Autoxidation drying starts when all solvent is evaporated. Consequently,
autoxidation takes place in a mixture of pure alkyd resin and pigments, which is very
likely a significantly apolar environment. This has some consequences for the
autoxidation reactions, i.e. ionization processes will be suppressed and metal salts will not
dissociate into ions.[9] The most notable consequence for autoxidation of the alkyd system
is that the Haber-Weiss reactions 3 and 4 do not occur in apolar media. Hydroperoxides
are decomposed following metal-hydroperoxide complex formation, as shown in scheme
1.3.[9, 10, 14, 35, 36] This has some far-reaching implications for metal catalysis, since
reaction 4b in scheme 1.3 has been reported to be very slow for simple metal salts.[10]
