    I am looking for more ways to investigate the composition of my product in terms of percentage of Aspirin molecules in the reflux product.

    The only method I have so far, is titration.

    I have thought about the idea of colorimetry, but am not sure how I can get another chemical to react with the Aspirin product so I can do this...

    Any takers?

    No, i'm wrong! its alredy a solid, i think you have chosen a very difficult investigation though! Isnt asprin a solid because you cool the reflux product in ice then vacuum filter and you get a solid?

    Vacuum filtration, yes. I don't believe there is any ice involved, though.
