Sodium dodecyl benzene sulfonate is produced by sulfonating dodecylbenzene with fuming sulfuric acid or sulfur trioxide and then neutralizing with alkali. The disadvantage of sulfonation with fuming sulfuric acid is that there is always some waste acid in the sulfonated material after the reaction. The sodium sulfate generated after neutralization is carried into the product, which affects its purity. At present, the industry adopts the method of sulfonation with sulfur trioxide and air mixture. Sulfur trioxide can be evaporated from 60% fuming sulfuric acid, or sulfur and dry air are burned in a furnace to obtain a gas mixture containing SO34% to 8% volume fraction. This gas mixture is passed into a sulfonation reactor containing alkyl benzene for sulfonation. The sulfonated material enters a neutralization system to be neutralized with sodium hydroxide solution, and finally enters a spray drying system for drying. The product obtained is a powder with good flowability.
