Abstract
A process for a reactive separation of organic molecules from biomass includes a reaction step for the biomass, a simultaneous extraction step using a solvent, and a filtration step to recover products, wherein the products comprise ferulic acid and/or coumaric acid. The products are extracted from the biomass in a pressurized stirred batch reactor using a liquid extraction solvent and a base in which the ferulate and the coumarate remain.
