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.
Claims20
A process for a reactive separation of organic molecules from biomass comprising:
- contacting biomass with a base and a solvent;
- extracting products from the biomass with the solvent based on a reaction of the base with the biomass to form a slurry;
- filtering the slurry to recover a liquid product, wherein the liquid product comprises:
- a) a ferulate, a coumarate, ferulic acid, coumaric acid, or any combination thereof, and b) a fatty acid compound comprising a fatty acid, a fatty acid ester, or any combination thereof;
- and
- removing at least a portion of the fatty acid compound from the liquid product to produce a purified liquid product comprising the coumarate, the ferulate, the ferulic acid, the coumaric acid, or any combination thereof.
