An apparent zero order reaction for heat-induced changes of the color parameter L has been determined by various authors such as Kanterewicz and Chirife (1986) in cheese whey, using L* and other color parameters, Bates et al.
Under zero order reaction, the frequency factor is directly proportional to the reaction rate.
Furthermore, as a first approximation, the dehydrochlorination step can be considered a zero order reaction because, again, the concentration of Cl in the polymer does not change significantly.
