Hydrogen peroxide Innovation
Innovative processes such as the HP+ technologies we have developed for the direct synthesis of propylene oxide and propylene glycol make a significant contribution to environmental protection. The HPPO process produces propylene oxide on the basis of hydrogen peroxide, while the HPPG process produces propylene glycol. No harmful by-products are produced in the processes.
HPPO is the environmentally friendly direct synthesis of propylene oxide. The HPPO process uses hydrogen peroxide (H2O2) as an oxidant to oxidize propylene to propylene oxide (PO), with only water as a co-product and lower investment costs.
To meet the growing demand for propylene glycol, Evonik has developed the HYPROSYN® process together with Dow. By adapting existing production plants to HYPROSYN®, the intermediate propylene oxide is no longer needed and can already be used as a base material for PU products.
