Abstract
The kinetics of the oxidation of
long-chain unsaturated compounds when spread as monolayers on KMnO4 solutions has been determined from
measurements of the changes in area with time. The effects of number of double
bonds (unconjugated),of chain length, and of permanganate concentration were
studied, as well as the behaviour of the dihydroxy compounds believed to be the
first stage of the oxidation process.
The velocity constant
has been found to increase markedly for each additional double bond, and to be
independent of chain length, thus providing a quantitative measure of degree of unsaturation in
unconjugated long-chain compounds.
Mixed films of
unsaturated and dihydroxy acids have been studied and the results used to allow
for deviation from additivity of areas in the reacting systems. On this basis
the overall area-time curve, which goes through a maximum, has been
quantitatively accounted for.
