Aqueous solution of p-toluenesulfonic acid
Thread Content
The company currently uses a large amount of centrifugation mother liquor containing p-toluenesulfonic acid. Currently, 65% aqueous solutions of p-toluenesulfonic acid are available on the market; additives need to be added to such solutions to prevent the crystallization of p-toluenesulfonic acid within them. Does anyone know what kind of additives can be used?

The remaining components are 10-30% sulfuric acid and 1-10% free acid, right?
Yes, the indicators are roughly like this. Does President Zhang have any better solutions?
