摘要：

Two sulfated zirconia samples have been synthesized using different preparation procedures. Textural and acid properties of these catalysts have been characterized and compared with commercial zeolite H beta by means of nitrogen low-temperature adsorption, temperature-programmed desorption of ammonia and microcalorimetry. The two sulfated zirconias proved to be appropriate catalysts for acylations of aromatic compounds containing electron donating substituents, e.g., for syntheses of several aromatic ketones.
