More Information
Summary:A process for the production of an olefin oxide polymerization catalyst comprising: admixing at least one alkaline earth metal, liquid ammonia, an alkylene oxide, which is optionally substituted by aromatic radicals, and an organic nitrile having at least one acidic hydrogen atom to prepare a slurry of modified alkaline earth hexammine in liquid ammonia; continuously transferring the slurry of modified alkaline earth hexammine in liquid ammonia into a stripper vessel and continuously evaporating ammonia, thereby accumulating the modified catalyst in the stripper vessel; and upon complete transfer of the slurry of modified alkaline earth hexammine into the stripper vessel, aging the modified catalyst to obtain the final olefin oxide polymerization catalyst, and a catalyst obtainable by this process.
