1,6-Hexanediol is an organic intermediate with a wide spectrum of uses in the chemical industry. Important applications are in the plastics industry, where 1,6-hexanediol is used as additive or hardener and cross linking agent for the synthesis of polyesters, high temperature polymers, polyacrylates or polyurethanes. The production of glues and adhesives, lacquers, synthetic lubricants, textile coatings, surfactants and softening agents, dyestuffs, printing inks, and pharmaceutical active ingredients are other important applications of 1,6-hexanediol. Typical reactions of 1,6-hexanediol are such with mono or dicarbonic acids, diisocyanates, carbonates or phosgene. LANXESS offers 1,6-hexanediol from its production site at Krefeld-Uerdingen as solidified melt as well as liquid in road tankers, tank containers and drums.
Advantages of 1,6-hexanediol as intermediate:
- Compared to other diols, the primary positions of the hydroxyl groups in 1,6-hexanediol lead to an acceleration of the polymerization.
- 1,6-Hexanediol provides hardness and flexibility to plastics and effects enhanced adhesion in glues and adhesives.
- Dyestuffs and coatings based on 1,6-hexanediol are characterised by an improved light fastness and a very small susceptibility to hydrolysis.
Chemical and physical properties:
At room temperature, 1,6-hexanediol is a white to slightly yellow solid. Above 42 °C it melts to a colourless to slightly yellow liquid. 1,6-Hexanediol has an unlimited miscibility with water and common organic solvents. 1,6-Hexanediol is characterised by very low toxicity and a high ignition temperature (335 °C), which allows a convenient handling of the material.
