Abstract
ANACARDIC acid, the major component of the liquid extracted by solvent from cashew-nut shells1, was regarded as a homogeneous chemical entity containing in its aliphatic side-chain of fifteen carbon atoms two double bonds until recently, when it was shown by Izzo and Dawson2 to be in fact a mixture of olefinic components of which they identified the mono-olefin in the form of a crystalline glycol of the methylated anacardic acid. The present communication reports the complete separation of the mixture into its several components and the determination of their olefinic structure.
