Drewson, Ber., 1883, 16, p. 2207); by passing the vapour of allyl aniline over heated lead oxide; by the condensation of ortho-aminobenzaldehyde with acetaldehyde in the presence of aqueous.
This compound condenses in alkaline solution with compounds containing the grouping - CH 2 - CO - to form quinoline or its derivatives; thus, with acetaldehyde it forms quinoline, and with acetone, a-methyl quinoline.
Wurtz); by boiling a-chlorpropionic acid with caustic alkalis, or with silver oxide and water; by the reduction of pyruvic acid with sodium amalgam; or from acetaldehyde by the cyanhydrin reaction (J.
It is also formed by the condensation of anthranilic acid with acetaldehyde (S.
The higher aldehydes of the series resemble acetaldehyde in their general behaviour.
Oxidation of ethyl alcohol gives acetaldehyde and acetic acid.
Grignard (Comptes Rendus, 1900 et seq.) showed that aldehydes combine with magnesium alkyl iodides (in absolute ether solution) to form addition products, which are decomposed by water with the formation of secondary alcohols, thus from acetaldehyde and magnesium methyl iodide, isopropyl alcohol is obtained.
Potash fusion converts it into acetic acid; nitric acid oxidizes it to acetic and oxalic acids; chromic acid mixture to acetaldehyde and acetic acid, and potassium permanganate to a0-dioxybutyric acid.
