摘要： 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.

摘要： A process for synthesizing (S,S) ethylenediamine-N,N′-disuccinic acid (EDDS) includes combing an aqueous solution of aspartic acid with dibromoethane under basic conditions to form a reaction solution; heating the reaction solution to form a heated reaction solution, and recovering at least a portion of the reaction product from the reaction solution. The heated reaction solution comprises a reaction product, wherein the reaction product comprises (S,S) ethylenediamine-N,N′-disuccinic acid (EDDS).

摘要： A process for a reactive extraction and subsequent purification of organic molecules from biomass comprises extracting one or more products from the biomass using an extraction solvent to solvate the products, contacting the biomass with a reactant during the extracting, recovering the one or more products, performing ultrafiltration to remove impurities from the one or more products to produce a filtered extract, extracting oils in the filtered extract using adsorption to produce a de-oiled extract, performing transesterification or hydrolysis on the de-oiled extract, and performing adsorptive purification on the ferulic acid, coumaric acid, ferulate, coumarate, or a combination thereof. The one or more products comprise extracted organic molecules comprising a ferulate or a coumarate, and the one or more products are separated from the biomass as a liquid extract.

摘要： 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.
