Abstract

PURPOSE: An alkali and then kieselguhr are added to a fermentation broth containing long-chain dicarboxylic acids formed by fermentation and the mixture is filtered under pressure, then the dicarboxylic acids are precipitated from the filtrate, whereby long-chain dicarboxylic acids useful as a starting material of perfumes are obtained in high yield.
CONSTITUTION: An alkali such as sodium hydroxide is added to a fermentation broth containing long-chain dicarboxylic acids and by-products to adjust the pH to about 10W13, preferably 11W12, resulting in dissolving the dicarboxylic acids. Then, 2W8wt%, based on the fermentation broth, of kieselguhr with particle sizes of about 1W80μ is added to the mixture and they are filtered under a pressure of 6W8kg/m2. A mineral acid is added to the filtrate to adjust the pH to lower than 4 to precipitate the acids. Preferably the precipitate is heated to a temperature of higher than 50°C to help the growth of crystals. The resultant mixture is filtered under pressure with a filter press or the like and the cake is dried to give the objective dicarboxylic acids.
