✦ Synopsis

plished with the system propionic acid/water/carbon tetrachloride in a flow apparatus specially developed for this purpose [21. The resulting kinetic data are plausible if the boundary layer reaction occurring on transfer of a caroxylic acid is formulated as a series of three individual reaction stepsW For the passage through the boundary layer from water to carbon tetrachloride, these steps are: 1) Adsorption of the carboxylic acid molecule, which exists as the monomer in water;

2. dimerization of the adsorbed molecules; and 3) desorption of the dimer into the c c 1 4 phase.

The same processes occur in the reverse order on passage in the opposite direction. The dependence of the rate constants on the length of the fatty acid residues lends support to the above interpretation. This dependence corresponds quantitatively to established adsorption phenomena.
