Abstract
This invention discloses processes and resulting products for the manufacture of metal heptonates from saccharides via a Kiliani-Fisher reaction and subsequent reaction with the desired metal. Manganese, iron, copper zinc and magnesium heptonates are each made by a slightly different process but the resulting metal chelates provide a soluble form of the metal for agricultural, industrial, environmental and construction uses. The amount of metal chelated is directly related to the percentage of fructose in the initial monosaccharide mixture. For cations with no color, the chelating agent can be decolorized with H.sub.2 O.sub.2 to give a lighter colored product providing the NH.sub.3 concentration is reduced below 0.35% prior to the decolorizing step. An equivalent strong oxidizing agent may be used instead of H.sub.2 O.sub.2.
