DCM's volatility and ability to dissolve a wide range of organic compounds makes it a useful solvent for many chemical processes. In the food industry, it is used to decaffeinate coffee and tea as well as to prepare extracts of hops and other flavourings. Its volatility has led to its use as an aerosol spray propellant and as a blowing agent for polyurethane foams. WebAcid-base reactions can be used to strategically change the solubility of the compound into a certain solvent. This experiment will focus on the separation of a 1:1 mixture of 4-nitroaniline and naphthalene. Once the mixture is dissolved into the organic solvent dichloromethane, hydrochloric acid is added for the protonation of 4-nitroaniline.
