Preparation of dibenzoyl-D-tartaric acid molecularly imprinted monolithic column and its chromatographic property

YANG Wei-jie,CHEN Xiao-qing,JIAO Fei-peng(School of Chemistry and Chemical Engineering,Central South University,Changsha 410083)  
Acrylamide was chosen as the functional monomer by a convenient method of UV spectrometry.The Dibenzoyl-D-tartaric acid(D-DBTA) monolithic molecularly imprinted polymer(MIP) has been prepared by in situ polymerization using D-DBTA as the template,acrylamide as the functional monomer,Ethylene dimethacrylate as the crosslinker,and lower polar solvents(toluene and dodecanol) as the porogenic solvents.With the optimization of chromatographic conditions,the enantioseparation of DBTA was achieved within 25 min on the obtained monolithic column with a satisfactory resolution factor Rs=1.25.Thermodynamic data of separation were calculated.The results showed that two different thermodynamic processes appeared within temperature investigated and both fitted Van't Hoff plot very well.Just at the transition temperature of the two thermodynamic processes,the maximum of separation factor α was obtained.
