摘要:
The separation of isomeric monoterpenes, camphene and fenchene by complexation with beta-cyclodextrin is presented. Both of the monoterpenes form complexes with P-cyclodextrin (as shown by both gas chromatography and H-1 NMR) with similar stability constants nevertheless it is possible to separate them by re-crystallization. The crystal structure of beta-cyclodextrin with fenchene was also studied by X-ray diffraction. (C) 2012 Elsevier Ltd. All rights reserved.
