Acid strength of solid superacids was determined by temperature programmed desorption using pyridine. An approximately linear relationship exists between the acid strengths of solid acids determined by the Hammett method and the termination temperature of pyridine desorption. The acid strength of colored superacids versus temperature relationships practically fell on the linear line.
