Abstract

Beschrieben wird ein Verfahren zur Herstellung von alpha-Tocopherol aus einem nicht-alpha-Tocopherole enthaltenden Rohmaterial, bei dem man die im Rohmaterial enthaltenen Tocopherole in Tocopherylborate umwandelt, das so behandelte Rohmaterial erhitzt, um niedriger als die Tocopherylborate siedende Bestandteile des Rohmaterials abzudestillieren, den Rückstand einer Methylierung unterzieht, um die nicht-alpha-Tocopherylreste in alpha-Tocopherylreste umzuwandeln, und die Tocopherylborate einer Solvolyse zu alpha-Tocopherol unterzieht und die borhaltigen Solvolyseprodukte entfernt.Disclosed is a process for producing alpha-tocopherol from a raw material containing non-alpha-tocopherols, in which the tocopherols contained in the raw material are converted into tocopheryl borates, the raw material thus treated is heated to distill off lower boiling components of the raw material than the tocopheryl borates Methylates the residue to convert the non-alpha-tocopheryl residues to alpha tocopheryl residues and subject the tocopheryl borates to alpha-tocopherol solvolysis and remove the boron-containing solvolysis products.
