Sodium tetrapropylammonium aluminum

Titanium(IV) isopropoxide, an aqueous solution of sodium hydroxide, a solution of 25 weight % tetramethylammonium hydroxide in methanol, aluminum nitrate nonahydrate and tetrapropylammonium bromide were used in the preparation of sodium CT. These chemicals were mixed to produce a white slurry. The slurry was loaded into a closed reactor and heated in an oven set at a temperature in the range of 423-473 K. The crystallization time was varied between twelve hours to two days. The synthesis details were presented by Anthony and Dosch [2]. Sodium CT was acidified by ion exchanging with an aqueous solution of HCl at pH of 2.0 for several times to remove Na+.
