Note    (1), Avoid using in children cleaning products, such as: shampoos, shower gels.
Synthesis
Currently, sulfonation reaction through continuous reactor (such as: falling film reactor) is the most widely used method for preparing sulfonates.
Generally, C10-16 alkylbenzene and sulfur trioxide react through reactor, finally obtain product.
US patent 8,921,588 (Process for preparing sulfates and/or sulfonates in a micro-reaction system) presents a synthetic process. Conditions: mole ratio of sulfur trioxide and alkyl benzenes or other raw materials: 1:1; temperature: 30-60°C; reactor: falling film reactor.
