Abstract
The reaction of Al(H2O)63+ and [Al13O4(OH)24(H2O)12]7 with alpha-Ti(PO 4)2 . 2RNH3-H2O (R = C3H7, C4H9) has been investigated. The processes can be considered as RNH3+/Al(H2O)63+ or RNH3+/[Al13O4(OH)24(H2O)12]7 ion exchange. With Al(H2O)63+, saturation is reached and an alpha-Ti[ Al(H2O)6]2/3(PO4)2 . nH2O phase is formed. With [Al13O4(OH)24(H2O)12]7 +, materials were obtained with the highest aluminum content, having t he formula alpha-Ti[Al13O4(OH)24(H2O)12]x(PO4)2 . (2 - 7x)RNH3 . nH2O (x = 0.20, R = C3H7; x = 0.14, R = C4H9). These compounds maintain ion -exchange properties. The porosity of the materials obtained is discus sed.
