About This Property Calculator

This tool provides a comprehensive set of thermophysical, safety, and environmental properties for diethyl oxalate. By default, the state-dependent properties like density, viscosity, and heat capacity are calculated at standard conditions of 25 °C (298.15 K) and 1 atm (101325 Pa).

How to Calculate Properties at Different Conditions

You can use the interactive calculator above to compute properties at your desired temperature and pressure. Simply enter your target values in the input fields and click the "Calculate Properties" button. The results table will update with the new values.

For example, to find the density of liquid diethyl oxalate at 50 °C and 2 bar, you would:

  1. Select your preferred unit system (e.g., Metric).
  2. Enter "50" into the Temperature field.
  3. Enter "2" into the Pressure field.
  4. Click "Calculate Properties."

The calculator will then display the updated density and other state-dependent properties for these specific conditions. This functionality is essential for process design, equipment sizing, and safety analysis in chemical engineering.
