A method for the production of polyetherols using aluminum phosphonate catalysts
is disclosed. Reaction products of the process include various polyetherols including
very low unsaturation polyether polyols. The aluminum phosphonate catalyst preferably
has a general structure of RPO-(OAlRR";)2, wherein O represents
oxygen, P represents pentavalent phosphorous, Al represents aluminum, R comprises
a hydrogen, an alkyl group, or an aryl group, and R and R"; independently
comprise a halide, an alkyl group, an alkoxy group, an aryl group, or an aryloxy
group. Polyols produced according to the disclosed procedure have properties very
similar to or more beneficial than those produced utilizing the typical base catalysts.
