1. Basic properties
Sulfonic acid powder is a medium-strength inorganic acid whose acidity is between sulfuric acid and phosphoric acid. It has a stable crystal structure and is not easy to decompose at room temperature, but it will be gradually hydrolysed to produce ammonium sulphate at high temperature. Powdered sulphonic acid is soluble in water, the aqueous solution is acidic and less corrosive to metals, which gives it an advantage over sulphuric and hydrochloric acids in many applications.
2. Production process
The industrial production of sulphonic acid powder is mainly made by reacting urea with fuming sulphuric acid. The steps are as follows: urea and fuming sulphuric acid react at high temperature to form sulphamic acid. The reaction product is cooled, crystallised, filtered and dried to obtain pure sulfonic acid powder. The process is simple and efficient, but requires strict control of the reaction conditions to ensure product quality.
Sulfonic acid powder is a multifunctional chemical that plays a significant role in industrial production and daily life. Its high efficiency, low corrosiveness and wide range of applications make it an indispensable raw material for many industries. With the improvement of environmental protection requirements and technological progress, the production and application of sulfonic acid powder will develop in a greener and more efficient direction.
