Product Description

Hexamethylenediamine (HMDA) Product Details

Chemical Information

• Chemical Name: Hexamethylenediamine

• Synonyms: 1,6-Hexanediamine, HMDA

• CAS Number: 124-09-4

• Molecular Weight: 116.21 g/mol

Preparation Method

Hexamethylenediamine is commonly prepared through hydrogenation of adiponitrile (ADN):

Reaction:
Adiponitrile + Hydrogen → Hexamethylenediamine
This process is typically catalyzed by nickel-based or cobalt-based catalysts under high pressure and temperature.

 

Applications

1. Nylon 66 Production:

   • Reacts with adipic acid to form nylon 66, used in textiles, automotive, electronics, and engineering plastics.

2. Polyurethane Industry:

   • Acts as a chain extender and cross-linker for producing polyurethane foams, coatings, adhesives, and elastomers.

3. Epoxy Curing Agent:

   • Functions as a curing agent in epoxy resin systems for adhesives, coatings, and composites.

4. Chemical Intermediates:

   • Used in the production of lubricants, biocides, corrosion inhibitors, and surfactants.

5. Water Treatment:

   • Component of specialty chemicals for corrosion and scale control in water systems.

6.  Agrochemical Uses:

   • Intermediate for synthesis of specific drugs and pesticide compounds.
