Abstract
THE unsaturated fatty acids expected to be present in Hevea latex are very probably oleic, linoleic and linolenic. Altman1, using a method as described by Hazura, succeeded in showing the presence of oleic and linoleic acid in this latex. According to this method the unsaturated fatty acids are oxidized by alkaline potassium permanganate solution, converting them, to the corresponding oxyacids. Altman could identify the dioxystearic acid (m.p. 131°) and sativic acid (m.p. 175°).
