On summarizing the previous results about S. W. L, the total sum of the analytical value of every components is low than 80% of all the solid, and as to the residual part ca. 20% nothing has bean known.
Various experiments were conducted on this part of unknown substances, by technique of ion exchange resin, conductometric titration, paper-chromatography and the other methods.
Next facts were surely assumed.
Certain high-and low molecular acids are concerned to this.
And further the high molecular acids show much of strongly combined sulfonic acid groups and little loosely combined ones and none of weak acid groups, whereas low melecular acids show much of loosely combines sulfonic acid groups and little strongly combined ones, and show weak acid groups.
As the results of paper chromatography, especially, it is suggested that this low molecular acids consist of sugar sulfonic, aldonic and other undetermined carbonic acids.
