The present invention relates to the field of separating chiral isomers from each other. Particularly, it relates to the field of separating of chiral isomers of chromane or chromene compounds, particularly tocopherols, 3,4-dehydro-tocopherols and tocotrienols, as well as the protected forms thereof. It has been found that the use of supercritical carbon dioxide as mobile phase combined with the very specific chiral phase as stationary phase leads to a very efficient separation of the individual chiral isomers. As the method is very efficient and fast combined with advantageous in view of ecology it is of big industrial interest.
本发明涉及从彼此分离手性异构体的领域。特别是涉及将手性异构体分离的领域,尤其是对苯二酚或色酮化合物的手性异构体,特别是生育酚、3,4-脱氢生育酚和生育三烯酚,以及它们的保护形式。发现使用超临界二氧化碳作为流动相,结合非常特定的手性相作为静相,可以非常高效地分离各个手性异构体。由于该方法非常高效且快速,并且在生态方面具有优势,因此具有很大的工业利益。
