Chemistry

A shelf containing several chemicals, Salicylic acid,4-(4-Hydroxyphenyl)butan-2-one (a.k.a. Raspberry Ketone) and4-methylaniline, fell and the vials shattered. The white powdersare hopelessly mixed in a dustpan. You are promised a raise if youcan devise a procedure that a less qualified chemist will follow toseparate the three compounds. You must describe what extractionsteps are to be taken at each point of the separation and how toisolate and purify each compound again as a solid. To ensure thatyou get the raise, you will also need to suggest how to determinethe purity of each recovered sample.

The three organic compounds to be separated are Salicylic acid 44Hydroxyphenylbutan2one aka Raspberry Ketone and 4methylaniline which are acidic neutral and basic compounds respectively Salicylic acid will form salt with a base NaOH and 4methylaniline with an acid HCl The water soluble ionic salts are insoluble in less polar organic solvents dichloromethane DCM 44Hydroxyphenylbutan2one would not react with either acid or base See Answer
