Embodiment 1
[0050] Preparation of iron p-toluenesulfonate:
[0051] In a 2000mL beaker, prepare a sodium hydroxide solution with a concentration of about 20% (be careful to let it cool). In another 2000mL beaker, add 400g CP ferric ammonium sulfate, add 1200g deionized water, and stir until it is completely dissolved. The sodium hydroxide solution is slowly added in the ammonium ferric sulfate solution, while constantly stirring, until the pH value is 7.5 (the pH value is measured with a pH meter), and a total of about 93g of CP solid sodium hydroxide is consumed, and a large amount of ferric hydroxide precipitation occurs at this time Move the ferric hydroxide precipitation into a 50L plastic bucket, add 3 times the volume of the precipitation to the deionized water, stir and wash for 2 minutes, let it stand for stratification, and drain the supernatant, and repeat the operation 5 times until the supernatant The electrical conductivity is less than 100us / cm. Put the washed ferric hydrox...

[0054] Preparation of iron p-toluenesulfonate:
[0055] In a 2000mL beaker, prepare a sodium hydroxide solution with a concentration of about 15% (be careful to let it cool). In another 2500mL beaker, add 400g of CP ferric ammonium sulfate, add 1600g of deionized water, and stir until it is completely dissolved. The sodium hydroxide solution is slowly added to the ammonium ferric sulfate solution, while stirring continuously, until the pH value is 7.0 (the pH value is measured with a pH meter), and a total of about 92.5 g of CP solid sodium hydroxide is consumed, and a large amount of ferric hydroxide is precipitated at this time appear; move the ferric hydroxide precipitate into a 50L plastic bucket, add 7 times the volume of deionized water of the precipitate, stir and wash for 5 minutes, let it stand for stratification, and drain the supernatant, and repeat the operation 6 times until the above The conductivity of the serum is less than 100us / cm. Put the washed ferric hydr...

[0059] Preparation of iron p-toluenesulfonate:
[0060] In a 2000mL beaker, prepare a sodium hydroxide solution with a concentration of about 30% (be careful to let it cool). In another 2000mL beaker, add 400g of CP ferric ammonium sulfate, add 600g of deionized water, and stir until it is completely dissolved. The sodium hydroxide solution is slowly added to the ammonium ferric sulfate solution, while stirring continuously, until the pH value is 9.0 (the pH value is measured with a pH meter), and a total of about 93.3g of CP solid sodium hydroxide is consumed, and a large amount of ferric hydroxide is precipitated at this time appear; move the ferric hydroxide precipitate into a 50L plastic bucket, add 5 times the volume of the precipitated deionized water, stir and wash for 3 minutes, let it stand for stratification, and drain the supernatant, and repeat the operation 10 times until the supernatant The conductivity of the liquid is less than 100us / cm. Put the washed ferric ...
