Abstract
In present work menthol, camphene and camphor enantiomers separation was performed on 1m packed column filled with solid support with 5-hydroxy-6-methyluracile supramolecular structure impregnated (1 and 10 mass. %). The main idea of such modifier application is to use the prochirality of some supramolecular structures to achieve enantiomers separation capability. The separation conditions are: oven temperature 70 and80 °Cfor columns with 10 and 1 modifier percent respectively; carrier gas nitrogen flow-rate 20 ml/min. Specific retention volumes and factors of selectivity were calculated. The stationary phase suggested shown selectivity to all enantiomers studied. Factor of selectivity was for menthols 1,74 (in the case of column with 10% HMU) and 3,11 (in the case of column with 1% HMU); 2.38 for camphenes and 1,74 for camphor, that appreciably exceeds selectivity of most commercial cyclodextrins columns. Stationary phase suggested may have applications to novel chiral columns for chromatography and for preparative aims.
