ABSTRACT:
A method is provided for highly pure mono- and dialkylarsines, particularly removing substantially all silicon-containing impurities. A mono- or dialkylarsine is reacted with either an alkali metal or an alkali metal hydrocarbyl, thereby producing an alkali metal alkylarsenide. Silicon, germanium, zinc and other metallic impurities are removed from the alkali alkylarsenide. Mono- and dialkylarsine is then regenerated by reaction of the alkali metal alkylarsenide with a proton donor.
