The decomposition of n‐butyl acetate on charcoal was studied at 365° and 385°C, and isobutyl acetate at 394° and 419.5°C. Isobutene and acetic acid were the principal products from the iso ester, and n‐butenes and acetic acid from the normal ester. Other primary and secondary reactions exceeded 20% in most experiments. The principal primary product from the normal ester was 1‐butene which isomerized subsequently to 2‐butenes; iso‐butene from the iso ester did not isomerize. For both esters the activity of the charcoal decreased rapidly, the conversion decreasing linearly with time. Linear correlations were used to estimate the conversion at zero time, and data at zero time were used to evaluate constants of a rate equation. Fouling was attributed to reactions of olefins which produced carbonaceous residues.
