1,6-Hexanediol[2]
Overview
1,6-Hexanediol is a linear diol with six carbon atoms, widely recognized for its versatility in industrial chemistry. It is a key intermediate in the production of polyurethanes, plasticizers, and adhesives, owing to its bifunctional hydroxyl groups that facilitate polymerization reactions. The compound is valued for its stability, low toxicity, and compatibility with various solvents. In addition to its industrial uses, 1,6-Hexanediol serves as a building block for specialty chemicals, including coatings, resins, and lubricants. Its balanced properties make it suitable for applications requiring high-performance materials with durability and flexibility.
Physical and Chemical Properties
1,6-Hexanediol exhibits a melting point of 42-45°C and a boiling point of 250-253°C, making it stable under a wide range of temperatures. Its density is approximately 0.96 g/cm³ at 25°C, and it is soluble in water, alcohols, and most organic solvents. The compound's low volatility and high boiling point contribute to its utility in high-temperature processes. The diol's hydroxyl groups enable it to participate in esterification and etherification reactions, forming polymers and other derivatives. Its chemical stability and non-reactive nature under normal conditions make it a reliable choice for industrial applications.
Main Applications
1,6-Hexanediol is primarily used in the production of polyurethanes, where it acts as a chain extender or crosslinker, enhancing the material's mechanical properties. It is also employed in plasticizers to improve flexibility and durability in PVC and other polymers. The compound's solvency makes it ideal for adhesives and coatings, providing strong bonding and resistance to environmental factors. Other applications include its use in lubricants, where it reduces friction and wear, and in specialty chemicals for the synthesis of fragrances and pharmaceuticals. Its versatility extends to the textile industry, where it serves as a softening agent for synthetic fibers.
Safety and Storage
While 1,6-Hexanediol is considered low in toxicity, proper handling is essential to avoid skin, eye, or respiratory irritation. Personal protective equipment (PPE), such as gloves and goggles, should be worn during handling. The compound should be stored in a cool, dry, well-ventilated area, away from heat sources and open flames to prevent combustion. In case of spills, absorb the material with an inert substance and dispose of it according to local regulations. Avoid direct contact and ensure adequate ventilation in storage and workspaces to minimize exposure risks.
B2B Procurement Guide
When procuring 1,6-Hexanediol, buyers should prioritize suppliers with certifications such as ISO or REACH compliance to ensure quality and regulatory adherence. Key factors to consider include purity levels (typically 98-99%), packaging options (drums, totes, or bulk), and logistical support for timely delivery. Price fluctuations may occur due to raw material availability and market demand. Establishing long-term contracts with reliable suppliers can mitigate cost variability. Additionally, buyers should verify technical specifications and request safety data sheets (SDS) to ensure compliance with workplace safety standards.
