The UNIFAC Calculator simplifies complex chemical calculations, making it an essential tool for professionals in chemical engineering and related fields.

UNIFAC Calculator is an online tool developed by the UNIFAC Calculator team for chemical engineers, researchers and students involved in thermodynamics, separation processes and material science. It is designed to provide accurate predictions of non-electrolyte activities coefficients in liquid mixtures.

The calculator is based on the UNIFAC (UNIQUAC Functional-group Activity Coefficients) method, which is a popular and effective thermodynamic model for predicting the activity coefficients of liquid mixtures. It takes into account molecular interactions and the contribution of individual functional groups to the activity coefficients.

With UNIFAC Calculator, users can calculate activity coefficients for a wide range of non-electrolytes, including alkanes, alcohols, ketones, esters, ethers and more. The interface is user-friendly and allows for easy input of mixture composition. Results are displayed in a clear and concise format, with activity coefficients listed for each component in the mixture.

The tool is constantly being updated with new features and improvements based on user feedback and the latest research in the field of thermodynamics. Users can rest assured that they are using a reliable and up-to-date tool for their research or engineering calculations.

UNIFAC Calculator is a valuable resource for anyone working with liquid mixtures in the fields of chemical engineering, material science and related disciplines.
