Examples
Embodiment 1
[0086] Add 40mL of ethylene glycol to a 100mL three-necked flask, add 0.5g of PSSMA (3:1) under mechanical stirring (1180rpm) and continue stirring for 10 minutes, then add 1.084g of ferric chloride hexahydrate and continue stirring for 10 minutes. Immediately afterwards, 3.0 g of sodium acetate trihydrate was added and stirring was continued for 30 minutes. After the solution changed from yellow to brownish red, the reaction solution was transferred to a 100 mL reactor and reacted in a closed manner at 200° C. for 10 h. After the reaction, it was cooled to room temperature, and the product was washed and magnetically separated with deionized water three times, and then dispersed in 20 mL of deionized water (concentration: 13.68 mg / mL). The solid product in the solution was 273.5 mg.
Embodiment 2
[0088] The difference between this example and Example 1 is that the dosage of PSSMA (3:1) is 1.5g. The prepared product was washed with deionized water and magnetically separated for three times, and then dispersed in 20 mL of deionized water (concentration: 13.03 mg / mL). The solid product in the solution was 260.6 mg.
Embodiment 3
[0090] The difference between this example and Example 1 is that the dosage of PSSMA (3:1) is 2.5g. The prepared product was washed with deionized water and magnetically separated for three times, and then dispersed in 20 mL of deionized water (concentration: 11.18 mg / mL). The solid product in the solution was 223.6 mg.
