1798-33-00 PATENT CHEMICAL PROCESS FOR OBTAINING HIGH PURIFICATION OF MONOALKYLARSINES AND DIALKYLARSINES AND PURIFIED MONO- AND DIALKYLARSINES ABSTRACT OF THE DISCLOSURE 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-containing, germanium-containing, zinc- containing and other metal-containing impurities are removed from the alkali metal alkylarsenide. Mono- and dialkylarsine is then regenerated by reaction of the alkali metal alkylarsenide with a proton donor.
