    摘要: A high-purity organic phosphine is obtained by washing organic phosphine or an organic solvent solution thereof with water, an alkaline aqueous solution or an acidic aqueous solution, whereby impurities, particularly, silicon compounds, 2-methoxy ethanol, and organic halides, contained in organic phosphine can be removed, so that such high-purity organic phosphine may be used as a raw material for high-performance compound semiconductor thin film with Groups III and V elements of the Periodic Table.
