Desired product is chlorohydroxypropyl ammoniumchloride which is made by reaction epichlorohydrin and trimethylamine hydrochloride. 1,3-DCP is undesired byproduct. And to remove is dificult because its boiling point is 174C. I tried some resins to remove but it didnt work.
Do you have access to a controlled vacuum? You could vacuum distill the DCP off with mild heating. Strange that ion exchange resins didn't work though. What were you using?
