The melting points of binary mixtures of oleic,linoleic, and linolenic acids

Summary 1. The melting points of binary mixtures of oleic, linoleic, and linolenic acids have been reported. 2. The oleic-linoleic acid system has eutectics for the α and β forms of oleic acid of 75.2 and 76.3 mole per cent linoleic acid, at −10.0° and −9.8°, respectively. 3. Linoleic and linolenic acid mixtures show only melting points intermediate between the pure acids. 4. The oleic-linolenic acid system has eutectics for the α and β forms of oleic acid of 82.7 and 85.5 mole per cent linolenic acid, at −15.7° and −15.1°, respectively.
