Current regulations require the substitution of toxic solvents by safer ones. Succinic acid diesters, which are among promising bio-based candidates, have been compared to petrochemical solvents through two complementary approaches. The first one deals with a prediction of solvents dissolution power based on Hansen Solubility Parameters (HSP). HSP values obtained with the model developed by Stefanis-Panayiotou showed good agreement with experimental miscibility maps. The second one explores the physicochemical properties with multivariate statistical methods. Principal Components Analysis and Agglomerative Hierarchical Clustering led to a partition of green solvents into clusters together with toxic solvents, suggesting favourable substitutions in further applications.
