Abstract
The heats of formation of TiCl4(l), TiCl3(s), and TiCl2(s) were determined by chlorinating Ti, TiCl3(s), and TiCl2(s), respectively, in a nickel‐bomb calorimeter to give TiCl4(l). The directly measured heat of chlorination at 25° of Ti is —190.0±0.4, of TiCl3(s) is 20.9±0.1, and of TiCl2(s) is 69.9±0.8 kcal/mole—1. Relative to a value for the heat of formation of TiCl4(l) of —190.0±0.4, the corresponding values for the heats of formation of TiCl3(s) and TiCl2(s) are —169.1±0.4 and —120.1±0.8 kcal/mole—1, respectively.Keywords
