| titleOfInvention | Method for preparing scaling inhibitor |
| abstract | The invention discloses a method for preparing a scaling inhibitor. The scaling inhibitor is synthesized by the steps: (1) reacting glyoxylic acid and multi-amino compounds at the temperature of 50-70 DEG C for 2-4h, controlling pH (potential of hydrogen) to range from 8 to 10, and synthesizing an intermediate A; (2) reacting the intermediate A and glyoxal solution at the temperature of 30-50 DEG C for 0.5-2h to synthesize an intermediate B; and (3) reacting the intermediate B and hydrolyzed protein at the temperature of 50-70 DEG C for 2-4h, and controlling the pH to range from 8 to 9 to obtain a target product by means of drying. Application results indicate that the scaling inhibitor has fine scaling inhibition performance for calcium carbonate, calcium phosphate, barium sulfate and the like and can be applied to circulation cooling water and oil recovery flooding water with different concentration multiples, consumption of the scaling inhibitor is less, effects are fine, and benefits are high. Besides, the method extends the field of resource utilization of protein waste, and meets the requirement on sustainable development. |
