    Abstract: A process and apparatus for recovering crude tall oil are disclosed. Acidulation of a crude tall oil soap stream generates a spent acid stream that comprises lignin and entrained crude tall oil. By subjecting the spent acid stream to dissolved gas flotation, a lignin phase comprising entrained crude tall oil can be recovered and causticized, resulting in recovery of most of the crude tall oil that was present in the spent acid stream. A clarified spent acid stream is also generated, which can be treated with caustic and utilized for a soap washing process that integrates easily into the overall CTO recovery process. The apparatus comprises a crude tall oil acidulation unit, a dissolved gas flotation unit, a causticizing unit, and a soap separation unit. The inventive process marries dissolved gas flotation, a well-known water treatment process, with causticization of a recovered lignin phase, a step known from batch acidulation, to improve overall tall oil recovery from a continuous process.

    Abstract: Rosin esters are provided. The rosin esters can exhibit improved color (e.g., the rosin ester can have a neat Gardner color of 8.5 or less), improved oxidative stability (e.g., when 1000 ppm or less of an antioxidant is present in combination with the rosin ester, the rosin ester can exhibit an oxidative-induction time at 130° C. of at least 75 minutes), improved color stability (e.g., the rosin ester can exhibit less than a 10% change in neat Gardner color when heated to a temperature of 160° C. for a period of three hours), or combinations thereof. Also provided polymeric compositions comprising the rosin esters, as well as methods of making the rosin esters.

    Abstract: Provided herein are methods of making rosin esters. The methods can involve contacting a rosin ester with a microporous adsorbent. Treatment with a microporous adsorbent, such as an activated carbon, can improve the color of the rosin ester (e.g., reduce the neat Gardner color of the rosin ester by at least 1 Gardner color unit), reduce the concentration of sulfur in the rosin ester (e.g., reduce the concentration of sulfur in the rosin ester by at least 50 ppm), or combinations thereof. Rosin esters prepared by the methods described herein, as well as methods of using thereof, are also described.

    Abstract: Disclosed are compositions which include an ethylene polymer derived from at least one polar monomer with one or more ester groups, which polymerize with ethylene, (e.g., a copolymer, or low molecular weight copolymer having a relatively high melt index, derived from ethylene and vinyl acetate and/or a copolymer, or low molecular weight copolymer having a relatively high melt index, derived from ethylene and «-buty! acrylate) and a rosin ester. The rosin ester can have a low hydroxy! number (e.g., a hydroxy! number six or five or less), a low acid number (e.g., an acid number of ten or less), a relatively low PAN number (e.g., a PAN number less than twenty-two or in between eight and twenty), a relatively high third moment or third power average molecular weight (Mz), (e.g., an Mz value in between 2500 and 12000 g/mol), a low sulfur content (e.g., a sulfur content lower than 600 ppm prior to antioxidant addition) or combinations thereof. The compositions can exhibit a high heat stress resistance (e.g., a heat stress pass temperature value higher than 52° C. or in between 48° C. and 60° C.) and/or improved viscosity stability and/or color stability upon thermal aging and/or improved compatibility.
