PROCESS FOR PRODUCING VALUE ADDED LIGNIN BASED CHEMICALS FROM ALKALINE EFFLUENT OF CHEMICAL TREATMENT OF LIGNOCELLULOSIC BIOMASS

WIPO Patent Application WO/2016/123520

A3

The invention discloses a novel process to make hydrophobic interaction between lignin and ABA-block-copolymers, providing solubilization or encapsulation of the lignin in block copolymer micellar systems and utilizing the micellar systems to perform chemical reaction with non-polar or polar agents. The result is that solubilization and interaction of hydrophobic phenolic compounds with PEO/PPO copolymer micelles in water emulsions enables high value lignin derivatives from lignin pretreatment effluent in biorefineries to be produced.
