How could you separate lauric acid from &-naphthol?
What methods can be employed to effectively separate lauric acid from α-naphthol? Specifically, I am interested in the techniques that can achieve this separation while maintaining the integrity of both compounds. Any insights into the mechanisms involved or recommendations for specific procedures would be greatly appreciated.

The melting point for lauric acid is about 45 degrees while it is 121 degrees for naphthol. So, in a mixture repeated cycles of slow warming and cooling should separate out lauric acid from naphthol. You can improve the efficiency by adding a dash of slightly acidic 70% isopropyl alcohol. This will deprotonate the lauric acid while maintaining the proton on naphthol during this process to enhance separation and purification of the two compounds. You could also flat-out distill the two products by maintaining the temperature of the solution at the boiling point of lauric acid to separate it from naphthol. This might also be a good polishing method.
45 degrees...........what? Can't believe they give bachelors degrees to people who don't even use units these days
