WebInstrument Operation: Fisher-Johns Melting Point Apparatus Introduction: The preparation of phenacetin is a straightforward, two-step “one-pot” organic synthesis. It introduces the classic reaction of an amine with an anhydride to form an amide, and it also reinforces the principles of recrystallization and the determination of melting points. WebA melting-point apparatus is a scientific instrument used to determine the melting point of a substance. Some types of melting-point apparatuses include the Thiele tube, Fisher-Johns apparatus, Gallenkamp (Electronic) melting-point apparatus and automatic melting-point apparatus. What are the factors that affect the melting point?
