Imagine designing a heat exchanger for a new refrigerant. The heat transfer coefficient depends on liquid thermal conductivity and viscosity. Using a generic estimation method (like a group contribution model) might give errors of 10-20% in these properties. That error compounds into undersized or oversized equipment.

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

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. Imagine designing a heat exchanger for a new refrigerant

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. That error compounds into undersized or oversized equipment

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

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.
