METHOD FOR PURIFICATION OF DISILICON HEXACHLORIDE AND HIGH PURITY DISILICON HEXACHLORIDE |
摘要 |
<p>The objective of the present invention is to provide a method for obtaining a high purity disilicon hexachloride by removing a silanol with good efficiency from a disilicon hexachloride material containing the silanol as an impurity. The purification method for disilicon hexachloride of the presnt invention comprises a process for contacting a disilicon hexachloride material containing disilicon hexachloride and a silanol as an impurity with an adsorbent material such as activated carbon to remove the silanol. The method may further comprise a distillation process. The above processes are preferably performed in an atmosphere of an inert gas.</p> |
