2-Ethylhexanol (2-EH) Industrial Grade CAS 104-76-7
2-Ethylhexanol (2-EH, CAS 104-76-7) is a branched-chain primary alcohol produced by aldol condensation of butyraldehyde followed by hydrogenation. It is a clear, colorless liquid with a mild odor, miscible with most organic solvents and essentially insoluble in water. Gnee Bio supplies industrial grade 2-ethylhexanol at 99% purity as a plasticizer feedstock and low-volatility solvent.

Applications
1. Plasticizers for PVC
2-Ethylhexanol is used to make plasticizers for polyvinyl chloride. Reaction with phthalic anhydride gives bis(2-ethylhexyl) phthalate (DOP/DEHP); reaction with adipic acid gives bis(2-ethylhexyl) adipate.
2. Acrylate Esters
Esterification with acrylic acid gives 2-ethylhexyl acrylate, used in adhesives and paints.
3. Low-Volatility Solvent
Because it dissolves many organic materials well, 2-ethylhexanol is widely used as a low-volatility solvent in coatings and industrial processes.
Handling and Storage
- 2-EH is combustible (flash point approximately 85 °C); keep away from open flame and store in a cool, ventilated area.
- Keep containers tightly sealed to prevent contamination.
- Use protective gloves and eye protection; refer to the SDS before handling.
Frequently Asked Questions
Q: What is 2-ethylhexanol used for?
A: It is the key feedstock for DOP/DEHP and other plasticizers for PVC, for 2-ethylhexyl acrylate used in adhesives and paints, and for adipate esters; it also serves as a low-volatility solvent.
Q: What is the purity of industrial grade 2-EH?
A: Our industrial grade 2-ethylhexanol is supplied at 99% purity, with the exact values stated on the Certificate of Analysis.
Q: Is 2-ethylhexanol flammable?
A: 2-EH is combustible with a flash point of approximately 85 °C; handle away from open flame and follow the SDS.
Q: Is 2-EH miscible with water?
A: No. 2-ethylhexanol has negligible solubility in water but is miscible with most organic solvents.
