  The present invention relates to thioesters having the structural formula: wherein Rx is selected from the group of formulae consisting of: R¹, R² and R³ are independently selected from the group of radicals consisting of hydrogen or methyl; R⁴ and R⁵ are independently selected from the group of radicals consisting of hydrogen, alkyls having 1 to 18 carbon atoms, aryls having 6 to 10 carbon atoms, aralkyls having 7 to 9 carbon atoms, and radicals of the formula: and R⁶ is selected from the group of radicals consisting of alkyls having 1 to 24 carbon atoms, aryls having 6 to 12 carbon atoms and aralkyls having 7 to 12 carbon atoms. These thioesters are particularly useful as a synergist for conventional phenolic and amine antioxidants.

  本发明涉及结构式如下的硫酯： 其中 Rx 选自下列式组 R¹、R² 和 R³ 分别独立地选自氢或甲基组成的基团组；R⁴ 和 R⁵ 分别独立地选自氢、具有 1 至 18 个碳原子的烷基、具有 6 至 10 个碳原子的芳基、具有 7 至 9 个碳原子的烷基和式中的基团组成的基团组： 和 R⁶ 选自由具有 1 至 24 个碳原子的烷基、具有 6 至 12 个碳原子的芳基和具有 7 至 12 个碳原子的烷基组成的基团组。 这些硫代酯类特别适用于作为传统酚类和胺类抗氧化剂的增效剂。

  Embodiments of the present disclosure provide for novel strategies to harvest algal lipids using mollusks which after feeding algae from the growth medium can convert algal lipids into their biomass or excrete lipids in their pseudofeces which makes algae harvesting energy efficient and cost effective. The bioconverter, filter-feeding mollusks and their pseudofeces can be harvested and converted to biocrude using an advanced thermochemical liquefaction technology. Methods, systems, and materials are disclosed for the harvest and isolation of algal lipids from the mollusks, molluscan feces and molluscan pseudofeces.
