Embodiment 1
[0018] Example 1: 3.64g of potassium hydroxide was weighed, and 20.0ml of deionized water was taken to prepare a potassium hydroxide solution, and 9.375g (8.93ml) of acrylic acid was neutralized under the conditions of cooling and stirring in an ice-water bath. Weigh 2.50g carboxymethyl potato residue, 3.125g acrylamide, 150.00mg potassium persulfate, 115.5mg sodium bisulfite, 25.00mg N,N'-methylenebisacrylamide, measure 25.0ml deionized water, All were added into the reactor, and the prepared acrylic acid and its potassium salt solution were poured into the reactor, and stirred at room temperature for 1.0 h to make it evenly mixed. Stir and heat under the protection of nitrogen, while controlling the heating rate to slowly increase the temperature of the water bath, and stop stirring when the temperature rises to 30-35°C. Afterwards, gradually increase the temperature, and when the water in the water bath reaches boiling point, continue heating to make it react within the tem...
Embodiment 2
[0019] Example 2: 2.91g of potassium hydroxide was weighed, and 20.0ml of deionized water was taken to prepare a potassium hydroxide solution, and 7.5g (7.14ml) of acrylic acid was neutralized under the conditions of cooling and stirring in an ice-water bath. Weigh 2.50g carboxymethyl potato residue, 7.5g acrylamide, 250.00mg potassium persulfate, 192.5mg sodium bisulfite, 30.00mg N,N'-methylenebisacrylamide, measure 25.0ml deionized water, All were added into the reactor, and the prepared acrylic acid and its potassium salt solution were poured into the reactor, and stirred at room temperature for 1.0 h to make it evenly mixed. Stir and heat under the protection of nitrogen, while controlling the heating rate to slowly increase the temperature of the water bath, and stop stirring when the temperature rises to 25-30°C. Afterwards, gradually increase the temperature, and when the water in the water bath reaches boiling point, continue heating to make it react within the tempera...
Embodiment 3
[0020] Example 3: 6.12g of potassium hydroxide was weighed, and 20.0ml of deionized water was taken to prepare a potassium hydroxide solution, and 13.125g (12.5ml) of acrylic acid was neutralized under the conditions of cooling and stirring in an ice-water bath. Weigh 2.50g carboxymethyl potato residue, 1.875g acrylamide, 100.00mg potassium persulfate, 77.0mg sodium bisulfite, 25.00mg N,N'-methylenebisacrylamide, measure 25.0ml deionized water, All were added into the reactor, and the prepared acrylic acid and its potassium salt solution were poured into the reactor, and stirred at room temperature for 1.0 h to make it evenly mixed. Stir and heat under the protection of nitrogen, while controlling the heating rate to slowly increase the temperature of the water bath, and stop stirring when the temperature rises to 40-45°C. Afterwards, gradually increase the temperature, and when the water in the water bath reaches boiling point, continue heating to make it react within the tem...
