The kinetics of amidosulfonate hydrolysis was studied. The catalytic effect of hydrogen ions on the hydrolysis reaction and the salt effect of hydrolysis were analyzed. The hydrolysis reaction of amidosulfonate showed a negative salt effect in the studied ionic strength. The kinetic equation for the hydrolysis of potassium trisammonosulfonate (NTS) is: dc NTSdt = k NTSc NTSc H +, k NTS = 3.5 at a temperature of 30 ° C ~ 67 ° C and an ionic strength of I = 0.05 mol / L 77 × 109e-5.460 × 10 4 / RTL / (mol · s); The kinetic equation of hydrolysis of potassium amidodisulfonate (IDS) is: - dcIDSdt = k IDSc H + c IDS at 32 ° C ~ 72 ° C, k IDS = 1.40 5 × 10 17e-1.0 65 × 10 5 / RTL / (mol · min) at an ionic strength of I = The kinetic equation for the hydrolysis of SA was as follows: - dc SAdt = k SAc H + c SA k SA = 7.964 × 10 at 5 0 ° C ~ 84 ° C and ionic strength I = 0.05 mol / L 17e-1.2 77 × 10 5 / RTL / (mol · min)
