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 to synthesize new biobased reactants with various function and functionality with reaction conditions in agreement with green chemistry principles: it does not use neither solvent nor initiator or need simple purification step, feasible at industrial scale. Esterification and amidification were also used to insert ester or amide groups in fatty chains in order to modifiy properties of thereof synthesized polymers. Building blocks synthesized have various functions and functionality: polyols, polyacids, polyamines and dicyclocarbonates from vegetable oils and from glycerine derivatives. They were used for the synthesis of biobased polyurethanes, polyhydroxyurethanes and epoxy resins.
