Steps:
2.2. Catalytic activity evaluation
10 g Diethanolamine, 2 g catalyst, and 8.5 g sodium hydroxide (dissolved in 80 mL deionized water) were added to a high-pressure reactor. The airtightness of the reactor was checked, and then N2 was passed and emptied 5-6 times before pressurizing to 1 MPa. The temperature was raised to 160 °C at a heating rate of 4 °C/min, and stirring was carried out at a speed of 400 rpm. The volume of hydrogen discharged was measured by a rotameter. The exhaust valve was opened when the air pressure reached 1.5 MPa and then closed when the pressure dropped to 1 MPa. The volume and exhaust temperature of each exhaust were recorded. During reactions, if the pressure in the reactor did not change for 20 min, the reaction was regarded as complete. Liquid chromatography was used for qualitative analysis. The yield of iminodiacetic acid was calculated using a strong anion exchange column (Hypersil SEX, 5 μm, 4.6 mm × 250 mm). The calculation of the yield of iminodiacetic acid is described in detail in the Supporting Information.
