COSMOlogic COSMOthermX 21.0​


COSMOlogic COSMOthermX 21.0 crack download working​

COSMOthermX 21.0 is a powerful software tool primarily used in the field of chemical engineering, physical chemistry , and process simulation for predicting thermodynamic properties of chemical mixtures using the COSMO-RS (Conductor-like Screening Model for Real Solvents) methodology.

COSMOlogic COSMOthermX 21.0

Developed by COSMOlogic GmbH & Co. KG (a company now part of BIOVIA , a Dassault Systèmes brand), COSMOthermX allows scientists and engineers to calculate thermodynamic data such as:


  • Vapor-liquid equilibria (VLE)
  • Liquid-liquid equilibria (LLE)
  • Activity coefficients
  • Partition coefficients (logP)
  • Solubilities
  • pKa values
  • Enthalpies of mixing
  • Surface tensions
  • And more


Key Features of COSMOthermX 21.0​

1. Thermodynamic Predictions Without Experimental Data

  • Based on quantum chemical calculations (usually via Turbomole or other DFT tools)
  • Uses COSMO surface charge densities to predict thermodynamic behavior
  • Eliminates the need for extensive lab work in many cases

2. Integrated GUI (Graphical User Interface)

  • User-friendly interface for setting up calculations and visualizing results
  • Supports batch processing for high-throughput screening of solvents or compounds

3. Database of Pre-Calculated COSMO Files

  • Comes with a database of pre-computed .cosmo files for thousands of molecules
  • Users can also generate their own using compatible quantum chemistry software

4. Support for Ionic Liquids

  • Specialized models for handling ionic liquids and charged species
  • Useful in green chemistry and solvent design applications

5. Integration with Process Simulators

  • Can be integrated with tools like Aspen Plus , gPROMS , or PRO/II for property prediction in process flowsheets

6. New Features in Version 21.0

  • Enhanced accuracy in solubility predictions
  • Improved modeling of hydrogen bonding and polar systems
  • Better performance and faster computation times
  • Expanded molecule database
  • Enhanced visualization tools for sigma profiles and interaction energies
