Case 1: Dye Synthesis
A textile dye manufacturing company used anthraquinone - 2 - carboxylic acid as an intermediate to synthesize a new type of blue dye. They dissolved anthraquinone - 2 - carboxylic acid in a mixture of ethanol and acetic acid, and then added some specific amines and catalysts according to a certain ratio. After a series of heating and reflux reactions, a new blue dye with high color fastness was obtained. This dye was tested on cotton fabrics, and the test results showed that it had excellent color retention and washing resistance, which greatly improved the quality and market competitiveness of the company's textile products.
Case 2: Pharmaceutical Synthesis
A pharmaceutical research institution was engaged in the research of anti - tumor drugs. They used anthraquinone - 2 - carboxylic acid as a starting material to synthesize a new type of anti - tumor compound. Through a series of complex chemical reactions, including esterification, amination and cyclization, a compound with potential anti - tumor activity was obtained. In vitro cell experiments showed that this compound could effectively inhibit the growth of certain tumor cells, laying a foundation for the development of new anti - tumor drugs.
