    摘要: The process for preparing mevalonolactone compounds is carried out by means of batch system chromatography or a simulated moving bed chromatographic process using columns filled with an optical resolution filler comprising a polysaccharide derivative. The simulated moving bed chromatographic process comprises forming a circulation flow circuit comprising a plurality of columns endlessly connected in series; enforcing a fluid to flow through the circuit in one direction; providing the column series alternately with an inlet port through which the fluid is introduced into the column in the flow direction and with an outlet port, through which the fluid is taken out; intermittently shifting activation of the inlet port and the outlet port in the direction of the fluid flow; introducing a solution containing a racemic mevalonolactone compound and an eluent through an inlet port into the circuit; and simultaneously taking out a solution rich in the weakly adsorbable substance and a solution rich in the strongly adsorbable and desorbed substance through the outlet port.
