Abstract The hydrolysis of t-butyl formate in aqueous acid solution has been studied over the range 35–83°. At low concentrations of catalysing acid, specific hydronium-ion catalysis is enhanced by the formic acid produced during the reaction. A series of oxygen-18 tracer experiments was performed, taking into account the formation of isobutylene, which is a by-product of hydrolysis by alkyl-oxygen fission. The percentage alkyl-oxygen fission varies from 3 at 35° to 40 at 76°. Catalytic rate constants for reactions by the AAL1 and the AAC2 mechanisms are expressed respectively by the equations k′1 = 1016.6exp(−28000/RT) 1. mole−1 sec−1 k′2 = 107.8exp(−13600/RT) 1. mole−1 sec−1 The rate constants found for the BAL1 mechanism are of order-of-magnitude significance only.
