Secatalyst mu aza-Michael kuwedzera uye Knovenegal condensation reaction
6. DBU inoshandiswa sechinhu chinokonzera mumhizha ye polyurethane.Iyo inoshanda zvakanyanya, yakaderera-inonhuhwirira gel catalyst.DBU inonyanya kushandiswa mumamiriro ezvinhu anokonzeresa apo majerosi akasimba anodiwa, kusanganisira maumbirwo ane ester cycloisocyanates kana aliphatic isocyanates, ayo anoda macatalyst akasimba nekuti haashande zvakanyanya pane anonhuwirira isocyanates.
7. DBU inoshandiswa pakugadzira heterocycle uye yakakosha yepakati yemishonga uye mushonga wezvipembenene kana organic synthesis ye block.
8. Inogona kushandiswa sechinhu chinokonzera kuparara uye kushandiswa kweselulosi kuburikidza nekugadzirisa maitiro emapoka ayo ehydroxyl ane carbon dioxide.Iyi yakanyungudika cellulose system inogona kutorwa kuti igadzire cellulose yakasanganiswa esters.
9. DBU inoshandiswa mukugadzira cephalosporin semi-synthetic antibiotic drugs, uye inoshandiswawo mukugadzirira kwe deacidification agents, rust inhibitors, advanced corrosion inhibitors, nezvimwewo.
