I carried out an experiment and it goes like this:
2-bromoethanol + dihydropyran (DHP) ---> 2-(2-bromoethoxy)oxane
Acidic ion exchange resin was added alongside as a source of H+ ions (catalyst).
If, instead of using acidic ion exchange resin, a conventional acid such as p-toluenesulfonic acid was used as a catalyst. How can it be removed from the product?
I thought of using a weak base, but would there be any side products formed?
