LONDON (CNI)--German specialty chemicals company Degussa-Huls and compatriot engineering firm Krupp Uhde are developing a new process for the production of propylene oxide (PO) from hydrogen peroxide.
The companies announced on Thursday that they have agreed to co-operate on the development of the process, which produces PO through the catalytic oxidation of propylene with hydrogen peroxide (H2O2).
Degussa-Huls has developed an optimised catalyst and determined the most important parameters for the process, they said in a statement, and Krupp will provide its expertise in plant engineering and technology. "This will generate the basis for further process development regarding commercial-scale production and later commercialisation."
The companies said the new, low-cost process produces no co-products in the manufacturing process and opens up a new sales potential for Degussa-Huls' H2O2 output. Degussa-Huls, which plans to merge with SKW Trostberg later this year, claims to be the world's second largest producer of H2O2.
PO is currently manufactured primarily through the chlorohydrine process, which produces a chlorine-containing waste liquor, and the PO/styrene monomer (SM) process, which generates large quantities of SM as a co-product. It has an above-average growth rate, the companies said, and is used primarily in the production of polyurethane (PU) and polyester resin raw materials.
