| titleOfInvention | PROCESS FOR RECTIFICATION OF VITAMIN ACETATE E. |
| abstract | Process for the finishing of vitamin E acetate, characterized in that, in a first stage of purification, the product stream is fed to a rectification column (1), the products of low boiling point and the unspecified isomers of acetate being removed of vitamin E at the upper end (1a) of this column, withdrawing a stream containing the vitamin E acetate in purified form by lateral extraction (15) and / or by the bottom (1b) of column (1) and thus, the loss of useful product in the first stage of purification is less than 5%, based on the amount of VEA in the feed that is added to the stage of purification per unit of time and because, in a second stage of purification , the lateral extraction of vitamin E acetate and / or the extraction at the bottom of the first column is fed to a second rectification column and the vitamin E acetate is removed in a stream with a purity> 97% by weight o and a subsequent current with a purity> 92% by weight, and further characterized in that the lateral extraction or the extraction by the bottom of the first rectification column (1) is fed in the second purification stage to a second rectification column ( 19), and because vitamin E acetate is removed from the second column (19) as a lateral extraction with a purity> 97% by weight and as a mixture consisting of the superior extraction and the distillate of the extraction by the bottom with a purity> 92% by weight. |
