Synthesis of bio-based building blocks from vegetable oils: A platform chemicals approach

摘要

This review reports the synthesis of various building blocks from vegetable oils in one or two-steps syntheses. Thiol-ene coupling allows the synthesis of new biobased reactants with various functionalities using reaction conditions in agreement with green chemistry principles: it does not use solvent or initiator or need simple purification step and is feasible on an industrial scale. Esterification and amidation were also used to insert ester or amide groups in fatty chains to modify the properties of the synthesized polymers. The building blocks synthesized have various functions and include polyols, polyacids, polyamines and dicyclocarbonates from vegetable oils and from glycerol derivatives. Tlwse were used for the synthesis of biobased polyurethanes, non-isocyanate polyurethanes and epoxy resins.
