  • Process for the preparation of optically pure or enriched racemic tetralone
    Patent number: 6683220
    Abstract: A process for producing substantially optically pure sertraline utilizes chromatographic separation on a solid stationary chiral phase of spherical clay particles having an interlayer containing an optically pure metal-organic complex, and a liquid mobile phase preferably containing at least methyl acetate. The liquid mobile phase is preferably free of acetonitrile. The process is operable at temperatures above 40° C.
    Type: Grant
