Ethyl n-propyl ketone

To obtain an accurate quantitative analysis of the composition of a mixture, a knowledge of the response of the detector to each component is required. If the detector response is not the same for each component, then the areas under the peaks clearly cannot be used as a direct measure of the proportion of the components in the mixture. The experiment described illustrates the use of an internal normalisation method for the quantitative analysis of a mixture of the following three components ethyl acetate (ethanoate), octane, and ethyl n-propyl ketone (hexan-3-one).

Attempts to trap other di-alkyl ketyl radicals from methyl-ethyl, di-ethyl, di-n-propyl and di-isopropyl ketones were unsuccessful. The observed spectrum was not that expected from the ketyl radical but in each case it could be identified as that of a radical formed by a hydrogen abstraction from the parent ketone. The structurally similar radicals, CH3—CH—CO—CHg and CH3—CH—CO—CHa—CHg, were formed from methyl-ethyl and di-ethyl ketone respectively and the radical (0113)2—C—CO—CH—(0113)2 was formed by abstraction of the tertiary hydrogen from di-isopropyl ketone. The reaction of di-n-propyl ketone was somewhat unexpected as the spectrum obtained was typical of that for an allyl radical rather than an alkyl radical. It is possible that the allyl radical was formed by abstraction of a hydrogen adjacent to the carboxyl group in a parent molecule followed by an intramolecular rearrangement. Thus...
