%X 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.
