Yes. #NH_4Cl# is soluble in water, while napthalene is not. #NH_4Cl# is ionic, while napthalene is nonpolar organic. Like dissolves like, and so something organic AND nonpolar can dissolve napthalene fairly well.

Napthalene:

What you could do is inject an organic solvent of a different density than water (such as hexanes, #rho = "0.655 g/cm"^3#) into solution that can dissolve napthalene. Then, agitate the solution by shaking it (with the cap on), and the napthalene should be in the organic solvent on top while the #NH_4Cl# should be in the water after the solution settles.

It would look something like this:

Then you can extract the part of the solution you want. (Pay close attention to the meniscus that you may see.)
