Acetophenone synthetic resins

Acetophenone, C Hg. CO. CH3, is a ketone occurring in oil of lab-danum resin. It also occurs in the oil of Stirlingia latifolia which contains over 90 per cent, of the ketone. It is a fragrant, crystalline substance melting at 20° and boiling at 200° to 202°. It is prepared artificially and is useful in synthetic perfumery. As found in commerce... 

The natural resin most commonly used as a binder today is rosin, which is often tailored by chemical modification to suit specific applications. Also, many synthetic hard resins mainly based on cyclohexanone, acetophenone, or aldehydes, are used in the paints industry. Hard resin binders increase the solids content, accelerate drying, and improve surface hardness, luster, and adhesion. 

Machalkova [643] has described analysis of polymer composites and rubber blends with emphasis on separation of low-MW additives by instrumental methods. Examples refer to analysis of inorganic filler- or synthetic fibre-reinforced plastics and laminated plastic Aims using PyGC and IR. The versatility of PyGC has further been exemplified by Jones [633] as a thermovolatilisation technique for direct determination of occluded volatiles and low-MW additives in lube oil, novolac resins and HDPE, of plasticisers and vinylchloride in PVC, and of solvent residues in paints and bitumens, etc. Dicumylperoxide (DCP) in LDPE was identified through detection of three main by-products of reaction, acetophenone, a-methylstyrene and 2-phenylpropan-2-ol [633].
