摘要：
Suggested is a process for preparing sulfates and/or sulfonates by adding sulfur trioxide to a compound comprising at least one hydroxyl function and/or at least one double bond, which is characterized in that (i) the reaction is performed in a micro-reaction system (μ-reactor), (ii) the sulfation/sulfonation agent used is a liquid sulfur trioxide, and (iii) the reaction is conducted in the presence of 0 to 20 Vol.-% of air, inert gas or organic solvents.
