n‐fatty acids: Comparison of published densities and molar volumes

Because some published n ‐fatty acid densities and molar volumes disagree significantly with others, an attempt was made, based primarily on the principle of homology, to distinguish between reasonably accurate and inaccurate data. Literature densities compatible with each other and with requirements of homology (including limiting densities) were identified. These densities, considered to be at least reasonably accurate, were used as standards and compared with other published densities. Most published n ‐fatty acid densities, judged by these criteria, appear to be reasonably accurate.
