Abstract: The acidity of a zeolite catalyst is reduced by calcination in an essentially water-free atmosphere at temperatures above 700.degree. C., preferably from 725.degree. to 800.degree. C., to reduce the alpha value to less than about 10 percent of its original value. The low acidity catalysts produced in this way may be used for conversions requiring low acidity, shape selective catalysis, including dewaxing. The calcined, low acidity catalysts exhibit improved dewaxing activity.

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.).
