ABSTRACT:
Impure methanol may be treated to remove iron pentacarbonyl impurities by adding a source of hypochlorite ions to the impure methanol whereby the iron of the iron pentacarbonyl will be oxidized to the ferrous or ferric state. The impure methanol is then subjected to distillation to remove iron compounds as heavy ends.
