  • Purification of tocopherols
    Patent number: 4617406
    Abstract: Tocopherol homologues found in a tocopherol-containing feed material can be purified by forming a borate tocopherol ester and then distilling the material containing the esterified tocopherol to remove the materials boiling at temperatures lower than the esterified tocopherol. The borate tocopherol esters remaining after distillation are then reacted with a member selected from the group consisting of: Water, methanol, and ethanol to form tocopherol homologues from the borate tocopherol ester, and the boron by product from this reaction is removed. The tocopherol is then recovered by collecting it, distilling it or by any other convenient collection method.

  • Purification of tocopherols
    Patent number: 4550183
    Abstract: This invention relates to the purification and concentration of tocopherol compounds from an organic feed material containing these compounds. A sufficient amount of caustic methanol is used to contact a tocopherol-containing organic material whereby two phases are formed; one of which is tocopherol-enriched caustic methanol. The phases are separated and the caustic is neutralized. The tocopherol is then recovered from the tocopherol-enriched methanol. One way of recovery is by adding a sufficient amount of water, causing the tocopherol to form a separate phase, which can then be removed in this more purified, concentrated form. Alternatively, the tocopherol can be isolated by removal of the methanol by distillation after acidic neutralization, and then washing the tocopherol with water to remove the salt resulting from neutralization.
