    Abstract: Polyether polyols, derivatives and combinations thereof are converted to olefins under reductive or non-reductive dehydroxylation conditions, in the presence of a halogen-based catalyst. Derivatives include polyether polyols incorporated in polyurethanes. The process includes gas pressure from 1 psig (~6.89 KPa) to 2000 psig (~13.79 MPa), a temperature from 50 °C to 250 °C, a liquid reaction medium, and a molar ratio of the starting material to halogen atoms from 1:10 to 100:1.
