Saturated Temperature Formula:
From: | To: |
Definition: This calculator estimates the saturated temperature where liquid and vapor phases coexist in equilibrium using the Antoine equation.
Purpose: It helps chemical engineers and scientists determine phase transition temperatures for various substances.
The calculator uses the formula:
Where:
Explanation: The Antoine equation relates vapor pressure and temperature for pure components.
Details: Accurate saturation temperature prediction is crucial for distillation, evaporation, and other phase-change processes.
Tips: Enter the Antoine constants (A, B, C) for your substance and the pressure. Pressure must be > 0.
Q1: Where can I find Antoine constants?
A: Chemical engineering handbooks or databases like NIST provide Antoine constants for many substances.
Q2: What are typical units for this equation?
A: Temperature in Kelvin, pressure in Pascal, but check your specific Antoine parameters' units.
Q3: What's the temperature range for Antoine equation?
A: Typically valid for 10-150°C, but depends on the substance and parameter source.
Q4: Can I use mmHg instead of Pascal?
A: Yes, but you must use Antoine parameters consistent with your pressure units.
Q5: How accurate is the Antoine equation?
A: Generally within 1-5% for most compounds in their recommended temperature range.
