    • Methods for making a fatty acid dimer composition. A first catalyst and a mixture that includes fatty acids and rosin acids can be combined to produce a first mixture. The mixture that includes the fatty acids and rosin acids can have a first dehydroabietic acid concentration. The first mixture can be heated to a first temperature that is less than 250C to produce a first reaction mixture having a second dehydroabietic acid concentration greater than the first dehydroabietic acid concentration. The first reaction mixture can be heated to a second temperature that is at 250C or greater to produce a second reaction mixture. The second reaction mixture can include rosin oil, oligomeric acids, and monomer acids, and can have a rosin oil yield of greater than 25%.
    • 制备脂肪酸二聚体组合物的方法。 可以将第一催化剂和包含脂肪酸和松香酸的混合物混合以产生第一混合物。 包含脂肪酸和松香酸的混合物可具有第一脱氢松香酸浓度。 可以将第一混合物加热至小于25℃的第一温度以产生具有大于第一脱氢松香酸浓度的第二脱氢松香酸浓度的第一反应混合物。 可以将第一反应混合物加热至25℃或更高的第二温度以产生第二反应混合物。 第二反应混合物可以包括松香油,低聚酸和单体酸,并且可以具有大于25%的松香油产率。
