84.5 g of 8-cyanooctanoic acid are heated to 130° C. for 10 hours in the presence of 250 ml of concentrated sulfuric acid. After cooling, the reaction mixture is diluted with water and ice and the solid crystalline precipitate is filtered. After drying, one obtains 90 g of azelaic acid with a m.p. of 107° C.
