FRITZ WTEDEBMANN, 0F CHABLO ENBURG, GERMANY, ASSIGNOR TO THE FIRM OF VEREINIGTE GHEMISCHE BURG, GERMANY.
W RKE AGTIENGESELLSC HAFT, OF CHARLOTTEN- PROCESS FOR THE MANUFACTURE OF BLEACHED SOAP.
No Drawing.
To all whom it may concern: 4
Be it known that I, Fnrrz WIEDERMANN, residing at 16 Friederich Karlplatz, Chare lottenburg, Kingdom of Prussia, German Empire, have invented new and useful Improvements in Processes for the Manufacture of Bleached Soap, of which the following is a s ecification.
Hereto ore it has been'impossible to manufacture light colored soaps from dark or discolored oils, fattyacids, fats and resins. It was therefore necessary to subject the raw materials to a bleaching process before saponification. This presented the defect that special apparatuswere necessary and that a long' time was required for carrying the process into practice, thus rendering it considerably more costly. It is truethat attempts have been made to bleach soaps after their formation by adding hypochlorite to the soap. This, however, imparted an unpleasant smell to the soap, and thissmell was transmitted to the articles washed with it.
In the process forming the object of the gresent invention the bleaching is efiected uring the boiling of the soap, that is to say during the process of its manufacture. It has been found that the alkaline salts of er-' sulfuric acid, without presenting the de ects of chlorin bleaching, effect a bleaching during the saponificatlon process, so that the final product is light colored. In particular the process has proved to be advantageous for linseed oil, cotton seed oil',-neats foot oil, palm. oil and the low-graded olive-oil called sulfur oil. t
The process is carried into. practice b adding the alkaline salts of persulfuric acid: such or example'as persulfate of sodium, to
the soap dur' or after boiling, according to the color 0 the raw materlal and the color desired for the final product. Generally the quantity of the ersulfate used should amount to say o the oil or fat. A larger or a smaller proportion may, however, be used. The boiling operation is carried out in the usual manner.
By means of this process the great advantage is attained that losses such as would otherwise occur in bleaching oils and fats are avoided and that the products formed from the bleach during the bleaching operation, such for example as sulfate of sodium,
sulfate of potassium and the like substances do not impair the soap but onthe contrary are of advantage to it. The alkaline salts employed are soluble in water.
The resent process is particularly suited for set? soaps, which it has hitherto been diflieult to obtain in a clear. condition.
Example: 2000 kgs. of red palm oil are boiled with 1200 kgs; of soda lye at 40 Baum and the necessary water so as to form a thin jelly. Then 20 k of sodium persulfate are dissolved in 150 gs. of water and added to the jelly, the whole being mixed and boiled until the red color has changed into a whitish yellow. Thereupon the graining is effected as usual.
I claim:
The dprocess for the manufacture of bleache soa which consists in adding alkali salts of t e persulfuric acids to the components of the soap'after the beginnin of the saponification and before the end 0 the sa onlfication. I
n witness whereof I have hereunto signed my name, this 17th day of May 1907, in the presence of two subscribin wltnesses.
