从楼主的两种图来看,是一种东西(异构体混合物)的不同商品名,因为是混合异构体,异构体含量稍有差异。

Hercolyn® D
Hercolyn® D methyl ester of hydrogenated rosin is a light amber liquid resinous tackifier and plasticizer. Being hydrogenated, it has marked resistance to aging. It is given a special steam purification treatment to assure consistent mild odor. Hercolyn D resin is used extensively in fragrance compounds, where it functions as a fixative, carrier, and compatibilizer, and in the formulation of chewing gum base. It is also used as a resinous plasticizer or tackifier in finished products such as lacquers, inks, adhesives, floor tiles, artificial leather, and antifouling paints.
