✦ Synopsis

passed through the pot. Twenty-five grams of sodium dianilidosuccinate were added to the fused mass, and a temperature ranging from 23 °0 to 24 °0 C. was maintained for one and one-half hours. The resulting mass was dissolved in water, and air was blown through the solution. A precipitate of indigo formed and was collected on a filter. The indigo was 96.5 per cent. pure, and possessed satisfactory dyeing properties. The amount of indigo obtained was 60.4 per cent. of the theoretical yield from dianilidosuccinic acid, and 25 per cent. of the theoretical yield from fumaric acid.
