    Abstract: Methods for obtaining Tamaritt and Tamaritt-Intermediate based materials are implemented through a secondary chemical reactor providing a second chemical reaction conducted with at least two reactants. The first reactant is Tamaritt and the second is an inorganic, or organic, or bio-molecular reagent, or their combination. Tamaritt is produced in a primary chemical reactor, modulating chemical reactions, preferably using a plasma device, and producing certain byproducts. A solid organic dye is dissolved in water producing a solution placed into the primary reactor, wherein the temperature and pressure are predeterminedly adjusted. The byproducts are injected into the solution, thereby commencing a first chemical reaction conducted until it finally results in obtaining Tamaritt. Tamaritt-Intermediate byproducts, being bond-altering catalyst-reagents, are obtained at a certain stage of the process.

  • Patent number: 4495211
    Abstract: A process for the decaffeination of green coffee beans by the extraction, process stage (a), of soaked green coffee beans with an equilibrium extract of coffee beans, from which extract caffeine has been removed, resulting in caffeine-deficient beans, which are recovered, and an equilibrium extract of the beans, which in a series of successive process stages (b), (c), (d) and (e), is contacted with an adsorbent circulating counter-currently through the same process steps, said adsorbent having a preferential adsorption capacity for caffeine. The equilibrium extract from stage (a) together with solution from stage (e) are contacted in stage (b) with adsorbent from stage (c) with adsorption of caffeine from the solution. The resulting solution is partly returned to stage (a), and partly, in stage (e), contacted with "clean" adsorbent from stage (d). The resulting "clean" solution is contacted, in stage (d) with adsorbent from stage (e) with desorption of caffeine from said adsorbent.

  • Patent number: 4481223
    Abstract: An aqueous coffee extract is decaffeinated with a treated activated carbon. The activated carbon is first contacted with an ethyl cellulose solution in order to adsorb the ethyl cellulose on the carbon. The ethyl cellulose-containing activated carbon is then dried and contacted with an aqueous coffee extract. The substantially decaffeinated extract is subsequently separated from the carbon.

  • Patent number: 4465699
    Abstract: A process for producing a decaffeinated vegetable material, such as coffee or tea in aqueous extract or solid form, for use in preparation of beverages, which comprises:(a) contacting a caffeine-containing composition with a liquid, water-immiscible fatty material which is capable of removing caffeine therefrom;(b) maintaining said vegetable material and said fatty material in contact for a time sufficient to transfer caffeine from said vegetable material to said fatty material; and(c) separating the decaffeinated vegetable material from the caffeine-laden fatty material.Other features of the invention are described in the specification.

  • Patent number: 4453007
    Abstract: Provided is a method of increasing the purity of amphoteric compound compositions. The method is: (a) providing an amount of a crude amphoteric compound composition, (b) using a portion of the crude composition to prepare in solution a cationic salt of the amphoteric compound, (c) using another portion of the crude composition to prepare in solution an anionic salt of the amphoteric compound, (d) mixing together the solutions wherein a precipitate is formed, and (e) collecting the precipitate which is an amphoteric compound composition of higher purity than the crude composition.

  • Patent number: 4443601
    Abstract: Caffeine adsorbed on caffeine adsorbents is recovered by contacting the carbon with a solvent, preferably an aqueous solution of ethylene carbonate or propylene carbonate. The caffeine adsorbent is contacted with the solvent for a period time sufficient to remove at least a portion of the caffeine adsorbed thereon and then separated from caffeine-containing solvent. The caffeine may be recovered from the solvent by precipitation.

  • Patent number: 4364964
    Abstract: A process for removal of caffeine from green coffee beans is disclosed by extraction with an aqueous liquid and preferential adsorption of caffein from the extract by means of a synthetic polymer resin of the type that is obtainable by polymerization or copolymerization of monomers containing aromatic ring systems and acid groups, and whereby the ratio of the total adsorption capacity for caffein to the total ion exchange capacity is larger than about 1 and smaller than about 25.
