1.The results thow that antibiotic activi-ties of iso-borneol and borneo.
2.The reactive mechanism and the main effective factors of borneol synthetic in one step
3.Results The linear range of borneol was 0.301 8￣2.012 μg. The average recovery of borneol was 96.3 % with RSD of 1.08%.
4.The formation of camphor from the catalytic dehydrogenate of isoborneol in gas phase was investigated and catalyst CDH has been selected.
5.PREPARATION OF ISOBORNYL ACETATE FROM CAMPHENE WITH D72 RESIN IN FIXED BED AS CATALYST
6.The fragrant compounds of cookie of chrysanthemum such as chrysanthenone, camphor, beta-elemene, boneol were the characteristic fragrance of chrysanthemum.
7.any of various hard resins from trees of the family Dipterocarpaceae and of the genus Agathis; especially the amboyna pine.
8.The method for synthetic borneol was Area-Normalization (CV<1%) for borneol and isoborneol, respectively, on column of 5% DEGS.
9.According to the characteristics and technological requirements of the substance obtained after dehydrogenating exo 2 camphanol made by hydration, 9 # catalyst is manufactured and better technological condition for post treatment is determined.
10.The results show that there is obvious difference in the relative contents of chemical constituents between domestic and Spanish essential oils, although their main constituents were all ??α??pinene,? 1,8?cineole, camphene, camphor, borneol and ?β??pinene.
