Titanitartrates and Allied Salts






Titanic hydroxide dissolves in a concentrated solution of tartaric acid, and alcohol precipitates from this solution the tartrate Ti(C4H4O6)2.4H2O; whilst solutions, of alkali hydrogen tartrates dissolve the same hydroxide and form gelatinous substances of the composition 2M2'O.2TiO2.3C4H4O5.xH2O. The basic tartrate Ti2O3(C4H4O6).7H2O has also been obtained. The titanitartrates, as well as many other salts of complex acids formed by the combination of feebly acidic oxides with organic hydroxy-acids, have been studied by Henderson, Orr, and Whitehead, who record the previous preparation of titanicitrates, TiO(C6H6O7M')2, titanitartrates, TiO(C4H4O6M')2 and TiO:C4H3O6M', and titanimucates, TiO:C6H7O8M', and have obtained the following salts in a pure, crystallised state:

Sodium titanitartrateTiO(C4H4O6Na)2.8H2O
Potassium titanitartrate2TiO(C4H4O6K)2.9H2O
Ammonium titanitartrate2TiO(C4H4O6NH4)2.7H2O
Barium titanitartrateTiO(C4H4O6)2Ba.5H2O
Potassium titanicitrateTiO(C6H6O7K)2.H2O
Potassium titanimucateTiO:C6H7O8K.3H2O


All these salts are prepared by dissolving titanic hydroxide in a solution of the corresponding metal hydrogen salt of the hydroxy- acid. They are thus analogous to tartar emetic; and the constitutions of the complex acids may thus be represented:

Titanitartaric acid:
Titanicitric acid:
Titanimucic acid:


Since these acids contain the radicle TiO', the prefix titanyl- is perhaps preferable to titani-. A peroxidised titanitartrate of the composition TiO2.C4H4O6.2C4H5O6K.9H2O has also been prepared.
