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 10 percent of its original value. The low acidity catalysts produced in this way may be used for isomerizing alkyl di-substituted aromatic compounds, especially xylenes, to products containing higher proportions of the para-isomers.

Abstract translation: 通过在高于700℃，优选725℃至800℃的温度下在基本上无水的气氛中煅烧来降低沸石催化剂的酸度，以将α值降低到其原始值的10％以下。 以这种方式生产的低酸性催化剂可用于将烷基二取代的芳族化合物，特别是二甲苯异构化成含有较高比例对位异构体的产物。

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.).
