What is Dioctyl ether?
Dioctyl ether (CAS 629-82-3), also known as octyl ether or dicaprylyl ether, is a long-chain symmetrical ether.
Where is Dioctyl ether used?
- Metalworking and industrial lubrication: base fluid or additive component
- Cutting oils and release agents: thermal resistance and low volatility
- Plastics processing: plasticizer or softener for flexibility
- Coatings and adhesives: carrier solvent aiding film formation and viscosity control
- Sealants and elastomers: surface tack modifier and open-time extender
- It improves processability in polymer compounds.
Commercial specifications
- Technical grade, purity typically 97% or higher
- High-purity grades for research and specialty formulation
- Clear liquid in drums and IBCs; bulk availability depends on supplier capacity
