    Abstract: In one respect, this invention is a lubricating composition which comprises a polyaryl ether lubricating fluid and an additive which is (a) cesium carbonate, (b) cesium phosphate, or (c) a benzoate of cesium, rubidium, or lithium wherein the additive is present in the lubricating composition in an amount effective to produce an antioxidative effect in the lubricating composition. In another respect, this invention is a process for reducing the rate of oxidation in a polyaryl ether lubricating fluid which comprises adding an additive wherein the additive is (a) cesium carbonate, (b) cesium phosphate, or (c) a benzoate of cesium, rubidium, or lithium to the polyaryl ether lubricating fluid in an amount effective to produce an antioxidative effect in the lubricating composition.

    Abstract translation: 在一个方面,本发明是一种润滑组合物,其包含聚芳基醚润滑流体和添加剂,其为(a)碳酸铯,(b)铯磷酸盐或(c)铯,铷或锂的苯甲酸盐,其中添加剂 以有效地在润滑组合物中产生抗氧化作用的量存在于润滑组合物中。 在另一方面,本发明是降低聚芳基醚润滑流体中的氧化速率的方法,其包括添加添加剂,其中添加剂是(a)碳酸铯,(b)磷酸铯或(c)铯的苯甲酸酯 ,铷或锂,以有效地在润滑组合物中产生抗氧化作用。
