Camphoronic acid

When distilled with phosphorus pentoxide, camphor yields cymene, and with iodine, carvacrol. Both of these bodies are para-derivatives of benzene. On oxidation with nitric acid camphor yields many acids, of which the chief are camphoric acid, CjgHjgO, camphanic acid, CjoHj O, and camphoronic acid, CgHj Og. The constitution of these acids has an important bearing on that of camphor. Many formulae have been suggested for camphor during the past few years, but that of Bredt is now universally accepted, and has received complete confirmation by Komppa s synthesis of camphoric acid. This synthesis confirms the formula for camphoric acid as—... [Pg.242]

Bredt found that camphoronic acid (see p. 868) is trimethylcarballylic acid (1893) and, mainly by a study of the oxidation products of camphor, arrived at the formula given. The structure of camphoronic acid was confirmed by its synthesis by W. H. Perkin junr. and J. F. Thorpe. ... [Pg.871]
