Abstract
CASHEW nut (Anacardium occidentale Linn.) shell liquid chiefly consists of anacardic acid, an ortho-carboxymeta-alkyl phenol. Earlier workers1–3 have shown that the unsaturated alkyl side-chain in the acid consists of 15 carbon atoms and that the acid is a mixture of saturated and mono-, di-, and tri-olefinic compounds, in proportions that give, on average, about two double bonds per molecule. Properties of the sodium salt of the whole anacardic acid have been reported earlier4–6. However, considerable interest remains in the examination of surface-activity unsaturation relationship in the anacardic acid series. The work recorded here is an extension of previous work5 on whole anacardic acid.
