Nitro Delta Acid

Condensation and addition. In both condensation and addition reactions, two or more molecules combine by the elimination of a simple molecule (condensation), or the reaction is stopped after the molecules are joined (addition). There are only a few intermediates manufactured in any considerable quantity by these reactions. An example of a condensation reaction is the formation of the diphenylamine derivative, commonly called nitro delta acid [5]. 

Condensation, In a restricted sense, condensation describes those reactions in which a carbon-carbon bond is formed by the elimination of a simple molecule. An example is the condensation of benzanthrone to dibenzanthrone, shown below in Fig. 23.6 and described on page 909. Dye intermediate chemical terminology uses the term condensation more broadly than this to describe a variety of reactions in which molecules are joined the bonds formed are not restricted to carbon-carbon. An example is the formation of the diphenylamine derivative, commonly called Nitro Delta Acid ...
