| Abstract | Methyl laurate used in this study as an original fatty ester) was easily converted to a 1 molar SO 3 adduct (first intermediate) by adding SO 3 at −20°C. This intermediate was found to be in equilibrium with the original ester. The energy of addition of SO 3 to form the intermediate was about 14 kcal/mol based on exchange rates of the equilibrium. Sulfonation of the α-position of an ester occurred not on the original ester but on the first intermediate to give a 2-molar SO 3 adduct (second intermediate). The α-sulfonation followed kinetically the second order for the first intermediate and had an activation energy of about 25 kcal/mol |
