The Influence of Substituents. The substituents at the groups indicated have a markedly smaller effect on z and t. This is evidence for the orientation of the molecules with their reacting atoms toward the catalyst (Fig. 13), as is required by the theory. The influence is particularly slight in the case of metals. For hydrocarbons (Nos. 1-3), amines (23-29), and alcohols Z — 1 and z3 = 0. From a crisscross examination of the data of Nos. 40-47, it can be seen that in the case of copper not only the values of z2 but also those of a2 are practically the same for ethyl, n-propyl, isopropyl alcohols, acet- and propionic aldehydes, and also acetone. This was explained by the author (66) in a treatment of the above-mentioned model from the standpoint of statistical mechanics. It was found that... 

Propyl Alcohol.—n-Propyl alcohol offers a considerably greater resistance to electrical oxidation than methyl or ethyl alcohol, according to experiments made by Elbs and Brunner.1 Propionic acid is formed as the principal product, with a current yield of over 90%, at bright (polished) and platinized platinum anodes, as well as at lead peroxide anodes when the alcohol is electrolyzed in sulphuric-acid solution. A little propionic aldehyde also occurs at lower current densities. The formation of carbon mon- and dioxides is likewise very insignificant. 

If butyric acid is electrolyzed with perchlorate, according to the procedure of Hofer and Moest,2 hexane is the preponderating product there are also obtained propyl alcohol and its oxidation product, propionic aldehyde ... 

Propaldehyde—Propionic aldehyde—CH3,GHa,COH—58—obtained by the general reaction from propylic alcohol, is a colorless liquid, resembling acetic aldehyde boils at 40° (120°.2 F.). 

Among these are aldehyde, acetone, propyl alcohol, butyl alcohol, and propionic aldehyde. 

Write equations for reactions by which propionic aldehyde, CaHs-CHO can be converted into (o) propionic acid, (6) propyl alcohol, (c) sec-butyl alcohol, and (d) diethyl ketone. 

While enologists have been interested in the odorous constituents of grapes and wines for many years, Hennig and Villforth (1942) and Hennig (1943, 1950-1951) seem to have made the first systematic studies on the subject. They extracted wine with pentane and after hydrolysis identified the alcohols and acids. They reported the following aldehydes, ketones, and related compounds (formaldehyde, acetaldehyde, propion-aldehyde, cinnamaldehyde, vanillin, acetone, methyl ketone, acetyl-methylcarbinol, and acetal—caproaldehyde and higher members of the series, benzaldehyde, and furfural were not positively identified but probably also occur) alcohols (methyl, ethyl, isopropyl, isobutyl, isoamyl, and a-terpineol—n-propyl, n-heptyl, and sec-nonyl (2-nonanol)...
