摘　　要：The by products from the dehydration of exo 2 camphanol in the camphor manufacture by hydration process contains two unknown components: A in 14% and B in 15%. The sample mixture containing 90% A and B with different mass ratio(ca. 1∶1, 1∶2 and 1∶4) were collected by further fine fractional distillation with 60 plate number for spectroscopic characterization. The combined spectral results of GC, MS and 13 C NMR of the samples revealed that A is exo 2,2,3 trimethylbicyclo[2,2,1]heptane(exo isocamphane) and B is endo 2,2,3 trimethylbicyclo[2,2,1]heptane(endo isocomphane).The by products from the dehydration of exo 2 camphanol in the camphor manufacture by hydration process contains two unknown components: A in 14% and B in 15%.
