Separation and Identification of C8 Aldehydes. Use of Gas-Liquid Chromatography, Nuclear Magnetic Resonance, and Infrared Spectroscopy

Abstract: A method for the separation and identification of aldehyde isomers depends upon the separation of an isomer approximately 90% pure b y large volume gas-liquid partition chromatography. The separated aldehyde is examined by nuclear magnetic resonance to determine the number of a-hydrogens, CHa-, CHx-, and CHgroups and by infrared spectroscopy to establish the presence or absence of -(CH2)3-or -(CH2)n-groups, where R is equal to or greater than 4. Finally, the aldehyde is reduced to a hydrocarbon by the Wolff-Ki… Show more

“…The only structure which is consistent with the presence of these structural groups is that of 2-methyl-l-hexene. A similar treatment of the data for the peak 12 fraction leads to the structural group assignments shown in Table II. The only structure consistent with the presence of these structural groups is that of 2-ethyl-lpentene.…”

“…Gas-liquid chromatography (GLC) separated compounds which were then collected and identified through functional group analysis. Isomeric aldehydes were separated by this technique and the fractions collected (44)• The aldehydes underwent a Wolff-Kishner reduction to hydrocarbons and were compared with API standards to identify the isomers.…”
