WebPhthalic anhydride is one of the source products for organic synthesis. Phthalic anhydride is made in the coking industry by the catalytic vapor-phase oxidation of naphthalene. The product is difficult to isolate from the reaction mixture leaving the static-bed catalytic reactors, since the volume of gases and vapors to be cooled is very large ... WebThe reaction of phenol with phthalic anhydride is an electrophilic substitution reaction. Therefore, when phenol is heated with phthalic anhydride in the presence of conc. H2SO4, the product we get is phenolphthalein. Phenolphthalein is commonly used in the acid-base titrations because of its unique characteristic of giving different colours in ...
