  • Publication number: 20220033341
    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.
    Type: Application

  • Publication number: 20200317593
    Abstract: A process for processing lignin includes contacting a mixture comprising lignin and/or lignin-like molecules with a catalyst to form a reaction mixture, and producing one or more reaction products. The reaction mixture comprises one or more aliphatic alcohols, and the one or more reaction products are selected from the group consisting of: 2-methoxy-4-propylphenol (DHE), 2,6-dimethoxy-4-propylphenol (DMPP), 4-(3-hydroxypropyl)-2,6-dimethoxyphenol (DMPP-OH), 4-(3-hydroxypropyl)-2-methoxyphenol (DHE-OH), 2,6-dimethoxy-4-(prop-1-en-1-yl)phenol (i-DMPP), 2-methoxy-4-(prop-1-en-1-yl)phenol (isoeugenol), and mixtures thereof.
