Addition of neopentane to slowly reacting mixtures of H/sub 2/ + O/sub 2/ at 480/sup 0/C. Part II. The addition of the primary products from neopentane, and the rate constants for H and OH attack on neopentane. [Acetone, isobutraldehyde, isobutene oxide, 3,3-dimethyloxetan, and isobutene]
The relative rates of consumption of neopentane and of H/sub 2/ have been determined for small additions of neopentane to slowly reacting mixtures of H/sub 2/ + O/sub 2/ in aged boric-acid-coated vessels at 480/sup 0/C. Interpretation of the results gives rate constants for the attack of H and OH on neopentane at 480/sup 0/C. Combination of these values with independent measurements at lower temperatures gives Arrhenius parameters for these processes. Small amounts of the intermediates formed from neopentane have been added to slowly reacting mixtures of H/sub 2/ + O/sub 2/. The major initial products found when acetone, isobutyraldehyde, isobutene oxide, 3,3-dimethyloxetan, and isobutene are used as additives, have been determined. Mechanisms for the formation of many of the products are discussed. The results support the mechanism suggested in Part I for the oxidation of neopentane at 480/sup 0/C.
