    Abstract: The present disclosure relates to reacting tin metal with crude TiCl4 containing arsenic to produce pure TiCl4, SnCl4, and an arsenic solid co-product. In some embodiments, the contaminant vanadium is removed as well. The reaction is preferably done in a continuous fashion in two stages for maximum through-put and utility at an elevated temperature. Distillation can be used to purify the TiCl4 produced and simultaneously yield a purified SnCl4 product. The synthesis of SnCl4 in this method utilizes waste chloride to save virgin chlorine which would otherwise be used.

    Abstract: This disclosure relates to a method for detecting at least one analyte in a tetrachloride sample comprising titanium, tin or silicon tetrachloride; comprising, (a) adding a mixture of water and acid, typically hydrochloric acid, to the sample under conditions effective for forming an aqueous solution of the sample; (b) introducing the aqueous solution of the sample into an inductively coupled mass spectrometer having a cell selected from the group of a reactive cell and a collision cell or both and producing an analyte ion comprising an interfering species; (c) contacting the analyte ion with a gas to produce a product which is substantially free from the interfering species; and (d) detecting and measuring at least one signal from the analyte in the solution. This disclosure further relates to a method for making an aqueous titanium, tin or silicon tetrachloride sample suitable for analysis in using inductively coupled plasma mass spectroscopy.

    Abstract: The present disclosure relates to reacting tin metal with crude TiCl4 containing arsenic to produce pure TiCl4, SnCl4, and an arsenic solid co-product. In some embodiments, the contaminant vanadium is removed as well. In another embodiment, the vanadium is removed separately through a commercial process and the resulting arsenic containing commercial grade of purified TiCl4 is reacted with elemental tin, sulfur and ferric chloride to substantially reduce the arsenic. The reaction is preferably done in a continuous fashion in two stages for maximum through-put and utility at an elevated temperature. Distillation can be used to purify the TiCl4 produced and simultaneously yield a purified SnCl4 product. The synthesis of SnCl4 in this method utilizes waste chloride to save virgin chlorine which would otherwise be used.
