1, 8-diazabicyclol [5.4.0]undec-7-ene, abbreviated as DBU, is a amidine with a double heterocyclic structure. Its English name is 1, 8-diazabicyclol [5.4.0]undec-7-ene. At room temperature, it is a colorless or light yellow liquid and is soluble in water and ethanol. Many organic solvents such as acetone should generally be stored at temperatures below 30℃.
This product is used as a catalyst in the production of polyurethane and other chemical products. For instance, ammonia and dichloroethane react in its presence to form piperazine. It is an excellent dehydrating agent, a hardener for cyclic oxide resins, a rust inhibitor, and can also be used to formulate high-grade corrosion inhibitors. It is currently widely used in the production of cephalosporin semi-synthetic antibiotics. It is also used in organic synthesis reactions and semi-synthetic antibiotics.
1, 8-diazabicyclodeca-7-ene (DBU) can be used as a catalyst in the production of polyaminomethanol ethyl ester and other chemical products. For instance, ammonia and dichloroethane react in its presence to form piperazine. It is an excellent dehydrating agent, epoxy resin hardener, rust inhibitor, and can be formulated into advanced corrosion inhibitors. It is widely used in the production of cephalosporin semi-synthetic antibiotics. Resin curing accelerator, especially for resins used in the outer packaging of integrated circuits and electronic components; Dehalogenation reaction, dimerization and trimer dehalogenation reaction; Sulfonic acid and nitric acid removal reactions during the polymerization process.
