摘要:
A polyether polyol is formed by a method utilizing an aluminum phosphate catalyst. The method includes providing an alkylene oxide, providing an initiator molecule having at least one alkylene oxide reactive hydrogen, and reacting the alkylene oxide with the initiator molecule in the presence of the aluminum phosphate catalyst or a residue of the aluminum phosphate catalyst. The aluminum phosphate catalyst may have the general structure of P(O)(OAlR′R″)3 wherein: O represents oxygen; P represents pentavalent phosphorous; Al represents aluminum; and R′ and R″ independently comprise a halide, an alkyl group, a haloalkyl group, an alkoxy group, an aryl group, an aryloxy group, or a carboxy group.
