Liquid-phase oxidation is discussed in terms of the free radical chain mechanism proposed by BOLLAND and his co-workers. This scheme was devised for certain oxidations in which hydroperoxide is the major product. It is shown, however, that this mechanism is applieable in its essentials to other oxid

✦ Synopsis
Data on the liquid-phase oxidation of isobutane a t 50 and 100°C have been reexamined, using a modified mechanism to take into account the termination by isohutylperoxy radicals. Algebraic expressions are derived from steady-state methods. Using Arrhenius parameters fitted by transition-state A factors and activation energies derived from observed "best" rate constants, new sets of parameters are derived for the rate constants for propagation by t-BuOz

## Abstract A study was made of the rate of liquid‐phase oxidation of ethanol to acetic acid. An aqueous, basic solution of ethanol was allowed to trickle over a palladium‐onalumina catalyst in a packed tower while oxygen‐containing gas was blown upward. The observed rates are described by an equat
