“…The species represented as Ti A and Ti B have yet to be characterised conclusively; however we found no IR evidence for TiOCl 2 (as Ti A ), for which a strong absorption at ∼820 cm −1 could be expected. 14 We postulate that a Ti-OCl species is formed in (R2) (Ti A ), which is still reactive towards TPTP in (R3) where it might also act as a source of chlorination (discussed below).…”

First responders face extraordinary risks when dealing with organic peroxides such as TATP due to the extreme sensitivity of this class of explosives, and to a lack of a robust chemical means of safe and rapid neutralisation. The Lewis acids TiCl4 and SbCl3 have been found to demonstrate a novel degradation mechanism, with TiCl4 degrading a model cyclic peroxide in minutes when used in a two-fold excess, or ∼3 hours at half equivalence. The products cannot re-form peroxide compounds as is the case with acid degradation, suggesting the two mechanisms are fundamentally different. The Lewis acids mediate a rearrangement reaction in the cyclic peroxide backbone leading to relatively innocuous products through deactivation of oxidising O. Sub-stoichiometric TiCl4 reactions highlight a secondary reaction pathway that also leads to some oxidative chlorination products, possibly mediated by an unconfirmed titanium-oxychloride species. SbCl3 was found to exhibit similar reactivity to TiCl4, although at a slower rate. A mechanism is proposed, consistent with the observations for both stoichiometric and sub-stoichiometric quantities of TiCl4.

Determination of TiOCl2 in refined TiCl4 was significant for analysis of its impurities. TiOCl2 could be determined by infrared spectroscopy due to its infrared characteristic spectrum line. However, normal infrared absorption cell was not fit for the sample analysis, because TiCl4 easily reacted with moisture in the air and immediately was hydrolyzed to form highly corrosive hydrochloric acid smoke. The infrared absorption cell with the window film of ZnSe ( Ф10×1mm, wavenumbers: 7800cm-1~440cm-1) and the glass cell (optical path: 22mm, 12mm, 7mm and 4mm) was assembled and utilized in determination of the TiOCl2 in refined TiCl4 by standard addition method. The detection limit of TiOCl2 was 26.5mg•kg-1, the regression equation was Y=1.0118X, R2=0.9926; With standard addition method, the regression equation of TiOCl2 was Y=1.9400X, R2=0.9940,This infrared absorption device was safe, simple and convenient, easily removable and washable, and re-useable. This method could meet the requirement of determination of TiOCl2 in refined TiCl4.
