I want to dry p-toluenesulfonic acid with Dean Stark apparatus. If you have some material or detailed procedure then kindly let me know.
You should be able to dissolve it in dry toluene and use your Dean-Stark to azeotrope off the water.
Book Purification of Laboratory Chemicals Seventh and Enlarged edition
Thanks a lot for your help.
You could use camphorsulfonic acid as an alternative.

Thanks for the feedback
