The heterogeneous reaction between SO 2 and unsaturated compounds results in the efficient production of organosulfates for several fatty acids and long‐chain alkenes. The presence of an acid group, the physical state of the reactants (solid or liquid), the nature of the double bond ( cis , trans , terminal), and the use of light irradiation all have an impact on the reaction rate. The reaction was investigated using different set‐ups (coated flow tube, aerosol flow tube, and diffuse reflectance infrared Fourier transform cell). The reaction products were identified by high‐resolution mass spectrometry and the impact of this reaction on organosulfate formation in the atmosphere is discussed.
