Dicarboxylic fatty acids
WebThrough microbial ω-oxidation of fatty acids with Candida tropicalis, long-chain dicarboxylic acids can be obtained. 42 Further microorganism engineering opens up the possibility to produce long-chain hydroxyacids. 43 The catalytic carbonylation of fatty acids like oleic acid or erucic acid can also lead to C19-dicarboxylic acid or C23 ... Dimer acids, or dimerized fatty acids, are dicarboxylic acids prepared by dimerizing unsaturated fatty acids obtained from tall oil, usually on clay catalysts. The CAS number of the material is [61788-89-4]. Dimer acids are used primarily for synthesis of polyamide resins and polyamide hot melt adhesives. They are also used in alkyd resins, adhesives, surfactants, as fuel oil additives, lubricants, …
