This article investigates possible lubricity additive applications for a number of products separated from a C/sub 17/-C/sub 20/ fraction and still-bottoms in synthetic fatty acids (SFA) production. Each additive (MKNK, DKK, NKK and FKKO) was dissolved in a hydrotreated T-7 fuel, and lubricity properties were evaluated by the KIIGA-2 method. Finds that the branched-chain monocarboxylic and unsaturated acids recovered from the C/sub 17/-C/sub 20/ SFA fraction, and also the fraction of acids from the SFA still-bottoms, form rather strong chemisorbed films on metal surfaces, and fuel formations based on these materials have a high level of lubricity.
