 Title    High Pressure Reactions, I Evidence for Two Concurrent Mechanisms in Lewis-Acid Catalyzed Alkylation of Aromatics with Olefins  
 Abstract    A kinetic study was made of the primary step of the alkylation of benzene with propy-lene and ferric chloride as catalyst under homogeneous reaction conditions at several pressures up to 2 kbar. Initial reaction rate of cumene formation shows a minimum in the medium pressure range, thus indicating that product formation occurs via two different reaction paths with opposite pressure de-pendence.

 Title    Photomineralisierung chlorierter Alkane, Alkene und Aromaten an Kieselgel Photomineralization of Chlorinated Alkanes, Alkenes and Aromatics on Silica Gel  
 Abstract    The photodegradation to C02 (photomineralization) of chlorinated alkanes, alkenes and aromatics adsorbed on silica gel was examined. In addition to CO2, CI" and Cl2 were determined. The degradation depends considerably on the activity of the surface and decreases in the order alkenes > alkanes > aromatics.
