Dippr 801 |top| -

DIPPR stands for the , a membership consortium within the American Institute of Chemical Engineers (AIChE). The "801" refers to the specific project number that began in 1980: a sponsored effort to compile, evaluate, and recommend the most reliable thermophysical properties for industrially important chemicals.

The result is the , a critically evaluated collection of over 2,000 pure compounds, ranging from common solvents and hydrocarbons to specialty refrigerants and monomers. For each compound, the database provides temperature-dependent prediction equations for 36 distinct properties. dippr 801

In the world of chemical engineering and process design, accuracy is non-negotiable. A slight miscalculation in a fluid’s viscosity or heat capacity can lead to undersized pipes, failing heat exchangers, or even catastrophic safety incidents. DIPPR stands for the , a membership consortium
