Nonylenic acid

This is the simplest case of the reaction but it has been mostly used in the synthesis of higher members of the unsaturated acid series, e.g., the nine carbon acid, nonylenic acid, which is prepared from the seven carbon aldehyde known as oenanthylic aldehyde, or oenanthol, obtained from castor oil. Even more important than its application in the synthesis of higher acids of the ethylene series is the use of the reaction in the synthesis of aromatic unsaturated cLcids derived from benzene and containing an unsaturated side chain (see cinnamic acid. Part II). The reaction is known as the Perkin Synthesis or as the Perkin-Fittig Synthesis from the men who suggested and explained it. 

NONYLENE or 1-NONYLENE (27214-95-8) Forms explosive mixture with air (flash point 78°F/26°C). Violent reaction with strong oxidizers, strong acids, bromine, perchlorates, perchromates, pyridinium perchlorate, peroxyacetic acid, peroxybenzoic acid. Attacks some plastics, rubber, and coatings. Flow or agitation of substance may generate electrostatic charges due to low conductivity.
