    • 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.
    • 通过利用磷酸铝催化剂的方法形成聚醚多元醇。 该方法包括提供烯化氧,提供具有至少一个烯化氧反应性氢的引发剂分子,并在磷酸铝催化剂或磷酸铝催化剂的残基存在下使烯化氧与引发剂分子反应。 磷酸铝催化剂可以具有P(O)(OAlR'R“)3'的一般结构,其中:O表示氧; P表示五价磷; Al代表铝; R'和R“独立地包括卤素,烷基,卤代烷基,烷氧基,芳基,芳氧基或羧基。
