    The CHETAH (Chemical Thermodynamic and Energy Release) program is a unique tool for predicting both thermochemical properties and certain reactive chemicals hazards associated with pure chemical, a mixture of chemicals, or a chemical reaction. This is accomplished through knowledge of only the molecular structure(s) of the components involved by an implementation of Benson's method of group additivity. CHETAH is useful for classifying materials for their ability to decompose with violence, for estimating heats of reaction or combustion, and for predicting lower flammable limits.

    This most updated version of CHETAH comes with the following enhanced features:

    • Version 10.0 has a new interface to improve ease of use.
    • Database for Ideal Gas Benson groups is expanded. This database now contains 1060 groups and is the largest Benson group database known to exist. 148 groups were added since version 9.0 of CHETAH.
    • Updated thermodynamic values provided for 20 Benson groups based on latest best values in the literature.
    • Entropy values were predicted and added to the database for many ideal gas Benson groups that were missing such values.
    • Various property databases reviewed for consistency and accuracy.
    • Mixture flammability calculations were improved in accuracy to reflect latest technology.
    • Program now uses the Microsoft Access Database for database management and to manage the user interface. The calculation details are now accomplished in the VBA structure of Access and in C language. This change in programming language for CHETAH makes the program more compatible and seamless with the current versions of the Microsoft Windows operating system.
    • Output reports have been improved for clarity of presentation. It is now possible to generate pdf format reports direct from the interface.
    • The program now maintains a clear record of use with details of past sessions. Past sessions can easily be modified and recalculated.
    • It is now much easier to establish and maintain a user database of proprietary data to enhance the usefulness of CHETAH. The user database is portable to future versions or service packs.DS51
