2-Methyl-5-nitrobenzenesulfonic acid Use and Manufacturing

Methods of Manufacturing

Derived from p-nitrotoluene sulfonation. Inhale the molten p-nitrotoluene into a glass-lined reaction pot, add 980kg 20% fuming sulfuric acid, and control the temperature not to exceed 90°C. After the addition, the temperature is increased to 105-110°C and kept for 1 hour. After the reaction is completed, it is cooled to 70°C and diluted with water. Stir at below 100°C for 30min, cool to 25°C, adjust the acidity and filter. The filter cake is 2-methyl-5-nitrobenzenesulfonic acid.

Uses

This product is an optical brightener and dye intermediate.
