실험 절차

A mixture of magnesium hydroxide (433 mg, 7.46 mmol; Aldrich) and taurine (1.87 g, 14.9 mmol) in 20 ml water was heated under reflux for seven hours. The resulting milky mixture was allowed to cool, diluted with 40 ml methanol and allowed to stand overnight at room temperature. A white powder, consisting mostly of magnesium taurate complex, was removed by filtration. The clear filtrate was concentrated under vacuum to a pasty slurry, then diluted slowly with 10 ml methanol. After 2 hours, crystalline magnesium taurate salt was obtained by filtration. The yield was 940 mg (41%). The melting point (decomposition) was about 300° C. This salt was identical to that obtained in Example 2.
