Abstract: The present invention relates, in general, to the purification of boron trichloride (BCl3). More particularly, the invention relates to a process for minimizing silicon tetrachloride (SiCl4) formation in BCl3 production and/or the removal of SiCl4 in BCl3 product stream by preventing/minimizing the silicon source in the reaction chambers. In addition, a hydride material may be used to convert any SiCl4 present to SiH4 which is easier to remove. Lastly freeze separation would replace fractional distillation to remove SiCl4 from BCl3 that has been partially purified to remove light boilers.

Abstract translation: 本发明一般涉及三氯化硼（BCl 3）的纯化。 更具体地说，本发明涉及通过防止/最小化反应室中的硅源来最小化BCl 3生产中四氯化硅（SiCl 4）形成和/或在BCl 3产物流中除去SiCl 4的方法。 此外，氢化物材料可用于将存在的任何SiCl 4转化为更容易除去的SiH 4。 最后，冷冻分离将取代分馏，以从已经部分纯化以除去轻质锅炉的BCl 3中除去SiCl4。
