General procedure for the synthesis of 1,3-benzenediacetic acid from 1,3-benzenediacetonitrile: 25 mL of concentrated sulfuric acid was diluted with 35 mL of water, followed by the addition of 24 g of 1,3-benzenediacetonitrile, and the reaction was carried out at reflux for 1 hour and 30 minutes. Upon completion of the reaction, the reaction mixture was poured into 200 mL of ice water and the precipitated crystals were collected by filtration and washed with cold water. Finally, the resulting crystals were dried under reduced pressure at 100 °C for 1 h to give 27 g of 1,3-benzenediacetic acid.
