Introduction
1. Physicochemical Properties
- Structure: A bicyclohexyl framework with a pentyl group at the 4-position of one cyclohexane ring and a nitrile group at the 4-position of a phenyl ring attached to the other cyclohexane ring, both in the trans configuration.
- Molecular Formula: C₁₈H₂₅N
- Molecular Weight: 255.40 g/mol
- Physical Characteristics:
- Appearance: White to almost white solid
- Melting Point: 30-55°C
- Flash Point: 113°C
- Density: Approximately 0.97 g/cm³
2. Synthesis Method
The compound is likely synthesized via substitution reactions involving the introduction of a pentyl group onto one cyclohexane ring and a nitrile group onto a phenyl ring attached to the other cyclohexane ring. Specific methods may include:
- Alkylation of cyclohexane to introduce the pentyl group.
- Cyanation of the phenyl ring to introduce the nitrile group.
- Purification: Chromatography or recrystallization to isolate the trans isomer.
3. Applications
Liquid Crystals: The rigid bicyclohexyl structure and long alkyl chain make it a candidate for liquid crystal materials, where it could influence molecular alignment and optical properties.
4. Safety Information
- Handling: Follow standard chemical safety protocols (e.g., use gloves, goggles, and fume hoods). Avoid skin contact and inhalation.
- Storage: Keep in a cool, dry place, away from oxidants and strong acids.
- Disposal: Consult local regulations for hazardous waste disposal.
Hazard Information:
- GHS Classification: Harmful (Xn)
