Understanding the cyclohexane boiling point is crucial for chemists, students, and professionals in industries like pharmaceuticals, chemicals, and materials science. Cyclohexane, a cyclic hydrocarbon with the formula C₆H₆, is widely used as a solvent and in organic synthesis. Its boiling point is a key physical property that influences its applications and handling. This post provides an easy reference value for the cyclohexane boiling point, along with essential information for both informational and commercial audiences.
Cyclohexane Boiling Point: The Easy Reference Value
The cyclohexane boiling point is 80.7°C (177.3°F) at standard atmospheric pressure (1 atm). This value is essential for processes like distillation, purification, and solvent selection. Knowing this property ensures safe and efficient use in laboratory and industrial settings.
Why is the Boiling Point Important?
The boiling point of cyclohexane determines its suitability for specific applications. For instance:
- Solvent Use: Its low boiling point makes it ideal for extracting non-polar substances.
- Chemical Reactions: It allows precise temperature control during reactions.
- Safety: Understanding its boiling point helps prevent accidents like overheating or vaporization.
📌 Note: Always verify boiling points under specific conditions, as pressure and impurities can affect the value.
Factors Affecting Cyclohexane’s Boiling Point
While the standard cyclohexane boiling point is 80.7°C, several factors can alter this value:
1. Pressure Changes
Boiling points decrease with lower pressure and increase with higher pressure. For example:
- At 0.5 atm, cyclohexane boils at approximately 70°C.
- At 2 atm, it boils at around 90°C.
2. Purity of the Substance
Impurities or solvents mixed with cyclohexane can elevate its boiling point. Pure cyclohexane always boils at 80.7°C, but mixtures may require distillation for accurate measurements.
| Condition | Boiling Point (°C) |
|---|---|
| Standard Pressure (1 atm) | 80.7 |
| Reduced Pressure (0.5 atm) | ~70 |
| Elevated Pressure (2 atm) | ~90 |
Practical Applications of Cyclohexane’s Boiling Point
For commercial-intent visitors, understanding the cyclohexane boiling point is vital for optimizing processes and selecting the right products.
Industries That Rely on Cyclohexane
- Pharmaceuticals: Used in drug synthesis and purification.
- Chemical Manufacturing: Acts as a solvent for non-polar compounds.
- Laboratories: Essential for organic chemistry experiments.
How to Use Cyclohexane Effectively
- Distillation: Separate cyclohexane from mixtures using its precise boiling point.
- Solvent Selection: Choose cyclohexane for reactions requiring low boiling points.
- Safety Precautions: Store and handle cyclohexane below 80.7°C to prevent vaporization.
⚠️ Note: Cyclohexane is flammable, so avoid open flames or high temperatures during use.
Quick Checklist for Cyclohexane Handling
- Verify Boiling Point: Always use 80.7°C as the reference value.
- Check Pressure: Adjust for non-standard conditions.
- Ensure Purity: Use pure cyclohexane for accurate results.
