2.2 Chemical Properties
- Molecular structure: Six-member saturated cyclohexane ring with 4-position ethyl group and 1-position hydroxyl group, exists as cis and trans isomer mixture
- Hydroxyl reactivity: Secondary hydroxyl group supports esterification, etherification, oxidation, dehydration reactions for fragrance ester synthesis
- Thermal Stability: Stable below 160℃; high-temperature heating triggers dehydration to generate ethylcyclohexene
- Acid & Alkali Stability: Stable in neutral and weak alkaline environment; dehydration easily occurs under strong acid heating
- Photostability: Slightly pale yellow after long-term air and light exposure, light-proof storage recommended
- Compatibility: Fully compatible with natural essential oils, synthetic fragrances, polar organic solvents; incompatible with concentrated strong acid, strong oxidants
