- Molecular Formula: C15H20O6
- Molecular Weight: 296.32 g/mol
2. Physical Properties
- Appearance: Clear, colorless to pale yellow viscous liquid.
- Odor: Mild, characteristic, acrylic/ester-like.
- Melting Point: <-20 °C (<-4 °F)
- Boiling Point: >200 °C (>392 °F) at 1 hPa (Decomposes at higher temperatures)
- Density: 1.10 - 1.12 g/cm³ at 20 °C
- Solubility:
- In Water: < 0.1 g/L at 20 °C (Insoluble)
- In Organic Solvents: Soluble in many common organic solvents (e.g., acetone, esters, ketones).
- Vapor Pressure: <0.01 hPa at 20 °C
- Viscosity: 80 - 120 mPa·s at 25 °C
3. Chemical Properties and Stability
- Stability: Stable under recommended storage conditions. Typically supplied with a polymerization inhibitor (e.g., MEHQ).
- Incompatibilities: Incompatible with strong oxidizing agents, strong bases, strong acids, reducing agents, peroxides, and free-radical initiators.
- Hazardous Polymerization: May occur if not properly inhibited or if exposed to high temperatures, direct sunlight, UV radiation, or contaminants. Polymerization is a highly exothermic reaction and can be rapid and violent.
- Hazardous Decomposition Products: Combustion may produce toxic fumes of carbon monoxide (CO) and carbon dioxide (CO2).
