An Experiment in Physical Chemistry: Polymorphism and Phase Stability in Acetaminophen (Paracetamol)
Myrick, Michael L.; Baranowski, Megan; Profeta, Luisa T. M.
Journal of Chemical Education, v87 n8 p842-844 Aug 2010
Differential scanning calorimetry analyses of two easily prepared polymorphs of acetaminophen (also known as paracetamol) are recorded. The density of the forms can be found in the literature. Rules for heats of transition, heats of fusion, and density, as well as methods for determining the solid-solid transition temperature between the forms, are used to determine whether the two forms are enantiotropic or monotropic and to determine which is the more stable form at room temperature and pressure. (Contains 1 figure.)
