This article is from International Journal of Molecular Sciences, volume 15.AbstractA chiral selector of cellulose-2,3-bis3,5-dimethylphenylcarbamate CBDMPC was synthesized by reacting 3,5-dimethylphenyl isocyanate with microcrystalline cellulose dissolved in an ionic liquid of 1-allyl-3-methyl-imidazolium chloride AMIMCl. The obtained chiral selector was effectively characterized by infrared spectroscopy, elemental analysis and 1H NMR. The selector was reacted with 3-aminopropylsilanized silica gel and the CBDMPC bonded chiral stationary phase CSP was obtained. Chromatographic evaluation of the prepared CSPs was conducted by high performance liquid chromatographic HPLC and baseline separation of three typical fungicides including hexaconazole, metalaxyl and myclobutanil was achieved using n-hexane-isopropanol as the mobile phase with a flow rate 1.0 mL-min. Experimental results also showed that AMIMCl could be recycled easily and reused in the preparation of CSPs as an effective reaction media.
