Based upon your experiences, suggest what would be the result if we heated a mixture of dichloromethane (bp 39-40 Celcius) and nappthalene (C10H8 with mp 80-82 degrees celcius and bp 218) to 60 degrees celcius, collected distillate until no further meaterial distilled, and then cooled the flask back to room temperature. (This type of mixture might be obtained at the end of an extraction experiment starting with a mixture of benzoic acid, benzocaine and naphtalene) What would be in the distillate, and what would be in the distillation flask?
