  • Production of d-alpha-tocopherol from natural plant sources
    Patent number: 4977282
    Abstract: Quantities of natural tocopherol can be aminoalkylated to selectively introduce functional groups onto the 5 and 7 positions of the non-alpha-tocopherol homologues. Natural d-alpha-tocopherol can then be separated from the aminoalkylated non-alpha-tocopherols as salts. After separation the adducts can then be reduced by hydrogenolysis, thereby upgrading vitamin E activity by making d-alpha-tocopherol out of the intermediate tocopherol adducts. Salts of these adducts can be crystallized by contacting the adducts with phosphoric acid. Salts will form upon acetic acid addition, and the delta-tocopherol adduct acetate can be isolated as a crystalline solid. The adducts can also be regenerated from the salts and transformed to alpha-tocopherol by reduction of the adduct.

  • Process for desludging phosphating baths and device for carrying out said process
    Patent number: 4968360
    Abstract: The development of sludge in phosphating baths is prevented by continuously diverting a partial volume of the baths into a separate device comprising three open chambers: an oxidation chamber where the solution is treated with an O.sub.2 -containing gas to oxidize the iron (II) of the solution of iron (III), which precipitates as phosphate; a conditioning chamber in which the iron (iii) phosphate precipitate formed in the oxidation chamber is agglomerated into a readily sedimented form; and a sedimentation chamber in which the sediment formed in the conditioning chamber is separated from the remaining liquid phosphating solution. This solution is then replenished with phosphate layer-forming components, and the replenished solution is subsequently recycled to the phosphating bath.
