Procedure

Chromic (III) chloride hexahydrate, 13.3 grams, was dissolved in 150 milliliters of ethanol. While this solution was being stirred, a solution of 2 grams of sodium hydroxide in 50 milliliters of ethanol was added. The mixed solution was refluxed for 15 minutes with stirring. Then, a solution of 2.6 grams of nitrophthalic acid in 50 milliliters of ethanol was added, and the reaction mixture was refluxed for 30 minutes with stirring. Thereafter, the by-product, sodium chloride, was removed by filtration. Thus, nitrophthalatotetrachromium (III) complex was obtained as an ethanol solution.
