실험 절차

With total consumption of the fluorescein, the bromination reaction leads to the formation of a single product, tetrabromofluorescein (4Br—F), the disodium salt of which is commercially known as Eosin Y. The final reaction mixture is diluted in water and the product is extracted from the mixture with ethyl acetate.
