Conclusions
-
1.
Nonsolvated titanium perchlorate was produced by the action of TiCl4 on anhydrous perchloric acid. Titanium perchlorate possesses an appreciable intrinsic vapor pressure and can be repeatedly sublimed at 70°C under vacuum. The properties of sublimed Ti(ClO4)4 differ from the properties of the starting material.
-
2.
It was established by the method of differential thermal analysis that Ti(ClO4)4. melts with partial decomposition at 85–95°C, and above 110°C under vacuum it decomposes to TiO2, O2, and oxides of chlorine. Nonsolvated titanyl perchlorate can be produced by prolonged exposure of Ti(C1O4)4 under vacuum at ∼70°C. The heating of Ti(ClO4)4 at atmospheric pressure ends in explosion at ∼130°C.
-
3.
The IR and Raman spectra of titanium perchlorate and titanyl perchlorate were taken, and it was shown that both compounds belong to the class of covalent perchlorates with bidentate perchlorato groups.
