Reaktionsschritte
83.5 g of 8-cyanooctanoic acid dissolved in 300 ml of dimethyl ether ethylene glycol are heated to 130° C. for 4 hours in the presence of 50g of 40% caustic soda. After cooling, the reaction mixture is diluted with water, then acidified to pH 5 with diluted sulfuric acid, and then the precipitated solid is filtered. After drying, 92 g of azelaic acid with a m.p. of 107° C. are obtained.
