Dippr 801 |top| May 2026

But what exactly is DIPPR 801, where does it come from, and why do engineers trust it above all others?

DIPPR 801 is not flashy, but it is foundational. Behind every reliable chemical process simulation, there is a quiet reliance on this database. It represents what engineers do best: take messy, scattered experimental data and turn it into trustworthy, practical tools.

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. dippr 801

DIPPR 801: The Gold Standard Database for Physical Properties in Process Engineering

For decades, engineers have sought a single, reliable source for these critical properties. Enter —the industry’s gold standard database for thermophysical properties of pure compounds. If you simulate a distillation column, size a pump, or design a reactor, chances are high that your work relies on DIPPR data. But what exactly is DIPPR 801, where does

With DIPPR 801, you have equations fitted to the best experimental data available—often with uncertainties under 1-2%. The result is a design that works the first time, saving millions in rework and downtime.

Whether you are a student learning Aspen Plus, a process engineer checking a pump curve, or a researcher developing a new solvent, DIPPR 801 is the benchmark you can trust. It represents what engineers do best: take messy,

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.
