Abstract: | The nature of the catalytic activity of defective calcium hydroxyapatites was studied. The activ-ity of synthesized defective hydroxyapatites in vapor-phase dehydration of trimethylcarbinol, methylphenyl-carbinol, -hydroxyisobutyric acid, in decomposition of 4'4-dimethyl-1'3-dioxane into isoprene wasanalyzed. |
