Fig. 2.--Infrared spectra: curve 1, component I; curve 2, n-butylbenzene; curve 3, component 11; curve 4, l-ethylcyclooctene; curve 5, component 111; and curve 6, ethylcyclo6ctane. red absorption spectra, but also IV was found to be identical with Component 11. Since both Components I1 and I11 could have been produced from the same material on hydrogenation and the butylbenzene was probably produced from a single material, it ...
