Special offer for computer program for chemical thermodynamic and energy release evaluation

The CHETAH (Chemical Thermodynamic and Energy Release) program isASTM International’sunique 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 can be used for classifying materials for their ability to decompose with violence, for estimating heats of reaction or combustion, for prediction of chemical equilibrium, and for predicting lower flammable limits.

11.0版本的新功能是NASA Lewis化学平衡计算，它允许用户预测用户选择的反应物列表的平衡组成、压力和温度。CHETAH数据库中广泛的化学品数据库可以用作反应物。此外，利用Benson基团分子片段数据库，可以将数据库中甚至没有发表的文献中的化学物质作为反应物输入。

理想气体本森群数据库包含1165个基团。这是目前已知的最大的本森集团数据库。总共添加了66个新组。47组已更新或包括额外数据。根据文献中最新的最佳值，热力学值提供了20个本森组。数据库中包含了许多理想气体本森群的熵值。这也使吉布的自由能计算成为可能。

版本11.0使用Microsoft Access进行数据库管理和用户界面管理。计算细节采用Access的Visual Basic应用程序结构，用C语言完成。猎豹11被设计为与当前版本的微软Windows操作系统兼容和无缝连接。

Users can generate pdf format reports direct from the interface as well as Microsoft Word© documents. Past sessions can easily be modified and recalculated. Past sessions from CHETAH 10.0 can be moved to the new version, 11.0.

Four instructional videos are available on the ASTM website to assist in your purchasing decision based on the needs of your laboratory. Currently, ASTMoffer单用户10%折扣，多用户15%折扣。
