 Weise vorgenommen, worauf zu den von dem Bleichwasser getrennten Fettsäuren Alkalilauge, Soda oder Bariumkarbonat bis zur neutralen Reaktion gegen   Methylorange zugesetzt   wird, um die in den Fettsäuren noch enthaltene Schwefelsäure zu neutralisieren. Gewünschtenfalls kann die Zugabe des Neutralisationsmittels vor der Abscheidung der bei der zweiten Bleichoperation entstehenden Bleichlauge erfolgen. Sobald    dieMischungneutral'ist, wird die Rührvorrichtung   abgestellt und die Mischung mindestens eine Stunde lang absetzen gelassen, so dass sich das Wasser möglichst vollkommen abscheidet. Je länger dieser Ahscheideprozess dauert, desto vollkommener ist die Trennung.

   Sodann wird das Wasser vom Boden des Behälters abgelassen und in den Behälter D geleitet, und die Fetts uren find nun fertig für den Gebrauch zur   HersteUung   von Seife, Kerzen oder zu anderen Zwecken.

 charge benutzt wird, können die Fettsäuren unmittelbar im Behälter C gebleicht werden. 



   Von Wichtigkeit ist es, dass während der Bleichoperation der über den Fettsäuren befindliche Raum stets mit Dampf erfüllt ist, um den Luftzutritt zu verhindern, welcher den Erfolg der Bleichung zum grössten Teile aufheben würde. Es wird daher, wenn die Dampfschlange 26 nicht in Wirksamkeit ist, Dampf in den Oberteil des Behälters durch Rohr 3 oder auch durch ein vom Dampfrohr 2 ausgehendes Zweigrohr bzw. wenn der Behälter C zur Bleichoperation verwendet wird, durch Rohr 30 eingelassen. 



     Genunschtenfalls   kann auch nach jeder Bleichoperation Schwefelsäure zugesetzt werden. um die Abscheidung zu beschleunigen. 



   Selbstverständlich kann auch irgend ein anderer geeigneter Apparat zur Durchführung der Bleichoperation verwendet werden.

 EMI2.1
 Manner, whereupon alkali, soda or barium carbonate is added to the fatty acids separated from the bleaching water until the reaction against methyl orange is neutral, in order to neutralize the sulfuric acid still contained in the fatty acids. If desired, the neutralizing agent can be added before the separation of the bleaching liquor formed in the second bleaching operation. As soon as the mixture is neutral, the stirrer is switched off and the mixture is left to settle for at least an hour so that the water separates out as completely as possible. The longer this separation process lasts, the more perfect the separation.

   The water is then drained from the bottom of the container and directed into container D, and the fatty acids are now ready for use in making soap, candles or for other purposes.
 EMI2.2
 batch is used, the fatty acids can be bleached directly in container C.



   It is important that during the bleaching operation the space above the fatty acids is always filled with steam in order to prevent the entry of air, which would for the most part negate the success of the bleaching process. Thus, when the steam coil 26 is not in operation, steam is admitted to the top of the container through pipe 3 or also through a branch pipe extending from the steam pipe 2 or, if the container C is used for the bleaching operation, through pipe 30.



     If desired, sulfuric acid can also be added after each bleaching operation. to speed up the deposition.



   Of course, any other suitable apparatus can be used to carry out the bleaching operation.
