Synthesis of sodium maleopimaric acid (A02)
Sulfate surfactants (A03-A05) are often prepared by the esterification of hydroxyl
derivatives of rosin by sulfonate reagents. Chlorosulfonic acid was chosen as a
sulfonating reagent to react with rosin-based alcohol. After neutralisation by an
alkali or tertiary amine, rosin-based anionic surfactants were obtained (

). Concentrated sulfuric acid was also chosen as a sulfonating reagent to react
with rosin-based alcohol [34].
