Procedure

adding to said solution of chromium(VI) source in aqueous propionic acid a nitrite source employing sufficient nitrite source selected from the group consisting of alkali metal and ammonium nitrites to effectively reduce chromium(VI) to chromium(III) allowing sufficient time at sufficient temperature to produce a clear green solution of stabilized chromium(III) propionate; and
