I'm trying to develop a method to analyze 1,3,5 trioxane for assay. I have considered dissolving the trioxane in chloroform and analyzing by gc but I have a few concerns. My first concern is that there may be high boilers that don't elute on the method. My second concern is that the trioxane may break down to formaldehyde. Another idea I had was to dissolve the trioxane in water, add ammonium nitrate which will react with any free formaldehyde and form nitric acid which will in turn force the trioxane to formaldehyde which will again react with ammonium nitrate to form nitric acid. I will then titrate the acid with a base solution. Any ideas?
