Epoxidation: Succinic acid is first epoxidized to produce epoxysuccinic acid.
Etherification: Epoxysuccinic acid is then treated with an alkali metal hydroxide to form the sodium salt and then etherified with an alcohol.
Hydrolysis: The resulting etherified product is hydrolyzed to produce Sodium Polyepoxysuccinic Acid.

Frequently Asked Questions

Application features of Sodium of Polyepoxysuccinic Acid(PESA)?
1. Scale inhibition performance of PESA
Experiments show that PESA has a solubility-limiting effect on the deposition of calcium sulfate scale, and its scale inhibition rate increases with the increase of dosage. When the concentration reaches a certain concentration, the scale inhibition ability no longer increases significantly.
The anti-calcium carbonate scale of PESA is better than some commonly used polycarboxylates, sulfonates, and polyphosphoric acid scale inhibitors.
2. Corrosion inhibition performance of PESA
When PESA is used alone, a lower dosage has a certain corrosion inhibition effect on carbon steel. With the increase of PESA concentration, its corrosion inhibition effect is also enhanced, the corrosion rate of carbon steel decreases gradually, and the corrosion inhibition rate increases. To achieve better corrosion inhibition effect, the required PESA mass concentration is higher.
When PESA is used alone as a corrosion inhibitor, its performance is inferior to other organic phosphoric acid corrosion inhibitors, but because it does not contain phosphorus, it can be compounded with other agents to form low-phosphorus or phosphorus-free organic corrosion inhibitors. Studies have found that PESA has a good synergistic effect with inorganic phosphates, organic phosphates, and benzotriazoles, and the corrosion inhibition effect after compounding is significantly enhanced.

Application range of Sodium of Polyepoxysuccinic Acid(PESA)?
1. PESA is suitable for oilfield water injection, crude oil dehydration, boiler water treatment and other fields.
2. PESA is suitable for water treatment of circulating cooling systems in steel, petrochemical, electric power, pharmaceutical and other industries.
3. PESA is especially suitable for boiler water treatment, circulating cooling water treatment, seawater desalination and membrane separation of high alkalinity, high hardness, high pH and high concentration ratio systems.
4. PESA is suitable as a washing aid.
