In the chemical industry, understanding the precise properties and applications of key compounds is vital for innovation and product development. 2,2-Dimorpholinodiethylether, commonly known by its acronym DMDEE and identified by CAS number 6425-39-4, is a significant amine catalyst widely employed in polyurethane (PU) formulations. This article delves into its chemical characteristics and its broad spectrum of applications, offering insights for R&D scientists and procurement specialists. We, as a dedicated chemical provider, aim to elucidate the value of this compound.

DMDEE is characterized by its molecular formula C12H24N2O3 and a molecular weight of approximately 244.33 g/mol. It typically appears as a colorless to light yellow liquid, with a purity often exceeding 99.0%. Its physical properties, such as a low melting point (-28 °C) and a relatively high boiling point (309 °C), along with a density of 1.06 g/mL at 25 °C, make it suitable for various industrial processing conditions.

Key Chemical Properties of DMDEE:

  • Appearance: Colorless to light yellow liquid.
  • Purity: Typically ≥99.0% (GC).
  • Melting Point: -28 °C.
  • Boiling Point: 309 °C (lit.).
  • Density: 1.06 g/mL at 25 °C.
  • Solubility: Miscible with water and soluble in many organic solvents.
  • Reactivity: Acts as a tertiary amine catalyst, promoting reactions in polyurethane systems.

The catalytic activity of DMDEE is primarily leveraged in polyurethane chemistry. It efficiently catalyzes the reactions between isocyanates and hydroxyl groups (gelling reaction) and between isocyanates and water (blowing reaction). This dual functionality makes it highly valuable for tailoring the physical properties of PU foams, coatings, adhesives, and elastomers.

Diverse Applications Driven by DMDEE's Catalytic Power:

  • Polyurethane Foams: DMDEE is a strong blowing catalyst, essential for producing flexible, rigid, and semi-rigid polyurethane foams. It aids in achieving the desired cell structure, density, and dimensional stability in products ranging from insulation panels to furniture cushioning. Manufacturers can rely on a consistent supplier for this crucial component.
  • Coatings and Adhesives: In polyurethane coatings and adhesives, DMDEE accelerates curing, leading to faster drying times and improved mechanical properties such as hardness and adhesion. Its use ensures durable and high-performance finishes and bonds.
  • CASE Materials: For Coatings, Adhesives, Sealants, and Elastomers, DMDEE's controlled reactivity profile and ability to enhance component stability make it an ideal catalyst. It contributes to improved application properties and the longevity of the final products.
  • Chemical Synthesis: Beyond its role in PU, DMDEE can also serve as an intermediate or catalyst in other fine chemical synthesis pathways.
