The synthetic fatty acids (SFA) cuts contain considerable amounts of branched-chain acids and higher unsaturated acids that can be used as raw materials in producing dimers and trimers for corrosion protection. This paper examines the use of a commercial C/sub 17/-C/sub 20/ SFA cut from a petroleum refinery as the starting material in preparing dimers and trimers of higher unsaturated carboxylic acids. It investigates the synthesized dimers, which are readily soluble in hydrocarbon fuels, as corrosion inhibitors in T-8V and T-7 jet fuels, which are produced by methods involving hydrogenation. The dimers of unsaturated acids prepared from the iso-MCUA fraction give good corrosion protection of carbon steel and are essentially equal to the Santolene C in corrosion protection.
