Diisopropyl azodicarboxylate (DIAD) is an important organic chemical intermediate, and its market demand has continued to grow in recent years. Its main uses include:
1. Foaming agent
Diisopropyl azodicarboxylate is a liquid foaming agent for vinyl resin, especially suitable for preparing light colored vinyl foam. Its decomposition temperature range is wide (40~120 ℃), its gas generation is high, and its decomposition products are non-toxic and pollution-free, so it is widely used in the production of closed or open cell foam bodies in the plastic industry.
2. Crosslinking agents and plasticizers
-In the rubber industry, DIAD, as a crosslinking agent, can enhance the elasticity, wear resistance, and aging resistance of rubber products, and is widely used in fields such as tires and seals.
-In the plastic industry, it can also serve as a heat stabilizer to improve the heat resistance and durability of materials such as polyvinyl chloride (PVC).
3. Coatings and pigment dispersants
As a dispersant in the coatings industry, DIAD can enhance the coverage, adhesion, and weather resistance of coatings, making it suitable for high-end fields such as architectural coatings and automotive coatings.
4. Pharmaceutical intermediates and organic synthesis reagents
In the pharmaceutical field, DIAD is used for synthesizing pharmaceutical intermediates; In organic synthesis, its reaction with phosphorus compounds can prepare phosphorus ylides, which are widely used in complex molecular synthesis.
5. Application of New Energy and Environmental Protection
In recent years, the application of DIAD in the field of new energy has gradually expanded, such as as as an additive in battery materials to improve stability, or as a catalyst to promote organic waste degradation and promote green and environmentally friendly production.
