ABSTRACT:
Hydrolysis of olefin oxides to their corresponding glycols was catalyzed by a steam stable zeolite, in its acid form, characterized by a constraint index within the range of about 1 to 12. Conversions of olefin oxide, in the presence of water, proceeded with minimal catalyst degradation. The acidity of the zeolite enabled the use of milder conditions than generally applied for this hydrolysis with no loss of desired selectivity. In addition, the described procedure offered the advantages typically associated with a heterogeneous catalyst (e.g., ease of separation, use of fixed bed reactor, etc.).
