摘要： The present disclosure relates to reacting tin metal with crude TiCl 4 containing arsenic to produce pure TiCl 4 , SnCl 4 , 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 TiCl 4 produced and simultaneously yield a purified SnCl 4 product. The synthesis of SnCl 4 in this method utilizes waste chloride to save virgin chlorine which would otherwise be used.
摘要翻译：本公开涉及使锡金属与含有砷的粗TiCl 4反应以产生纯TiCl 4，SnCl 4和砷固体共产物。在一些实施方案中，还除去污染物钒。反应优选以两个阶段的连续方式进行，以实现最大的通过和在高温下的应用。蒸馏可用于纯化所生产的TiCl4并同时产生纯化的SnCl4产物。该方法中SnCl4的合成利用废氯化合物来保存原来的氯，否则将使用氯。

摘要： The present disclosure relates to reacting tin metal with crude TiCl 4 containing arsenic to produce pure TiCl 4 , SnC 4 , 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 TiCl 4 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 TiCl 4 produced and simultaneously yield a purified SnC 4 product. The synthesis of SnC 4 in this method utilizes waste chloride to save virgin chlorine which would otherwise be used.
摘要翻译：本公开涉及使锡金属与含有砷的粗TiCl 4反应以产生纯TiCl 4，SnC 4和砷固体共产物。在一些实施方案中，还除去污染物钒。在另一个实施方案中，通过商业方法分开除去钒，并将得到的含有砷的商业级纯化的TiCl 4与元素锡，硫和氯化铁反应，以显着降低砷。反应优选以两个阶段的连续方式进行，以实现最大的通过和在高温下的应用。蒸馏可用于纯化所生产的TiCl4并同时产生纯化的SnC4产物。该方法中SnC4的合成利用废氯化合物来保存原来的氯，否则将使用氯。
