Alumina aluminum phosphates in various aluminum to phosphor ratios were synthesized. The pore size can be easily controlled. The surface is weakly acidic. The number of acid sites per unit surface area shows a maximum at Al/P=1.9. The dehydration activity of tert‐butanol correlates with the total acid amount, whereas the dehydration activity of isopropanol is related to both the mumber of acidic and basic sites.
