Hydroquinone Bis(2-hydroxyethyl) Ether (HQEE): Chemical Properties and Supplier Insights

In the world of specialty chemicals, understanding the precise properties and applications of key compounds is essential for innovation and efficient manufacturing. Hydroquinone Bis(2-hydroxyethyl) Ether (HQEE), with CAS number 104-38-1, is a significant aromatic diol chain extender that has garnered considerable attention for its impact on polyurethane (PU) elastomers and other polymer systems. As a dedicated chemical manufacturer and supplier, we provide comprehensive insights into HQEE, covering its chemical characteristics and its crucial role in various industries.

Key Chemical Properties of HQEE

HQEE (Hydroquinone Bis(2-hydroxyethyl) Ether) is characterized by its symmetrical structure, featuring two hydroxyl (-OH) groups attached to ethyl ether chains linked to a benzene ring. This molecular architecture dictates its functionality and performance:

  • Chemical Formula: C10H14O4
  • Molecular Weight: Approximately 198.22 g/mol.
  • Appearance: Typically presents as an off-white flake or powder.
  • Purity: High purity grades, often exceeding 98%, are standard for optimal performance.
  • Melting Point: Varies slightly based on purity but generally falls around 98-108°C, indicating a stable solid form at room temperature.
  • Hydroxyl Value: A critical parameter for reaction kinetics in PU synthesis, typically in the range of 540-580 mg KOH/g.
  • Solubility: Soluble in certain organic solvents, which is important for formulation processing.

These properties make HQEE an ideal reactant in the synthesis of polyurethanes, where its structure contributes to the formation of hard segments that enhance the overall material properties.

Impact on Polyurethane Elastomers

When manufacturers choose to buy HQEE for their PU formulations, they benefit from:

  • Enhanced Mechanical Strength: Improved tensile strength, hardness, and tear resistance are hallmarks of HQEE-modified polyurethanes.
  • Superior Dynamic Properties: Increased resilience and reduced compression set are crucial for components subjected to cyclical loads.
  • Good Thermal Resistance: The aromatic nature of HQEE provides better stability at elevated temperatures.

These performance enhancements are why HQEE is a preferred chain extender for demanding applications ranging from industrial seals and automotive components to specialized coatings.
