Case 1: Dyeing in the Textile Industry
A textile factory used 1,8 - dihydroxy anthraquinone as an intermediate to synthesize a new type of red dye. They followed a carefully designed synthesis process. First, they weighed 100 grams of 1,8 - dihydroxy anthraquinone and added it to a reaction flask containing 500 ml of ethanol. Then, they added other reactants step - by - step under heating and stirring conditions at 70 °C for 5 hours. After purification, they obtained a high - quality red dye. They dyed cotton fabrics with this dye and found that the dyed fabrics had excellent color fastness, with a color difference of less than 1 after 20 times of washing, which met the high - end market requirements.
Case 2: Pharmaceutical Research
A research team was studying the anti - inflammatory properties of 1,8 - dihydroxy anthraquinone. They dissolved 50 mg of the compound in 10 ml of dimethyl sulfoxide (DMSO). Then, they added different concentrations of the solution to cell cultures of macrophages. After 24 hours of incubation, they measured the production of inflammatory cytokines. They found that at a certain concentration, 1,8 - dihydroxy anthraquinone could significantly inhibit the production of inflammatory
