Standard Normal Boiling Point of Octane:
| From: | To: |
The normal boiling point of octane is 125.6°C. This is the temperature at which the vapor pressure of liquid octane equals the atmospheric pressure at sea level (1 atmosphere).
The boiling point is determined through experimental measurement and is a fixed physical property of the substance:
This value represents the standard normal boiling point of pure octane under standard atmospheric conditions.
Details: Knowing the boiling point of octane is crucial for various industrial processes, chemical engineering applications, laboratory work, and understanding the physical properties of hydrocarbons in the petroleum industry.
Tips: Simply click the "Calculate" button to display the standard normal boiling point of octane. No additional input is required as this is a fixed physical property.
Q1: Why is the boiling point of octane important?
A: The boiling point helps in separation processes during petroleum refining and is important for understanding the behavior of octane in various applications.
Q2: Does the boiling point change with pressure?
A: Yes, boiling point decreases with decreasing pressure and increases with increasing pressure. The value 125.6°C is specifically for normal boiling point at 1 atmosphere.
Q3: How does octane's boiling point compare to other alkanes?
A: Boiling point increases with chain length in alkanes. Octane (C8H18) has a higher boiling point than heptane (98°C) but lower than nonane (151°C).
Q4: Can this value be used for octane isomers?
A: This value is for n-octane. Different isomers of octane may have slightly different boiling points due to variations in molecular structure.
Q5: Is this value accurate for all conditions?
A: This is the standard value measured under controlled laboratory conditions. Actual boiling may vary slightly depending on purity and measurement conditions.
