  • Title: Organic-inorganic hybrid materials for efficient enantioseparation using cellulose 3,5-dimethylphenylcarbamate and tetraethyl orthosilicate.

    Journal: Chem Asian J; 2008 Sep 01; 3(8-9):1494-9. PubMed ID: 18506867.
    Abstract:
    The hybrid bead-type chiral packing material (CPM) for preparative enantioseparation has been prepared from the cellulose 3,5-dimethylphenylcarbamate containing a small number of 3-(triethoxysilyl)propyl groups in the presence of tetraethyl orthosilicate, by a sol-gel reaction in an aqueous surfactant solution. The obtained hybrid bead-type CPM was packed into a column and evaluated by high-performance liquid chromatography. When compared with the commercially available Chiralpak IB, which is prepared by the immobilization of cellulose 3,5-dimethylphenylcarbamate on silica gel, the hybrid bead-type CPM was shown to exhibit a similar chiral recognition and possess a higher loading capacity.
