    sulfonation of Linear Alkylbenzene LAB with sulfur trioxide SO 3. In industry, multi-tube falling film reactors are used for this purpose. In such reactors a diluted gaseous stream of SO 3 in dry air is contacted with liquid LAB while both reactants flow co-currently downward. The reaction is highly exothermic and product quality depends.AIR-S03 SULFONATION amp SULFATION PROCESS 202 Introduction TO ----- Anhydrous SO3 is used to sulfonate aklylbenzenes and to sulfate alcohols and alcohol ethoxylates converting them to surface active agents. The acids produced are neutralized with NaOH, ammonia and other bases as described in process.The plant was designed using the latest technology based on a continuous airSO 3 sulfationsulfonation process that guarantees its products meets the strictest standards required by the Household and Personal Care Industries for anionic surfactants.
