Abstract:
The enantiomeric resolution of a series of N-arylamides was examined on amylose tris[(S)-1-phenylethylcarbamate] coated onto aminopropylated 7 microns silica with 500 A diameter pores and on naked silica 5 microns particle size with 500 A diameter pores. The enantiomeric resolution obtained for this series was excellent on both columns. The enantioselectivity of cellulose and amylose tris(3,5-dimethylphenylcarbamate) coated onto APS-Hypersil (120 A pore size, 5 microns particle size) was also investigated for this series of compounds.
