Reactions of Hydroxyl Radicals and Chlorine Atoms with Compounds of Group Iv Elements


Book Description

Rate data are reported for the reaction of hydroxyl radicals with a series of substituted silanes. The data presented suggest the presence of polar effects in the transition state. Good agreement is reported between a relative rate study and an absolute rate study, Table (i). The corresponding reaction of chlorine atoms with the series of substituted silanes support the suggestion of polar effects in the transition state, Table (ii). Rate data are also reported for the reaction of hydroxyl radicals with a series of tetramethyl and tetraethyl compounds of the Group IV elements. The data presented show an enhanced reactivity along the series from tetraalkylcarbon to tetraalkylcarbon to tetraalkyllead. Good agreement is reported between a relative rate study and an absolute rate study, Table (iii). The corresponding reactions of chlorine atoms also demonstrate enhanced reactivity along the series from tetraalkylcarbon to tetraalkylead, Table (iv).




The Mechanisms of Atmospheric Oxidation of the Alkenes


Book Description

The formation of smog in urban atmospheres involves the interaction of sunlight with an air mixture containing nitrogen oxides and reactive hydrocarbons -- the most reactive class of these hydrocarbons being alkenes. This important new book, by a team of leading atmospheric chemists, reviews and evaluates the existing literature on the atmospheric chemistry of these compounds, focusing on the search for a more quantitative understanding of the phenomenon which can then be applied to control methods. It includes detailed examinations of the reactions of alkenes and even suggests areas for further laboratory studies. This book is ideal for climatologists, meteorologists, and scientists studying the chemistry of the atmosphere and can also serve as a valuable text for graduate courses in atmospheric chemistry and atmospheric science.







Reaction Kinetics and the Development and Operation of Catalytic Processes


Book Description

Reaction Kinetics and the Development and Operation of Catalytic Processes is a trendsetter. The Keynote Lectures have been authored by top scientists and cover a broad range of topics like fundamental aspects of surface chemistry, in particular dynamics and spillover, the modeling of reaction mechanisms, with special focus on the importance of transient experimentation and the application of kinetics in reactor design. Fundamental and applied kinetic studies are well represented. More than half of these deal with transient kinetics, a new trend made possible by recent sophisticated experimental equipment and the awareness that transient experimentation provides more information and insight into the microphenomena occurring on the catalyst surface than steady state techniques. The trend is not limited to purely kinetic studies since the great majority of the papers dealing with reactors also focus on transients and even deliberate transient operation. It is to be expected that this trend will continue and amplify as the community becomes more aware of the predictive potential of fundamental kinetics when combined with detailed realistic modeling of the reactor operation.
