Our C5 Technology

At Pyran, we have harnessed the power of nature to produce 1,5-PDO, a green 5-carbon alternate to the petroleum based 4- and 6-carbon diols that the world is currently limited by.

Unlocks the Potential for:

1. Enhancing Performance

  • Increased polymer heat, water, oil, and weather resistance

  • Increased thermal transition temperature and crystallization half time

  • Increased liquid phase processibility

enhanced performance

2. Easily Replacing Petroleum-Based Chemicals

Our customers have verified Pyran’s 1,5-PDO can:

  • Directly substitute for petroleum-based 1,5-PDO

  • Be considered a suitable replacement for 1,6-hexanediol in resins used for coatings

  • Demonstrate slightly better viscosity reduction that HDDA in certain applications

3. Improving Your Environmental Footprint

Our proprietary process reduces over 95% of greenhouse gas emissions compared to petroleum and carbon-neutral process with no harmful byproducts.

4. Reducing Cost

Pyran’s propriety process has high yield and is the only process in the world that makes ‘on-purpose’ 1,5-PDO allowing for lower costs.

Pyran’s C5 Technology Platform

pentanediol synthesis pathway

Pyran’s proprietary process represents the only cost-effective gateway to 5-carbon products. Our catalytic pathway to make 1,5-PDO from agricultural products is just the beginning.

We are exploring how our technology platform should expand and enable other critical chemical product supply chains and applications.
