1. Basic Product Profile
- Full IUPAC Name: 4-Ethylcyclohexan-1-ol
- Aliases: p-Ethylcyclohexanol, 4-Ethyl-1-cyclohexanol
- CAS Number: 4534-74-1
- EINECS: 224-874-4
- Molecular Formula: C8H16O
- Molecular Weight: 128.21
- Chemical Classification: Cycloaliphatic alcohol, fragrance raw material, fine chemical intermediate, solvent
- Core Advantages
Monocyclic saturated cyclohexanol derivative with ethyl substituent at para position, mixture of cis/trans isomers. Delicate woody, green herbal aroma with mild camphor-like undertones, excellent fragrance fixative capacity. Good miscibility with all perfume oils and organic solvents, stable in neutral and weakly alkaline systems. Widely used in daily flavor formulation, organic synthesis intermediates and industrial high-boiling solvent.
2. Physical & Chemical Properties
2.1 Physical Index
- Appearance: Colorless transparent oily liquid
- Odor: Soft woody green fragrance, slight camphor aroma
- Solubility: Slightly soluble in water; miscible with ethanol, methanol, acetone, dipropylene glycol, mineral oil, perfume bases
- Boiling Point: 186–190 °C
- Melting Point: ≤ -5 °C
- Density (20℃): 0.910–0.916 g/cm3
- Refractive Index nD20: 1.455–1.461
- Hygroscopy: Non-hygroscopic
- Volatility: Medium volatility under normal temperature
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
3. Main Application Fields
