| 摘要 |
<p>The invention concerns a method for separating from a mixture two optical isomers using a simulated mobile bed, consisting of an assembly of columns (C1,C2,C3,C4, C5,C6,C7,C8) divided into at least three successive zones (I, II, III). Said method is characterised in that the amount of charge injected is greater than that of the state of a predetermined reference state, and the discharge flow is greater than that of said predetermined reference state if it is required at least to preserve the purity of the less immobilised enantiomer, or the discharge flow is less than that of the reference state if it is required to preserve the purity of the more immobilised enantiomer.</p> |
