Abstract: The reaction of dehydroabietic acid and DMSO produced a new compound when they were heated to 215 ℃ for 3 h in the presence of KOH catalyst. The structure of the reaction product has been characterized by UV, IR, NMR and MS analysis to be methylthiomethyl dehydroabietate. The possible reaction mechanism has been proposed based on the reaction between DMSO and acetic acid or acetic anhydride. The acid was firstly dehydrated to form acid anhydride. Then it reacted with DMSO to produce the ester via. Pummerer rearrangement.

Key words: dehydroabietic acid, DMSO, characterization
