Abstract
Two main unknown components in the by-product of camphor hydration synthesi s were separated and identified by fine fractional distillation and spectro scopic analyses. The components with different ratios of unknown components A and B were collected by the further distillation. The combined spectral results of GC, MS, GC-MS and C-13 NMR of the collected samples revealed tha t A is exo-2,2,3-trimethylbicyclo[2,2,1]heptane, and B is endo-2,2,3-trimet hylbicyclo[2,2,1]heptane.
