A process for preparing the ferric and acid complex in a vessel includes charging solvent, the chelant, the base, the iron oxide, and the reaction promoter into the vessel. The solvent, chelant, base, iron oxide, and reaction promoter are heated to a temperature of at least 170° F. for a period of at least about 3 hours to form the ferric and acid complex. Due to the use of the reaction promoter having the Fe3+ ion, the process for preparing the ferric and acid complex results in reduced degradation of the chelant during processing and, thus, a high quality ferric and acid complex.

    Abstract: A composition and method of preparing amino acid chelates and complexes free of interfering ions by blending an amino acid ligand, a calcium oxide and/or hydroxide, and a hydrated metal sulfate salt, placing the blend in a closed environment, heating the blend, and allowing the blend to react is disclosed and described. By heating at low to moderate temperatures in an enclosed environment, the waters of hydration of the metal salt are retained in the enclosed environment and serve to provide the moisture necessary to enable a bonding reaction to take place between the electron rich functional groups of the ligand and the metal ion of the hydrated metal sulfate salt. Additionally, calcium sulfate is formed which can be maintained in the final product.

  • Patent number: 6590115
    Abstract: Disclosed are substantially enantiomerically pure bis-phosphine compounds comprising a substantially enantiomerically pure chiral backbone linking two phosphine residues wherein one of the phosphine residues has three phosphorus-carbon bonds and the other phosphine residue has two phosphorus-carbon bonds and one phosphorus-nitrogen bond wherein the nitrogen is part of the chiral backbone. The compounds, which have exhibited surprising air stability, are useful as ligands for metal catalysts for asymmetric reactions and have demonstrated excellent results, in particular as rhodium complexes for asymmetric hydrogenation of enamide, itaconate, and &agr;-ketoester compounds. Also disclosed are novel processes for the preparation of the bis-phosphine compounds and novel intermediate compounds useful in the preparation of the bis-phosphine compounds.

  • Patent number: 6472548
    Abstract: The present invention provides a process for the preparation of a chelant or chelating agent complex of the formula L•B•M. L is an amino acid derivative including two optically active amino acids are linked via a (CH2)n group, wherein the (CH2)n group is attached to a nitrogen of each optically active amino acid, the optically active amino acid may be the same or different; and wherein n is an integer from 1 to 10; B is a base; and M is a metal. The process comprises the steps of (i) providing a reaction mixture comprising L and B and having a pH of less than 7.5; (ii) contacting the reaction mixture with M to provide a first complex mixture; and (iii) contacting the first complex mixture with a further amount of B to provide a second complex mixture. The second complex mixture can further be sequentially contacted with further amounts of M and further amounts of B. Alternatively, the second complex mixture can be heated.
