Book Description
The illicit synthesis of phenyl-2-propanone (P2P) in clandestine drug laboratories from phenylacetic acid and acetic anhydride in the presence of sodium acetate or pyridine, or from the dry distillation of phenylacetic acid and lead (II) acetate is examined. These two routes are investigated using capillary gas chromatography (GC) combined with vapor-phase Fourier transform infrared (FTIR) spectroscopy and electron impact mass spectrometry (EIMS) detection (GC-FTIR-EIMS), and using nuclear magnetic resonance (NMR) spectroscopy to identify 21 reaction by-products. The mechanisms of the two reactions producing P2P are presented, along with the mechanisms giving rise to these by-products. This investigation has identified 4 reaction-specific compounds which can be used to differentiate the two synthetic methods.

Book Description
The feature of polyimides and other heterocyclic polymers are now well-established and used for long term temperature durability in the range of 250 - 350'C. This book will review synthesis, mechanisms, ultimate properties, physico-chemical properties, processing and applications of such high performance materials needed in advanced technologies. It presents interdisciplinary papers on the state of knowledge of each topic under consideration through a combination of overviews and original unpublished research. The volume contains eleven chapters divided into three sections: Chemistry; Chemical and Physical Properties; and Applications.
