Reaction of oxygen atoms with 1,3-butadiene has been investigated at room temperature. It is found that it conforms to the general mechanism established previously for the analogous reactions of monoolefins. Only 1,2-addition occurs, and the addition products, butadiene monoxide and 3-butenal, possess excess energy when formed as a result of high heats of reaction. The pressure dependence of the formation of the addition products yields the values of the "lifetimes" of the initially produced "hot" molecules. The relative rate constants have been determined at 25 and 127 °C and from these the relative values of the Arrhenius parameters have been calculated.

The relative rates of reactions of oxygen atoms with a number of olefins in the vapor phase determined in previous work are summarized and supplemented by some additional results. The uncertainty in the values of the relative rate constants is now believed to be reduced to only a few per cent. A number of simple correlations observed previously have been re-examined on the basis of the more complete and more accurate list of values available at present. These correlations show a distinct electrophilic character of oxygen atoms in their reactions with olefins and their potential significance for the understanding of the finer details of these addition processes is discussed.

Kinetics Of

Liquid 1,2-dichloroethane has been chlorinated by dissolved chlorine to a succession of chloroethanes up to the ultimate hexachloroethane. The results of both batch and continuous stirred tank reactor systems have been analysed by computer techniques to give a set of relative rate constants from which one can predict the product composition for a given chlorine uptake, the aim in this work being to optimize the production of tetrachloroethanes. An unusual feature of the kinetics is that 1,1,1,2- and 1,1,2,2-tetrachloroethanes provide alternative pathways between 1,1,2-trichloroethane and pentachloroethane.
