摘要：

A spectrophotometric method has been employed to measure the surface acidities of stoichiometric and nonstoichiometric B-P-O catalysts. Three phosphorus/boron ratios, 0. 7, 1. 0, 1. 3, and three pretreatment temperatures, 200, 375, and 600 degree C, were employed. The data obtained appear to be consistent with earlier measurements of surface acidity by the hammett indicator method and by infrared spectroscopy and with the results of studies of probe reactions.
