PRODUCTION OF HIGHLY PURE META,META-COUPLED BIS(4-ALKYLPHENOL) DERIVATIVES AND USES THEREOF
20210070684 · 2021-03-11 ·

In general the present invention concerns a method for production of highly pure m,m-coupled bis(4-alkylphenol) derivatives from particular lignin-derived 4-alkylphenol derivatives. More specifically this invention relates to a process for the selective purification of m,m-coupled bis(4-alkylphenol) derivatives by selective crystallization in the presence of residual substrate and isomeric and/or oligomeric by-products/impurities. This new class of bis(4-alkylphenol)s are valuable precursors for renewable thermoplastics, (high temperature) resins/thermosets, bio-derived C.sub.15-C.sub.19 fuel additives, antioxidants, UV-stabilizers, plasticizers, soluble n-type perylene copolymers and/or positive working photoresists.
