Applications

Diamines are an important class of chemicals that are widely used as raw materials, intermediates or products. For example, diamines are important structural units in the synthesis of polyamide and other condensation polymerization reactions. N,N-dimethyl-Chemicalbook1,3-diaminopropane (DMAPA) is an important intermediate, used for example in the industrial preparation of lubricants. In addition, DMAPA is used as a raw material for the preparation of coagulants and itself should have Anti-corrosion properties.
