Abstract: The relationship between the catalytic activity of mixed butenes oligomerization over solid phosphoric catalysts and polycondensate of phosphoric acid,the crystalline forms of silicium phosphate in the catalyst have been studied.It was suggested that high activity component of solid phosphoric acid catalyst should be a mixture of pyro and ortho-phosphoric acid and crystalline"C"form of silicium phosphate.

Key words: Solid phosphoric acid catalysts, Oligomerization, Acid catalysis
