实验过程

In this example a mol-for-mol combination of phthalic anhydride (I) and N,N-diethylaniline (T) are reacted, as disclosed previously, to yield the keto acid (II). The keto acid is similarly reacted with N-vinyl carbazole to yield the title compound. The title compound imparts a blue-yellow color to paper coated with a phenolic resin or silton clay or a combination of the two. A reflectance spectrum of the blue-yellow color has an absorption peak at 630 nanometers.
