摘要： Presently described are purification methods for modified rosin compositions, purified compositions, and articles thereof. The methods described herein use a solvent. The solvent can include at least one of a hydrocarbon solvent, a bio-based solvent, or a combination thereof. The purified modified rosin compositions have higher amounts of the modified rosin as compared with modified rosin compositions that have not been purified.

摘要： A process for deodorizing a rosin ester composition is disclosed. The process employs an adsorptive bed containing an adsorbent material. The adsorbent material comprises silica adsorbent having an average pore size between 50-200 Å, 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 deodorized rosin ester composition has an odor intensity reduction of at least 1 unit on odor intensity scale of Offensive Odor Control Act as compared to the rosin ester feedstock. In embodiment, the deodorizing treatment comprises using multi-staged adsorbent system with an adsorbent column having multiple layers of different adsorbent materials.

摘要： 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 Å, 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.

摘要： A method, system, apparatus, and/or device for removing resin from material. The method, system, apparatus, and/or device may include a washer configured to receive water from a water source and air from an air source into an interior cavity of the washer via an inlet, the washer including a first filter located within the interior cavity, where the interior cavity is configured to store a material, the interior cavity is configured to direct a flow of the water and the air in a defined pattern to remove a resin from the material, and the washer comprises an opening covered by the first filter. The first filter may be configured to allow the water, the air, and the resin to exit the opening while restricting the material from exiting the opening.

摘要： Precipitated bacterial capsular polysaccharides can be efficiently re-solubilized using alcohols as solvents. The invention provides a process for purifying a bacterial capsular polysaccharide, comprising the steps of (a) precipitation of said polysaccharide, followed by (b) solubilization of the precipitated polysaccharide using ethanol. CTAB can be used for step (a). The material obtained, preferably following hydrolysis and sizing, can be conjugated to a carrier protein and formulated as a vaccine. Also, in vaccines comprising saccharides from both serogroups A and C, the invention provides that the ratio (w/w) of MenA saccharide:MenC saccharide is >1.
