 The paper presents the application of metal-assisted and microwave-accelerated evaporative crystallization, MAMAEC, technique for rapid and selective crystallization of acetaminophen, with subsequent characterization by optical microscopy, powder x-ray diffraction, PXRD, and Raman spectroscopy. Acetaminophen crystals were grown predominantly as Form 1 on blank glass slides at room temperature and Form 2, with 39% purity on SIFs using microwave energy.
