摘要： A collector composition comprising (a) refined tall oil wherein the refined tall oil is any tall oil that has been subjected to one or more refining or processing steps that results in an increase in acid value; and (b) a fatty acid wherein the refined tall oil has an acid value of at least 90 mg KOH/g and a weight average molecular weight of at least 750 g/mol. A mineral slurry comprising (a) an ore comprising a mineral of interest; (b) a collector composition comprising (i) a refined tall oil; and (ii) a fatty acid; and (c) a liquid. A method for the beneficiation of an ore, the method comprising (a) preparing a slurry comprising the ore dispersed in a liquid; (b) contacting the slurry with a collector composition comprising a refined tall oil; and (c) recovering a beneficiated ore.

摘要： 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.
摘要翻译：本文提供了制备松香酯的方法。所述方法可以包括使松香酯与微孔吸附剂接触。用微孔吸附剂如活性炭处理可以改善松香酯的颜色（例如，将松香酯的纯加德纳颜色降低至少1加德纳颜色单位），降低松香酯中硫的浓度（例如，将松香酯中的硫的浓度降低至少50ppm）或其组合。还描述了通过本文所述方法制备的松香酯酯，以及其使用方法。

摘要： 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.
摘要翻译：提供松香酯。松香酯可以表现出改善的颜色（例如，松香酯可以具有8.5或更低的纯Gardner颜色），改善的氧化稳定性（例如当与松香酯组合存在1000ppm或更少的抗氧化剂时，松香酯可以在130℃下显示出至少75分钟的氧化诱导时间），改善的颜色稳定性（例如，当加热到160℃的温度时，松香酯可以显示出小于加纳德颜色的10％变化，三个小时），或其组合。还提供了包含松香酯的聚合物组合物，以及制备松香酯的方法。
