An adequate set of kinetic equations must describe the rate at which functional groups (epoxides, primary and secondary amines, hydroxy groups), rather than individual species (monomers, dimers, i-mers), evolve during reaction. This assumes that the rate at which a functional group reacts does not depend on the size (finite or infinite) of the molecule to which it is attached. The implication of this hypothesis may be understood if we write Eqs (5.6) and (5.7) in terms of the formation of an activated complex. 

The raw materials used to synthesize organic dyes are commonly referred to as dye intermediates. Largely, they are derivatives of aromatic compounds obtained from coal tar mixtures. The majority of these derivatives are benzene, naphthalene, and anthracene based compounds. This section provides an overview of the chemical reactions used to prepare the key intermediates employed in dye synthesis. In this regard, emphasis is placed on halogenated, aminated, hydroxy-lated, sulfonated, and alkylated derivatives of benzene, naphthalene, and anthraquinone.

Redistribution during thermal processing is a common self-reaction in condensation polymers such as PA, PEST, and PC that often contain nucleophilic amine, hydroxy, or phenolic end-groups, along with electrophilic groups such as amide, ester, or carbonate linking the individual monomer units. 

With A5 acids (such as the C20 acids in meadowfoam oil), the 8 lactone is formed in high yield when the acid is refluxed for 3 h with perchloric acid in dichloromethane. The proportion of 8 to y lactone depends on the reaction solvent. In hexane, the ratio is 6 1 and in dichloromethane almost 40 1. The 8-lactone is much more reactive than its y isomer. It can be converted to hydroxy amides (amines), hydroxy acids (alkali), and alkoxy esters (alcohol and acid) wifli the reagents indicated in parentheses.

A wide range of fluorescent derivatization reagents and techniques have been developed to utilize the analytical advantages that fluorescence offers. These derivatization reagents are usually specific to functional groups (e.g., amine, hydroxy, thiol), and their specificity offers yet another opportunity for discriminating against interferents. For excellent reviews, the reader is referred to references [38] and [39].
