The rate of decarbonylation of mesitaldehyde was determined by a gasometric method in 70 to 102.9 H sub2 SO sub4 at 100 deg C. In 70 to 96 H sub2 SO sub4 the reactions indicated unimolecular rearrangements of the conjugate acid the reactions in 96 to 100 H sub2 SO sub4 suggested a higher molecularity involving 1 or more solvent species. The comparitive rates of decarbonylation of mesitald-hyde, 2,4,6-triethylbenzaldehyde, and 2,4,6- triisopropylbenzaldehyde were 1 to 4.1 to 17.7.
