实验过程

Into a 2-liter round-bottom flask was put 62.8 g of N-phenyliminodiacetic acid under nitrogen gas stream to dissolve with 500 ml of toluene. To the solution was added 32.0 g of acetic anhydride, and the mixture was refluxed by heating with stirring. After lapse of one our, the mixture was cooled to room temperature and 3 liters of hexane was added thereto with stirring to deposit. The deposit was collected by filtration to obtain 52.0 g of N-phenyliminodiacetic acid anhydride.
