    摘要: The present invention relates to a process of separating chiral isomers of chroman compounds, particularly tocopherols and tocotrienols as well as the esters and intermediates thereof. It has been found that this process allows a separation of the desired isomer with a higher yield and enables the use of the non-desired isomers in a very efficient way. Said process is particularly useful when implemented in an industrial process. Furthermore, it has been found that this process allows using isomer mixtures as they result from traditional industrial synthesis.
