FAQ

Q1

What are the main synthesis methods of naphthalene sulfonic acid?

Answer: The main synthesis method of naphthalene sulfonic acid is through the sulfonation reaction of naphthalene. Naphthalene reacts with sulfuric acid at appropriate temperature and pressure to produce naphthalene sulfonic acid and water. This reaction usually requires the presence of a catalyst, such as iron sulfate or aluminum sulfate, to promote the reaction.

Q2

What are the characteristics of naphthalene sulfonic acid as a surfactant?

Answer: As a surfactant, naphthalene sulfonic acid has excellent wetting, dispersing, and cleaning properties. It can reduce the surface tension of water, making it easier for water to penetrate the solid surface, thereby playing a wetting role. Meanwhile, naphthalene sulfonic acid can also disperse insoluble substances such as oil and dirt in water, making it easy to clean and remove.

Q3

What is the role of naphthalene sulfonic acid in metal surface treatment?

Answer: Naphthalene sulfonic acid can clean and treat metal surfaces in metal surface treatment. It can react with oil stains, oxides, etc., on metal surfaces, converting them into soluble compounds to remove these pollutants. The treated metal surface is cleaner and smoother, improving the metal's corrosion resistance and service life.

Q4

What are the applications of naphthalene sulfonic acid in oilfield chemicals?

Answer: In oilfield chemicals, naphthalene sulfonic acid can be used as a raw material for drilling fluids, completion fluids, etc. It has good dispersibility and stability, which can help to evenly distribute drilling fluid in underground rock layers, reduce friction and resistance, and improve drilling efficiency. Meanwhile, naphthalene sulfonic acid can also be used with other additives to improve drilling fluids' rheological properties and stability.

Q5

How to store and transport naphthalene sulfonic acid to ensure its stability?

Answer: To ensure the stability of naphthalene sulfonic acid, attention should be paid to avoiding high temperatures and humidity during storage and transportation. It is recommended to store naphthalene sulfonic acid in a dry, cool, and well-ventilated place, away from fire and heat sources. During transportation, moisture-proof and sun-protection measures should ensure the packaging is intact and undamaged, avoiding leakage and damage.
