“…Dicarboxylic acids and their derivatives have many industrial applications (1)(2)(3). Diesters and linear polyesters of straight-chain fatty acids are used as plasticizers for polyvinyl chloride (3)(4)(5). Esters of dicarboxylic acids, with a specific amount of branching, are used as lubricants and hydraulic fluids over a wide temperature range (3,6).…”

Liquid‐phase catalytic oxidation of oleic acid with hydrogen peroxide in the presence of various transition metal/metal oxide catalysts was studied in a batch autoclave reactor. Azelaic and pelargonic acids are the major reaction products. Tungsten and tantalum and their oxides in supported and unsupported forms were used as catalysts. Alumina pellets and Kieselguhr powder were used as supports for the catalysts. Tungsten, tantalum, molybdenum, zirconium, and niobium were also examined as catalysts. Tertiary butanol was used as solvent. Experimental results concluded that tungsten and tungstic oxide are more suitable catalysts in terms of their activity and selectivity. The rate of reaction observed in the case of supported catalysts appears to be comparable or superior to that of unsupported catalysts. In pure form, tungsten, tantalum, and molybdenum showed strong catalytic activity in the oxidation reaction; however, except for tantalum the other two were determined to be economically unfeasible. Zirconium and niobium showed very little catalytic activity. Based on the experimental observations, tungstic oxide supported on silica is the most suitable catalyst for the oxidation of oleic acid with 85% of the starting oleic acid converted to the oxidation products in 60 min of reaction with high selectivity for azelaic acid.

“…Adipic and sebacic acid esters are used mainly as components of modern engine oils and as compressor oils, hydraulic fl uids and white oils in the textile and food industry. Branched diesters have been applied as lubricants and hydraulic fl uids over a wide range of temperatures [92,93]. Although diesters have good lubricating properties, their thermal stability is surpassed by polyol esters.…”

“…Simple polymer additives, like plasticizers and softeners for PVC and varnishes, synthetic lubricants for a wide temperature range and very special high standard nylons and polyesters are the final products. Sebacic acid and undecanedioic acid can be used in the same way as azelaic acid as intermediates for plasticizers, synthetic ester lubricants, polyesters and polyamides (7). Quiana, a polyamid fiber of Dupont, is derived from dodecanedioc acid.…”
