• Product description :

  DBU (CAS#6674-22-2)is an organic strong base with unique structure, transparent colorless to light yellow liquid, purity up to 99%, with mild reaction conditions, simplified synthesis steps, product selectivity and high yield, used as a catalyst for the production of polyaminoethanol ethyl ester and other chemicals, such as ammonia and dichloroethane in its presence to generate piperazines, it is an excellent dehydrating agent, epoxy resin hardening agent, rust preventive agent, but also can be formulated with high-level It is an excellent dehydrating agent, epoxy resin hardener, rust preventive agent, and can also formulate advanced corrosion inhibitor. Currently widely used in the production of cephalosporin semi-synthetic antibiotics, also used in organic synthesis reaction and semi-synthetic antimicrobials. It can also be used as resin curing promoter, especially for integrated circuits and electronic parts of the external sealing resin; involved in dehalogenation reaction, dimer and trimer dehalogenation reaction, polymerization process of desulfonic acid, denitration reaction, can be dehydrohalogenation reaction to form olefinic amidine bases, the more important applications, such as: carboxylic acid and alkyl halide esterification reaction and the active methylidene compounds of alkylation and acylation. The regular package is plastic drums, sealed and stored in a cool and dry place.

• Uses :

  It is used as catalyst for the production of polyaminoethanol ethyl ester and other chemical products, such as ammonia and dichloroethane reacting to generate piperazine in its presence, which is an excellent dehydrating agent, epoxy resin hardener, rust
