  • Patent number: 6362352
    Abstract: Sulfur heteroatom substitution at the C4 position of 18F-labeled fatty acids yields a tracer that is retained in proportion to the beta-oxidation rates in mammalian tissue, particularly hypoxic myocardium. Most preferably, the invention is embodied in an [18F]fluoro-4-thia-fatty acid having a chain length of between 8 to 20 carbon atoms. The 18F-labeled 4-thia fatty acids of this invention find particular utility the radiolabelling of tissue sites (e.g., myocardium) for purposes of positron emission tomography.

  • Patent number: 6362353
    Abstract: Fatty acid sorbitan esters by direct reaction of sorbitol with fatty acid using a phosphorus oxyacid, including reducing phosphorus oxyacid particulary phosphouous acid, catalyst system and an alkali or alkali earth metal base, particulaly oxide, hydroxide or carbonate, in an axid:base molar ratio of 0.9:1 to 1.7:1, at a calalust concentration of 1.5 to 30%, particularly 3 to 12%, by weight of sorbitol can have lower color than products of prior commercial bulk processes even without the use of activated carbon and product bleaching typically used previously. The esters can be further reacted with alkylene oxide to make desivatives, particularly polysorbates. The esters and polyalkyleneoxy detivatives are useful surfactants in various application. Products of low color made without using activated carbon or bleaching are attractive for personal care applications.

  • Patent number: 6344573
    Abstract: A process for the extraction and concentration of unsaponifiable substances, containing liposoluble vitamins and provitamins, growth factors and animal and vegetable hormones, from residues of the industrialization of animal or vegetable products. This process does not require the use of solvents. Its main goal is to obtain the separation of these “valuable products”, by means of distillation/evaporation at high vacuum, and the production of fatty acids and other high quality organic acids, once the recovery of the unsaponifiable fraction of residues from the industrialization of animal or vegetable products, is of great commercial interest.
