Catalysis by hydrogen halides in the gas phase. XVI. Methyl trimethylacetate, isopropanol, and hydrogen bromide

Abstract

In the presence of hydrogen bromide at 407º, methyl trimethylacetate decomposes to isobutene, carbon monoxide, and methanol. Isopropanol reacts with an intermediate to form isopropyl trimethylacetate, which decomposes quickly to propene. Methanol competes effectively with isopropanol. Some ratios of individual rate constants are obtained from the rate reductions in the competition reactions.
