1. What is Saturated Temperature using Antoine Equation?

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.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( T_{sat} \) — Saturated temperature (Kelvin)
• \( A \) — Antoine equation constant, A (dimensionless)
• \( B \) — Antoine equation constant, B (Kelvin)
• \( C \) — Antoine equation constant, C (Kelvin)
• \( P \) — Pressure (Pascal)

Explanation: The Antoine equation relates vapor pressure and temperature for pure components.

3. Importance of Saturated Temperature Calculation

Details: Accurate saturation temperature prediction is crucial for distillation, evaporation, and other phase-change processes.

4. Using the Calculator

Tips: Enter the Antoine constants (A, B, C) for your substance and the pressure. Pressure must be > 0.

5. Frequently Asked Questions (FAQ)

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.
