Extraction From Bark Or Vegetable Material Patents (Class 560/69)
  • Patent number: 8575378
    Abstract: Methods of producing plant polyols from plant oils include reacting a plant oil with a designed reactant having one or more nucleophilic functional groups and one or more active hydrogen functional groups in the presence of an addition reaction catalyst in a single reaction step. The resultant polyols may be directly reacted with polyisocyanates to produce polyurethanes.

  • Patent number: 7145031
    Abstract: Process and a plant to extract and concentrate tannins from wood and from other solid natural products containing it characterized in that the solid products are subjected to an extraction (1) by percolation with water and/or steam and the thus obtained tannin solution is subjected to nanofiltration (5).

  • Patent number: 5578118
    Abstract: The addition of from about 0.1 to about 1 parts by weight of a natural polyphenolic-containing vegetable extract (NPVE) per 100 parts of bitumens (particularly asphalt), coal tar, or other high boiling tars containing mixtures of aliphatic and aromatic hydrocarbons modifies the characteristics of the treated product to enhance its performance as hot-melt adhesives, coatings, sealants, roof-coatings, and road-coatings as compared to the base bitumen. The NPVEs are naturally occurring, are extracted from plants and include quebracho, chestnut, wattle and sumac. By forming the ammonia salt of NPVE (ammonium/NPVE) and adding it to a base or NPVE-modified bitumen, the characteristics of increased adhesion and resistance to stripping is observed. Surprisingly, the addition of commercially available anti-stripping agents to an ammonium/NPVE-modified bitumen results in a modified-bitumen having a stripping resistance greater than either of the additives alone.

  • Patent number: 4755618
    Abstract: A process for recovering active gallotannin for reuse comprising the extracting of dried schoene sludge (about 5% moisture) with a mixture of about 88 vol. % acetone--12 vol. % water to solubilize the gallotannins. The solvent is evaporated off, the residue is treated with water to solublize the gallotannins. After filtration, the clarified water solution is extracted with ethyl acetate. Evaporation of ethyl acetate leaves purified gallotannin which can be redissolved in water and spray dried to produce reusable powder. A preliminary step of separating yeast from the gallotannin protein complex involves treating with 60% acetone/40% H.sub.2 O at room temperature before making the solution about 88:12 acetone:water.

  • Patent number: 4408065
    Abstract: An adsorptive separation process for separating methylparaben from a feed mixture comprising methylparaben and wintergreen oil, which process comprises contacting the feed mixture with an adsorbent comprising a type X or type Y zeolite, selectively adsorbing substantially all of the methylparaben to the substantial exclusion of the wintergreen oil and thereafter recovering high-purity methylparaben. A desorption step may be used to desorb the adsorbed methylparaben. The process is carried out preferably in the liquid phase.

  • Patent number: 4251668
    Abstract: A process for extracting components of wood which can be used in the production of alcoholic liquids and the resulting product. The extract imparts characteristics to the liquid similar to those obtained in the course of natural aging. The process involves a multi-stage extraction with aqueous solvents, the last stage being conducted under pressure.
