An aromatic alcohol used as a chemical intermediate Resorcinol is an important organic synthetic raw material, mainly used in rubber adhesives, analytical reagents, preservatives, drugs, dyes, synthetic resins and other raw materials. For example, eosin is an important triphenylmethane dye that is dyed bright red. It is mainly used for dyeing silk. It is prepared by co-heating resorcinol and phthalic anhydride in the presence of zinc chloride or concentrated sulfuric acid to prepare the intermediate fluorescent yellow, and then tetrabromination. Eosin is commonly used to make red ink and can also be used as a stain for microscopic examination of biological materials.
