Abstract: A process for reducing or removing at least 90% of sulfur in a tall oil composition, e.g., to a level of 15 ppm or less is disclosed. The process employs at least a first desulfurization and a second desulfurization treatment in parallel or in series. The first treatment comprises adsorptive desulfurization, wherein the adsorbent material comprises silica adsorbent having an average pore size between 50-200 ?, BET surface area of at least 300 m2/g, pore volume of 1.20 to 3.00 cc/g, and a silanol [Si—OH] level of 0.5 to 5 unit/nm2. The second desulfurization treatment is selected from adsorptive treatment, heat treatment, distillation, extraction, oxidation, reduction, hydrogenation, and sulfur scavenging for a reduced sulfur content.

Abstract: Methods of selectively modifying lignin, polycarboxylated products thereof, and methods of deriving aromatic compounds therefrom. The methods comprise electrochemically oxidizing lignin using stable nitroxyl radicals to selectively oxidize primary hydroxyls on ?-O-4 phenylpropanoid units to corresponding carboxylic acids while leaving the secondary hydroxyls unchanged. The oxidation results in polycarboxylated lignin in the form of a polymeric ?-hydroxy acid. The polymeric ?-hydroxy acid has a high loading of carboxylic acid and can be isolated in acid form, deprotonated, and/or converted to a salt. The ?-hydroxy acid, anion, or salt can also be subjected to acidolysis to generate various aromatic monomers or oligomers. The initial oxidation of lignin to the polycarboxylated form renders the lignin more susceptible to acidolysis and thereby enhances the yield of aromatic monomers and oligomers obtained through acidolysis.
Abstract: The invention relates to a formulation comprising: —a first component which is formed from at least one isocyanate and at least one amino resin, wherein said amino resin is the condensation product of an aldehyde with a compound selected from the group comprising urea, melamine, benzoguanamine, glycoluril, acetoguanamine and mixtures thereof; and —a second component comprising at least one polyether, wherein said polyether comprises at least one ethylene oxide moiety and at least one isocyanate reactive group selected from the group comprising hydroxyl, amino, epoxy, and thiol, preferably hydroxyl.

Abstract: Boronic acid monomers, methods of making boronic acid monomer, and the like, are provided. Embodiments of the present disclosure are advantageous in that the boronic acid monomers are water soluble at a neutral pH, which is uncommon for boronic acids. As a result, the boronic acid monomers can be used in aqueous polymerization reactions with other hydrophilic monomers to yield polymers including boronic acids and esters.
