... Rosin maleic anhydride adduct (R-MA) can be prepared as previously reported [10]: Gum rosin (0.33 mol; 100 g) was heated to 180 o C and maintained at this temperature for 1 h under the nitrogen atmosphere. ... Gum rosin was used as starting material to synthesize the R-MA. ...

 
The rosin as natural product became a source for production of eco friendly biosurfactants which widely used in environmental protection issues. In this respect, nonionic surfactant was prepared fromreaction of rosin maleic anhydride acid chloride with triethylene tetramine followed by etherification with poly (ethylene glycol600 to produce etherified rosin imide (ERIT-PEG) surfactant.
